I. Overview [ 1 ] These reasons address two decisions of the Federal Court striking the appellants’ statements of claim. I will refer to the appeals as either the La Rose appeal or the Misdzi Yikh appeal, as necessary. [ 2 ] The appellants in the La Rose appeal are 15 children and youth (the youth appellants) who were between the ages of 10 and 19 at the time that they filed their statement of claim. They reside across Canada in seven provinces and one territory. Together, the youth appellants initiated an action against Canada for its failure to address the problem of climate change.

They sought remedies under sections 7 and 15 of the Canadian Charter of Rights and Freedoms ,

Part I of the Constitution Act, 1982 , being

Schedule B to the Canada Act 1982 (U.K.), 1982, c. 11 (the Charter ), contending that the impacts of climate change " “interfere with their physical and psychological integrity and their ability to make fundamental life choices” " (youth appellants’ statement of claim at para. 6).

They assert that Canada’s legislative response to climate change has a disproportionate effect on their generation and that they have suffered—and will continue to suffer—the consequences, given their vulnerability and age. [ 3 ] The appellants in the Misdzi Yikh appeal are two Wet’suwet’en House groups that comprise the Likhts’amisyu (Fireweed) Clan, Misdzi Yikh (Owl House) and Sa Yikh (Sun House) and each of the House groups’ dini ze’ or Head Chief (the Dini Ze’).

The Dini Ze’ of each Wet’suwet’en House group embodies their House and is responsible for the protection of the House’s members, possessions, and territories. [ 4 ] The Dini Ze’ launched their claim as a representative proceeding under Rule 114 of the Federal Courts Rules, S.O.R./98-106 , contending that Canada has contributed to climate change in a way that poses a " “threat to their identity, to their culture, to their relationship with the land and the life on it, and to their food security” " (Dini Ze’s statement of claim at para. 2).

They say the legislative response to climate change and executive actions exacerbate the threat and violate their protections and rights under sections 7 and 15 of the Charter . They say that the legislation and regulations authorizing the current levels of greenhouse gas (GHG) emissions, along with the continued and past approvals of GHG-emitting projects, result in Canada breaching its obligations under international law in the Paris Agreement , 12 December 2015, U.N.T.S. 3156 (p. 79) ( Paris Agreement ). This constitutes a breach of domestic law, as the targets in the Paris Agreement have been enshrined in

section 7 of the Canadian Net-Zero Emissions Accountability Act , S.C. 2021, c. 22 . In addition, they argue that Parliament has exceeded the general power under

section 91 of the Constitution Act, 1867 (U.K.), 30 & 31 Vict., c. 3 , reprinted in R.S.C. 1985, Appendix II, No. 5 (the Constitution Act, 1867 ) to make laws for the peace, order and good government of the country (the general power). [ 5 ] Canada responded to each of these actions with a motion to strike. Canada’s position is that GHG-induced climate change is real, scientifically established and objectively measurable.

GHG emissions are having demonstrable negative impacts on the Canadian environment, the economy and the health of Canadians, now, and will have grave consequences in the future unless urgently addressed.

However, Canada contended that the appellants’ claims were not justiciable, or, if they were justiciable, disclosed no cause of action on the basis that there is no nexus between the harm suffered and to be suffered and the impugned legislation. [ 6 ] The Federal Court granted Canada’s motions, striking the youth appellants’ statement of claim ( 2020 FC 1008 , per Manson J.) and the Dini Ze’s statement of claim ( 2020 FC 1059 , per McVeigh J.), both without leave to amend.

II. Decisions below [ 7 ] I will first describe Manson J.’s decision, which relates to the La Rose appeal, and then turn to McVeigh J.’s decision in the Misdzi Yikh matter. [ 8 ] Manson J. struck the youth appellants’ statement of claim and, as noted, did so without leave to amend ( La Rose Reasons at para. 101 ). He found that their claims under sections 7 and 15 of the Charter were not justiciable, as they were so political that they were not suitable for judicial determination.

Manson J. held that the youth appellants’ " “approach of alleging an overly broad and unquantifiable number of actions and inactions on the part of [Canada] does not meet [the] threshold requirement [that a policy response be translated into law or state action prior to constitutional review] and effectively attempts to subject a holistic policy response to climate change to Charter review” " ( La Rose Reasons at para. 40 ).

He added that even if these claims were justiciable, they failed to disclose a sufficiently discrete instance of state action so as to permit any Charter analysis ( La Rose Reasons at paras. 59, 61, 79 ). Manson J. also noted that the remedies sought by the youth appellants could not practically address any Charter violation, if proved ( La Rose Reasons at para. 55 ). [ 9 ] Importantly for the purposes of these appeals, Manson J. did not strike the youth appellants’ claim under

section 7 of the Charter on the basis that it asserted positive rights, noting the judiciary’s reluctance to definitively cap the rights protected by

section 7 in Gosselin v. Québec (Attorney General) , 2002 SCC 84 , [2002] 4 S.C.R. 429 [ Gosselin ] and Kreishan v. Canada (Citizenship and Immigration) , 2019 FCA 223 , [2020] 2 F.C.R. 299 [ Kreishan ] ( La Rose Reasons at paras. 67-70 ). [ 10 ] In dealing with the youth appellants’ argument that Canada has a duty to preserve and protect public resources, Manson J. determined that this public trust claim was justiciable but disclosed no reasonable cause of action ( La Rose Reasons at paras. 58 and 87 ). He considered British Columbia v.

Canadian Forest Products Ltd. , 2004 SCC 38 , [2004] 2 S.C.R. 74 [ Canfor ] and Burns Bog Conservation Society v. Canada , 2014 FCA 170 , 464 N.R. 187 [ Burns Bog ] , which the youth appellants argued showed the possibility that a public trust doctrine may exist at common law, but ultimately found that these authorities did not provide a legal foundation for the " “breadth of the rights and actionable interests” " raised in the youth appellants’ claim ( La Rose Reasons at paras. 88-92 ).

Manson J. characterized the claim under the public trust doctrine as " “reflective of an ‘outcome’ in search of a ‘cause of action’” " ( La Rose Reasons at para. 88 ). [ 11 ] In the Dini Ze’s action, McVeigh J. granted Canada’s motion and struck the Dini Ze’s statement of claim for non-justiciability, without leave to amend ( Misdzi Yikh Reasons at paras. 8 and 116 ). McVeigh J. concluded that the Dini Ze’s proposed amendments to their statement of claim would not cure its defects ( Misdzi Yikh Reasons at para. 114 ). [ 12 ] McVeigh J. highlighted that the Dini Ze’ were in essence arguing for an

interpretation of the general power that would require Parliament to enact specific laws, and that this

interpretation would impose a positive duty on Parliament previously unknown in Canadian law ( Misdzi Yikh Reasons at para. 46 ). She disagreed that the general power could create such a duty and struck this claim ( Misdzi Yikh Reasons at paras. 27, 84-85 ). [ 13 ] Turning to the Dini Ze’s Charter claims, McVeigh J. noted that the Dini Ze’ had pled no specific laws or state actions that breached their

section 7 or 15 Charter rights ( Misdzi Yikh Reasons at paras. 50, 75, 91 ). She further held that, in any event, the Charter claims fell beyond the courts’ institutional capacity due to the claims’ broad political nature ( Misdzi Yikh Reasons at paras. 56-57, 72, 74, 77 ). She specifically noted that " “[t]he issue of climate change, while undoubtedly important, is inherently political, not legal, and is of the realm of the executive and legislative branches of government” " ( Misdzi Yikh Reasons at para. 77 ). [ 14 ] McVeigh J. declined to permit the Charter claims to proceed to trial on the possibility that

section 7 or 15 may come to encompass positive obligations ( Misdzi Yikh Reasons at para. 58 ): Gosselin left the door slightly open regarding positive obligations that may be imposed on a government to remedy violations of the Charter being justiciable. However, this is not such a case. There is no impugned law or action to evaluate, there are no specific allegations of government actions, and the positive obligations (or limitations) sought by the Dini Ze’ are vague and without the focus to affect the desired results. III.

Issues on appeal [ 15 ] The youth appellants argue that Manson J. erred by concluding that their Charter claims were not justiciable based on the " “broad and diffuse” " nature of the asserted state conduct. They argue that, despite the breadth of their claims, the Federal Court would nevertheless be able to apply a " “judicially discoverable standard to a discrete and manageable aspect of the government’s conduct” " (youth appellants’ memorandum of fact and law at para. 4).

They further argue that Manson J. erroneously concluded that their public trust claim was doomed to fail, as the Supreme Court has left open the possibility that such a claim may succeed, and that the cause of action marks only an incremental change to the common law as it presently exists.

Finally, the youth appellants say that Manson J. prematurely assessed the viability of the remedies they sought, an assessment they say ought to have been left to a trial judge. [ 16 ] The Dini Ze’ appellants take a position similar to the youth appellants with respect to McVeigh J.’s decision to strike their Charter claims, arguing that the claims were in fact justiciable. They also submit that McVeigh J. misconstrued their claim under the general power in

section 91 of the Constitution Act, 1867 as asserting a positive duty to legislate.

Similarly, the Dini Ze’ appellants say that McVeigh J. overlooked what they describe as relevant decisions in the United Kingdom (the UK) that support their argument that the general power may be interpreted as a limitation on the government’s ability to legislate. [ 17 ] In response, Canada contends that the appellants’ challenges to Canada’s laws are so broad and diffuse that they disregard Canada’s separation of powers—effectively asking the judiciary to undertake the function reserved to the legislature or the executive—and are accordingly unsuitable for judicial adjudication.

Canada further contends that the appellants’

section 7 and

section 15 claims are positive rights claims, which would obligate Parliament to act affirmatively. Canada argues that positive obligations do not figure in any Charter

jurisprudence to date and that the claims fail on that basis alone. Canada stresses that the appellants fail to specifically identify theparticular laws or policies that breach their Charter rights, and that the claims fail for lack of particularity. Finally, Canada says thatneither the youth appellants’ public trust claim nor the Dini Ze’s

section 91 claim disclose a reasonable cause of action, given theabsence of any jurisprudence in support of the asserted public trust or the proposed

interpretation of the general power. IV. Motions to strike [18] The relevant inquiry on motions to strike is whether it is plain and obvious that the pleaded claims have no reasonable prospect ofsuccess (Atlantic Lottery Corp. Inc. v. Babstock, 2020 SCC 19, [2020] 2 S.C.R. 420 at para. 14 [Atlantic Lottery]; Canada (AttorneyGeneral) v. Nasogaluak, 2023 FCA 61, 2023 CarswellNat 697 (WL Can) at para. 18, leave to appeal to SCC requested). [19] Three ancillary principles inform the application of this test. First, the facts are to be taken as proven unless they are manifestlyincapable of proof.

Second, the pleading must be read generously, and, recognizing that the law is not static and evolves to address newand emerging situations, a motions judge must err on the side of permitting novel but arguable claims to proceed to trial (R. v. ImperialTobacco Canada Ltd., 2011 SCC 42, [2011] 3 S.C.R. 45 at para. 21 [Imperial Tobacco]; Mohr v. National Hockey League, 2022 FCA145, 472 D.L.R. (4th) 413 at para. 48, leave to appeal to SCC refused, 40426 (20 April 2023)). Third, the onus is on the defendant whoseeks to establish that there is no reasonable cause of action (Edell v.

Canada, 2010 FCA 26, 399 N.R. 115 at para. 5). [20] The question in these appeals lies in whether the claims fail on the basis of justiciability, the substantive law, the pleadings, orperhaps on all three grounds. If the issues raised in the claims are not justiciable, that is a complete answer to the matter—the claimsmust be struck. But if the claims are justiciable, the claims may also fail on either the second objection—namely, that they disclose noreasonable cause of action—or on the third, a failure of the pleadings.

The second objection, if successful, would normally be fatal; thethird one, in appropriate circumstances, may be remedied by amendments. [21] I will explain why the claims based on the general power, the public trust doctrine and

section 15 of the Charter fail. They have noreasonable prospect of success and were properly struck without leave to amend. [22] The

section 7 claims are justiciable, but nevertheless should be struck, albeit with leave to amend. The

section 7 claims fail, notbecause they are destined to fail in this context or have no reasonable prospect of success, but because the pleadings of the

section 7claims as framed are incompatible with constitutional adjudication. The

section 7 claims fail not because they are destined to fail in thiscontext or have no reasonable prospect of success, but because the expansive and diffuse scope of the pleadings as framed areincompatible with constitutional adjudication. V. Justiciability [23] I begin with justiciability. As noted, Manson and McVeigh JJ. took somewhat different approaches to the issue. [24] Justiciability distinguishes claims suitable for judicial determination from those that are not.

When assessing justiciability, "“[t]hecourt should ask whether it has the institutional capacity and legitimacy to adjudicate the matter”" (Highwood Congregation ofJehovah’s Witnesses (Judicial Committee) v. Wall, 2018 SCC 26, [2018] 1 S.C.R. 750 [Highwood] at para. 34, citing Lorne M. Sossin,Boundaries of Judicial Review: The Law of Justiciability in Canada, 2nd ed. (Toronto: Carswell, 2012) at 7 and 294) [Sossin,Boundaries of Judicial Review]). The question of institutional capacity asks what the court can do; the legitimacy question asks what thecourt should do.

Courts decline to adjudicate issues that ask that they act beyond their institutional capacity or legitimacy. [25] Two considerations motivate the justiciability analysis. The first is constitutional, the second, more pragmatic. [26] The constitutional consideration is the court’s respect for its role in a Westminster parliamentary democracy. The wisdom ofpolitical and policy choices made by Parliament in response to social, economic and environmental problems is separate and apart fromtheir constitutionality.

Courts do not second-guess the wisdom of Parliament’s choice; rather, they assess the validity of the resulting lawand its application and must be mindful of the boundaries between the two. The justiciability inquiry involves a weighing of theappropriateness, as a matter of constitutional judicial policy, of the courts deciding a given issue or instead deferring to the otherbranches of government (Canada (Auditor General) v.

Canada (Minister of Energy, Mines and Resources), (SCC),[1989] 2 S.C.R. 49, 61 D.L.R. (4th) 604 at 90-91). [27] The pragmatic consideration arises from the limitations on a court’s ability to fashion and implement remedies. This is a componentof the institutional limitation. [28] No firm criteria for assessing justiciability exist, and the boundaries between justiciable and non-justiciable matters are not alwaysclear. The issue often distills to a single question as to whether the claim has a sufficient legal component upon which a court canadjudicate.

Here too, the answer to that question may be obscured by the moral, social or political dimensions of the case that make itinappropriate for a court to decide (Tanudjaja v. Canada (Attorney General), 2014 ONCA 852, 379 D.L.R. (4th) 467 at para. 33[Tanudjaja]; but compare: Operation Dismantle v. The Queen, (SCC), [1985] 1 S.C.R. 441, 18 D.L.R. (4th) 481 at 472[Operation Dismantle]; Reference Re Canada Assistance Plan (B.C.), (SCC), [1991] 2 S.C.R. 525, 83 D.L.R. (4th) 297at 545-546). [29] But we do know that claims are not rendered non-justiciable simply because they raise complex or controversial issues.

Courts mustbe flexible in their approach to determining whether a matter is justiciable and consider the context of the claim in question (Highwoodat para. 34). On this point, the language of the Supreme Court is unequivocal: "“The fact that the matter is complex, contentious or ladenwith social values does not mean that the courts can abdicate the responsibility vested in them by our Constitution to review legislationfor Charter compliance when citizens challenge it”" (Chaoulli v. Quebec (Attorney General), 2005 SCC 35, [2005] 1 S.C.R. 791 at para.107 [Chaoulli]).

[30] Courts have not shied away from addressing controversial issues that raise many layered and complex policy questions. Examplesreadily spring to mind: challenges to legislation reducing access to private medical treatment (Chaoulli); whether the waiting times forsurgery infringe

section 7 (Cambie Surgeries Corporation v. British Columbia (Attorney General), 2022 BCCA 245, 473 D.L.R. (4th)1); whether the provisions of the Criminal Code, R.S.C. 1985, c. C-46 with regard to prostitution infringe

section 7 (Canada (AttorneyGeneral) v. Bedford, 2013 SCC 72, [2013] 3 S.C.R. 1101 [Bedford]); access to abortion (R. v. Morgentaler, (SCC),[1988] 1 S.C.R. 30, 44 D.L.R. (4th) 385); the availability of supervised injection sites to improve the safety of drug use (Canada(Attorney General) v. PHS Community Services Society, 2011 SCC 44, [2011] 3 S.C.R. 134 [PHS]); and the effects of prohibitions onphysician-assisted dying (Carter v.

Canada (Attorney General), 2015 SCC 5, [2015] 1 S.C.R. 331 [Carter]). [31] Here, the motions judges found that the claims were not justiciable because they would require the Court to adjudicate on broad anddiffuse aspects of government conduct, involving matters of economics and foreign and trade policy, under programs administered byvarious departments.

The question of climate change was “controversial” and “political” and therefore not one for the courts. [32] I do not agree, respectfully, that the claims are not justiciable simply because the question of climate change is complex or becausethe legislation reflects a political choice on how to address the problem. While the legislation may be controversial, this does not effacethe fact that the debate has been crystallized into law; legislative choices have been made. For example, the

preamble of the GreenhouseGas Pollution Pricing Act, S.C. 2018, c. 12, s. 186 recognizes that the Government of Canada must, and will, take steps to alleviate thepressures of climate change, stating that "“the Government of Canada is committed to achieving Canada’s Nationally DeterminedContribution—and increasing it over time—under the Paris Agreement by taking comprehensive action to reduce emissions across allsectors of the economy, accelerate clean economic growth and build resilience to the impacts of climate change”". [33] Political choice underlies all legislation and some exercises of executive discretion; both are invariably informed by a wide range ofpublic policy considerations.

But once the choices are made, the policy trade-offs considered and the legislative response crystallized,the law is not immunized from Charter scrutiny. As the Supreme Court held in PHS, "“when a policy is translated into law or stateaction, those laws and actions are subject to scrutiny under the Charter”" (PHS at para. 105).

It must not be forgotten that the target ofthe appellants’ claims is legislation—existing laws, regulatory instruments and Orders in Council. [34] Matters of public policy are within the exclusive domain of the executive and legislative branches, and are, on their own,demonstrably unsuitable for adjudication. Because of this, where a case engages only the underlying policy, a court will strike a pleadingas not justiciable (Sossin, Boundaries of Judicial Review at 267-270).

On the other hand, in concurring reasons on a point accepted bythe majority, Wilson J. stated that a court cannot relinquish its jurisdiction over an issue merely because it raises a "“political question”"(Operation Dismantle at 459 and 472).

She went on to distinguish, in the justiciability context, pure policy questions from legal questionswith some policy aspect to them (Operation Dismantle at 472): I would conclude, therefore, that if we are to look at the Constitution for the answer to the question whether it is appropriatefor the courts to “second guess” the executive on matters of defence, we would conclude that it is not appropriate.

However,if what we are being asked to do is to decide whether any particular act of the executive violates the rights of the citizens,then it is not only appropriate that we answer the question; it is our obligation under the Charter to do so. [35] Public controversy or the political context associated with legislation cannot therefore be a standalone ground to deem the claimnon-justiciable (Operation Dismantle at 472), and the "“political question”" doctrine found in the United States has never been acceptedin Canada (D.

Geoffrey Cowper & Lorne Sossin, “Does Canada Need a Political Questions Doctrine?” (2002) 16 S.C.L.R. (2d) 343 at345). The Supreme Court has expressly rejected the doctrine, and, as just noted, when the claim is properly framed as a breach of Charterright (an important caveat and to which I will return), the court has an obligation to decide the matter (Operation Dismantle at 472).

Onehears in the reasons of the Federal Court a faint echo of the political question doctrine. [36] As previously described, policy considerations are inherent to all government action, but that fact alone does not insulate the lawfrom judicial scrutiny. What matters in an assessment of justiciability, instead, is the presence of a sufficient legal component or legalanchor to the claim. Justiciability, in the end, asks whether the court can adjudicate the issues against an objective legal standard.

In thissense, justiciability analysis requires some understanding of the jurisprudence that underlies the claim, which in turn requires asomewhat probing examination of the substantive allegations of the claim. [37] Tanudjaja is a good example of the requirement that a claim have a sufficient legal component in order to be justiciable. There, theappellants sought declarations that Ontario’s failure to effectively address the problem of homelessness violated their rights undersections 7 and 15 of the Charter.

The appellants challenged no law or application of law in particular—they simply challenged thegovernments’ overall approach to the social problem. The claims lacked a legal component required for judicial adjudication andtherefore were not justiciable (Tanudjaja at paras. 19, 27, 35-56). [38] Here, in contrast, the appellants link the

section 7 deprivation to the failure of Canada to meet its commitments in the ParisAgreement (Nationally Determined Contributions), commitments ratified by Parliament, and hence legally defined, objective standardsagainst which the Charter claims can be assessed. The claims do not seek to tell Canada how to fulfill its commitments. In this regard, theFederal Court mischaracterized the claims when it held the claims were challenges to policy. [39] Canada relies on Friends of the Earth v.

Canada (Governor in Council), 2008 FC 1183, [2009] 3 F.C.R. 201 [Friends of the Earth]as authority for the proposition that the doctrine of justiciability precludes judicial intervention on climate change matters. [40] In that case, the applicant sought declaratory and mandatory relief in connection with the alleged failures of the Minister of theEnvironment and the Governor in Council to comply with their duties under the Kyoto Protocol Implementation Act, S.C. 2007, c. 30(the KPIA).

The applicant argued that the Minister was required under the KPIA to prepare a climate change plan that satisfied Canada’sobligations under the Kyoto Protocol, and that the Governor in Council was required to take regulatory action to ensure that Canadawould meet its Kyoto Protocol commitments (Friends of the Earth at paras. 3-5). [41] The judicial review application was dismissed on the basis that it did not raise justiciable issues (Friends of the Earth at paras. 46and 48). The Federal Court found that the KPIA did not impose duties on either the Minister or the Governor in Council that required

strict compliance with the Kyoto Protocol, nor did the relevant portions of the KPIA contemplate an enforcement role for the court(Friends of the Earth at paras. 33-35, 38-45). Mandamus was refused because the Minister’s obligation under the Act was to file a reportto Parliament; no public duty was owed, and it was on this basis that the application was dismissed (see, as a recent application of thesame principle, Sierra Club of British Columbia Foundation v.

British Columbia (Minister of Environment and Climate ChangeStrategy), 2023 BCSC 74, 54 C.E.L.R. (4th) 328). [42] The Federal Court’s conclusion on justiciability was guided entirely by the content of the KPIA; as the Federal Court noted, "“[t]hejusticiability of all of these issues is a matter of statutory

interpretation directed at identifying Parliamentary intent”" (Friends of theEarth at para. 31). Friends of the Earth does not, therefore, stand for the proposition that all claims addressing climate change areinherently non-justiciable; rather, the application was struck on the basis that the Minister’s duties under the KPIA were owed toParliament and that the legislation did not create a public duty enforceable by mandamus.

Neither of these circumstances arise in thepresent appeals. [43] To the extent that the Federal Court in Friends of the Earth addressed the substance of the government’s report and its own ability toadjudicate on the government’s degree of compliance with the Kyoto Protocol, the observations were both obiter and hypothetical, noreport ever having been prepared. [44] I also note the decision of the Ontario Superior Court of Justice in Mathur v. Ontario, 2020 ONSC 6918, 42 C.E.L.R. (4th) 124[Mathur 2020].

There, like here, the underlying issue was a Charter challenge to the adequacy of a government’s response to climatechange. The Ontario Superior Court dismissed Ontario’s motion to strike the applicants’ application on the basis of non-justiciability,holding instead that the application had a reasonable prospect of success and that the claim properly challenged specific laws and specificgovernment conduct (Mathur 2020 at paras. 132, 139-140).

Neither the complexity nor the controversial nature of the subject matter ofthe claim rendered it inherently non-justiciable. [45] Here, the appellants have pled, in the legislation and Orders in Council, an objective legal basis or standard against which

section 7rights can be assessed. There is, therefore, a sufficient legal component to their claims, and the claims satisfy the legitimacy portion of ajusticiability analysis.

However, this is not a complete answer to the question of whether the appellants’ claims, as pleaded, arejusticiable; there remain the questions of institutional competence and remedies. [46] Both motions judges ruled that the claims failed because they were overly broad and diffuse: they were based on multiple pieces oflegislation, prior project approvals by way of Orders in Council, international agreements, domestic policy relating to climate change,and Canada’s participation in industries and activities involving fossil fuels through subsidies, grants and tax measures.

In La Rose, theFederal Court also reviewed some of the remedies sought and concluded that they overreached the institutional competence of the Court(La Rose Reasons at paras. 8-10, 40 and 46). [47] In some cases, remedies sought may be so clearly offside that they taint the proceeding as a whole. Remedies must be capable ofenforcement. If a court cannot tailor effective, enforceable remedies to meaningfully address the asserted harms, the claim may not bejusticiable. [48] But remedies, at least at the outset of litigation, are not necessarily determinative of justiciability.

For example, declaratory relief is,on occasion, granted but suspended when enforcement is inconsistent with the role of the judiciary in the constitutional framework(Canada (Prime Minister) v. Khadr, 2010 SCC 3, [2010] 1 S.C.R. 44 [Khadr]). More to the point, however, is the fact that thisargument, at least as framed before us, glosses over a recurring theme in constitutional jurisprudence; seldom do courts supply thesolution when legislation has been found unconstitutional.

Declarations are frequently suspended in order to allow the legislature time tocraft a constitutionally compliant response (see, for example, Schachter v. Canada, (SCC), [1992] 2 S.C.R. 679, 93D.L.R. (4th) 1 at 722-725; R. v. Demers, 2004 SCC 46, [2004] 2 S.C.R. 489 at paras. 60 and 66; Bedford at paras. 165 and 169; Carter atpara. 128; Anne M. Turley and Zoe Oxaal, “The Significance of R v. Albashir in the Evolution of Constitutional Remedies” (2023) 108S.C.L.R. (2d) 139). [49] The need for caution in characterizing remedies as non-justiciable is reflected in Mathur v.

His Majesty the King in Right of Ontario,2023 ONSC 2316, 480 D.L.R. (4th) 444 [Mathur 2023]. There, the Court found that what constitutes a science-based GHG reductiontarget and a stable climate system could be established through expert evidence, as they are based on a globally recognized body ofscience (Mathur 2023 at para. 123). Compare, as well with Cambie Surgeries Corporation v.

British Columbia (Attorney General), 2020BCSC 1310, 333 A.C.W.S. (3d) 540 where the Court considered what constituted a reasonable wait time for health care, an equallymulti-layered, complex melange of financial, medical, policy and management issues (at paras. 8-10, 1736-1806). [50] There is also a relationship between the question of whether there is a Charter breach and whether the requested remedies are viable.It may be only when the nature, extent and source of the violation is identified that the appropriateness of the remedy can be assessed.

AsKhadr demonstrates, sometimes there may be no remedy to be enforced, but a declaratory remedy may be granted nonetheless (see alsoFeldman J.A. in Tanudjaja at para. 85). Declarations may serve to vindicate rights; Khadr is but one example of many (see also Ewert v.Canada, 2018 SCC 30, [2018] 2 S.C.R. 165 at para. 81; Operation Dismantle at 457; David Suzuki Foundation v.

Canada (Fisheriesand Oceans), 2010 FC 1233, [2012] 3 F.C.R. 136 at para. 202, aff’d 2012 FCA 40, [2013] 4 F.C.R. 155). [51] Even if some of the remedies sought push the boundaries of the court’s competence, a claim should not be characterized, a priori, asnon-justiciable. Overly focusing on remedies at the justiciability stage may place "“undue and unwise limits”" on judicial oversight ofthe law (Lorne Sossin, “The Unfinished Project of Roncarelli: Justiciability, Discretion and the Limits of the Rule of Law” (2010) 55:3McGill L.J. 661 at 686).

As a practical matter, remedies are often amended in the course of the litigation and judges are required, whengranting constitutional remedies, to exercise a principled discretion (Ontario (Attorney General) v. G, 2020 SCC 38, 451 D.L.R. (4th)541 at paras. 90-99). The remedies must be tailored to the breach, if a breach is ultimately found. [52] The Federal Court’s perspective on remedies was understandably coloured by the broad and diffuse scope of the claims (La RoseReasons at para. 50, Misdzi Yikh Reasons at para. 73).

For this reason, perhaps, the Court did not consider the declarations sought orassess their viability against the jurisprudence. The Federal Court characterized the remedies as overly prescriptive, but simultaneously as

vague and devoid of meaning. These criticisms are, in part, well-deserved. But they do not justify a pre-emptive decision to foreclose the possibility of remedies tailored to the breach. VI. Public trust doctrine [ 53 ] In their statement of claim, the youth appellants assert that Canada has breached its duty to preserve and protect inherently public resources—bodies of water, the air, and the permafrost—so that current and future generations may access, use, and enjoy these resources.

They describe Canada’s obligations in this regard as originating from a " “public trust doctrine” " (youth appellants’ statement of claim at para. 239). [ 54 ] Manson J. concluded that this claim had no reasonable prospect of success as " “there [was] no legal foundation to suggest that the public trust doctrine, as described by the [youth appellants], discloses a reasonable cause of action” " ( La Rose Reasons at para. 87 ).

Manson J. also noted that " “the public trust doctrine is a concept that Canadian Courts have consistently failed to recognize” " and stated that this doctrine " “does not exist in Canadian law” " ( La Rose Reasons at para. 93 ). [ 55 ] The youth appellants argue that the doctrine’s lack of prior recognition by Canadian courts does not necessarily indicate that their public trust claims were doomed to fail.

Further, they say that the Supreme Court in Canfor expressly left open the possibility that a public trust doctrine could be advanced, and that an extension of the common law in these circumstances would accord with a principled and incremental legal development of the law ( Paradis Honey Ltd. v.

Canada (Attorney General) , 2015 FCA 89 , [2016] 1 F.C.R. 446 at paras. 116-117 , leave to appeal to SCC refused, 36471 (29 October 2015) [ Paradis Honey ]). [ 56 ] The contours of the public trust doctrine as pleaded by the appellant are imprecise and fluid; the doctrine is described as a trust-like duty, an aspect of the Crown’s parens patriae jurisdiction, a fiduciary obligation and an unwritten constitutional principle. The doctrine is said to impose specific, enforceable obligations on Canada to preserve and protect public resources such as the air, the atmosphere, navigable waters and territorial seas.

The doctrine would require Canada to exercise continuous supervision and control over these resources, to protect the public rights to their use and enjoyment and to ensure their integrity for future generations. The youth appellants say that Canada owes these obligations to its citizens, who, as beneficiaries, can enforce the doctrine where Canada has not lived up to its responsibilities. [ 57 ] I disagree that Manson J. erred as alleged by the youth appellants.

The motions judge understood the jurisprudence with respect to both motions to strike and the public trust doctrine and applied it correctly. [ 58 ] Manson J.’s conclusion was shaped not by the novelty of the public trust claims ( La Rose Reasons at paras. 81-84 ), but by his analysis of two decisions dealing with public rights vested in the Crown, Canfor and Burns Bog ( La Rose Reasons at paras. 88-92 ).

Measuring the youth appellants’ public trust claims against the existing case law, Manson J. identified the claims as resting on an entirely non-existent cause of action and accordingly determined that the claims had no reasonable prospect of success ( La Rose Reasons at paras. 92-94 , citing Atlantic Lottery at para. 19 ). I agree with the judge’s reasons. [ 59 ] Canfor establishes that the Crown may bring a tort action as a " “representative of the public to enforce the public interest in an unspoiled environment” " ( Canfor at para. 64 ).

Binnie J. determined that although the Crown was limited to suing in its capacity as a private party as landowner of the damaged forests, the Attorney General may have standing to bring an action on behalf of the general public in a proper case based on the parens patriae responsibilities of the Crown ( Canfor at paras. 76 and 81 ).

Binnie J. stated in obiter that this standing would raise important policy questions relating to " “the Crown’s potential liability for inactivity in the face of threats to the environment” " and " “the limits to the role and function and remedies available to governments taking action on account of activity harmful to public enjoyment of public resources” " , but did not comment on the merits of these questions ( Canfor at paras. 81-82 ). [ 60 ] The Attorney General’s presumptive standing to appear and act in the public interest, as established in Canfor , cannot be equated to a substantive, enforceable obligation owed to the public at large.

The public trust doctrine provides an affirmative basis for the Crown to act; it is an entirely different proposition to say that the Crown can be compelled to fulfill some form of a parens patriae jurisdiction which would be defined by the court. [ 61 ] There are also a host of conceptual problems in imposing a fiduciary or trust-like obligation on the Crown, most notably the difficulty of reconciling the obligations of a trustee or fiduciary to act solely in the best interests of an identified person or group with the principles of Westminster parliamentary democracy.

Parliament and Cabinet must act in what they consider to be the best interests of Canada as a whole ( Alberta v. Elder Advocates of Alberta Society , 2011 SCC 24 , [2011] 2 S.C.R. 261 at paras. 44 and 50 ), and in accordance with the Constitution Act, 1867 , which places most lands under provincial responsibility. This Court in Burns Bog interpreted Canfor to leave open the possibility that the public trust doctrine could apply, but confirmed that it would not apply where the Crown did not own the land in question ( Burns Bog at paras. 44, 46-47 ).

The youth appellants’ claim is not targeted to land owned by Canada. [ 62 ] Accepting that a public trust doctrine may some day be recognized in Canadian courts, I agree with the motions judge that " “[ Canfor and Burns Bog ] do not approach the breadth of the rights and actionable interests that the [youth appellants] claim could exist at common law” " ( La Rose Reasons at para. 92 ).

Neither Canfor nor Burns Bog support a claim that Canada has an affirmative, trust-like duty to protect public resources in the way that the youth appellants desire, no matter how sound their objectives or how genuine their motives. The principles that inform when trust-like duties may be imposed on the Crown are narrow. The public trust claim was therefore properly struck. VII. Peace, order and good government / The general power [ 63 ] The Dini Ze’ initially claimed that Canada’s power to make laws for the peace, order and good government of Canada under

section 91 of the Constitution Act, 1867 imposed a positive obligation on Parliament to enact laws that effectively reduced its GHG emissions. In

response to Canada’s motion to strike, the Dini Ze’ sought leave to amend their statement of claim. They now describe

section 91 as aprovision that "“limits [Canada’s] powers to pass laws that are inconsistent with its constitutional duty to the [Dini Ze’] and with itsinternational commitments to keep global warming to well below 2°C”" (Dini Ze’s amended statement of claim at para. 85). [64] McVeigh J. rejected the Dini Ze’s proposed amendments and struck their claim under

section 91 of the Constitution Act, 1867without leave to amend (Misdzi Yikh Reasons at para. 114). She concluded that their proposed amendments presented only "“asemantical change”" that did not cure their characterization of the general power as a power dictating that the government enact specificlaws (Misdzi Yikh Reasons at para. 46). [65] The Dini Ze’ argue that McVeigh J. misinterpreted their proposed amendments as imposing a positive duty on Canada, instead of alimitation on what Canada may legislate. They also say that their claim has a reasonable prospect of success given two UK decisions (R.(Bancoult) v.

Secretary of State for Foreign and Commonwealth Affairs, [2001] QB 1067 [Bancoult (No. 1)] and R. (Bancoult) v.Secretary of State for Foreign and Commonwealth Affairs, [2008] UKHL 61 [Bancoult (No. 2)]). [66] These arguments are unpersuasive and I agree with the reasoning of McVeigh J. [67] Decades of jurisprudence have described the contours of the general power under

section 91: it serves as an important residualsource of federal jurisdiction. The purpose of the general power is to ensure that every possible subject of legislation belongs to one orother of the federal Parliament or the provincial Legislatures. In this way, the general power facilitates the division of powers byauthorizing Parliament to act where there are gaps in the distribution of powers, in matters of national concern, or in the face ofemergencies (References re Greenhouse Gas Pollution Pricing Act, 2021 SCC 11, 455 D.L.R. (4th) 1 at para. 115 [GGPPA References];R. v.

Malmo-Levine, 2003 SCC 74, [2003] 3 S.C.R. 571 at para. 72; Ontario Hydro v. Ontario (Labour Relations Board), (SCC), [1993] 3 S.C.R. 327, 107 D.L.R. (4th) 457 at 379; Labatt Breweries of Canada Ltd. v. Attorney General of Canada, (SCC), [1980] 1 S.C.R. 914, 110 D.L.R. (3d) 594 at 944-945; Re: Anti-Inflation Act, (SCC), [1976] 2 S.C.R.373, 68 D.L.R. (3d) 452 at 403; Peter W. Hogg and Wade K. Wright, Constitutional Law of Canada, 5th ed.

Supp., vol. 1 (Toronto:Thomson Reuters, 2021) (loose-leaf updated 2022, release 1), ch. 17 at 17-2). [68] The Dini Ze’—pointing to Canada’s enactment of legislation that effectively licenses GHG emissions and its approvals of highGHG-emitting projects by way of Orders in Council—claim that Canada is legislating outside of its constitutional authority by notpromoting peace, order and good government.

Despite their argument that their proposed claim under the general power focuses on alimitation rather than a duty, the Dini Ze’ have nevertheless framed the claim in a way that rests on a requirement that Parliamentlegislate in a particular manner. [69] There is no anchor for this proposition in the 156 years of Confederation.

Section 91 is a source of Parliament’s legislative power,not a limit; it is an unqualified grant of legislative power, not an obligation. The general power is not an overarching obligation thatrequires Parliament to maintain a standard of "“peace, order and good government of Canada”" with every legislative decision. Whetherthe Dini Ze’s argument is cast as a positive duty or a limit on Parliament’s power is a distinction without a difference; the substance ofthe argument is that

section 91 requires Parliament to enact laws that achieve what the judiciary determines to be necessary for the peace,order and good government of the country. [70] As noted earlier, the appellants rely on two decisions from UK courts to support their

interpretation of

section 91. [71] In Bancoult (No. 1), the UK’s Queen’s Bench Division was tasked with determining whether an ordinance which prohibited theIndigenous people born in the British Indian Ocean Territory from returning to and residing in their homeland was unlawful for upsettingthe "“peace, order and good government”" of the territory.

The Queen’s Bench decided that the executive’s power to legislate for the"“peace, order and good government”" of the British Indian Ocean Territory did not extend so far as to permit the executive to removethe inhabitants of the territory for political reasons (Bancoult (No. 1) at 1104). [72] In Bancoult (No. 2), however, the UKHL upheld an Order in Council similar to the ordinance found to be ultra vires in Bancoult(No. 1). Lord Hoffman of the UKHL expressly disagreed with the Queen’s Bench’s

interpretation of "“peace, order and goodgovernment”" at para. 50): [T]he words “peace order and good government” have never been construed as words limiting the power of a legislature.Subject to the principle of territoriality implied in the words “of the Territory”, they have always been treated as apt toconfer plenary law-making authority...

The courts will not inquire into whether legislation within the territorial scope of thepower was in fact for the “peace, order and good government” or otherwise for the benefit of the inhabitants of the Territory.So far as Bancoult (1) departs from this principle, I think that it was wrongly decided. I note that the UKSC upheld the UKHL’s decision in Bancoult (No. 2) in R (on the application of Bancoult (No. 2)) v.

Secretary of Statefor Foreign and Commonwealth Affairs, [2016] UKSC 35. [73] The Bancoult decisions do not therefore assist the appellants. [74] In any event, constitutional analysis is principally informed by Canadian jurisprudence, which is in turn shaped by our political andsocial history and only draws upon decisions of foreign courts or principles of international or comparative law in exceptionalcircumstances (Quebec (Attorney General) v. 9147-0732 Québec inc., 2020 SCC 32, [2020] 3 S.C.R. 426 at paras. 43-47).

This practiceis driven by the obvious reality that measures adopted in other contexts may be of scant relevance, a point particularly apposite in respectof the Bancoult decisions. [75] I agree with McVeigh J.’s conclusion that the UK cases relied upon by the Dini Ze’ were not instructive (Misdzi Yikh Reasons atpara. 40) and her conclusion that "“the POGG power has never been used in such a way, and… that even this novel attempt must fail”"(Misdzi Yikh Reasons at para. 46). I would accordingly uphold her decision to strike this part of the claim without leave to amend.

VIII.

Section 15 of the Charter [76] Climate change is having a dramatic, rapidly unfolding effect on all Canadians and on northern and Indigenous communities inparticular. In the GGPPA References, the Supreme Court recognized that climate change has had a "“particularly serious effect”" onIndigenous peoples and Indigenous territories, "“threatening the ability of Indigenous communities in Canada to sustain themselves andmaintain their traditional ways of life”" (GGPPA References at paras. 11-12, 187, 206).

Canada accepts this, noting that "“[g]lobalclimate change is… not a distant problem, but one that is happening now and that is having very real consequences on people’s lives”"(Canada’s memorandum of fact and law in Misdzi Yikh appeal at para. 1). It is also beyond doubt that the burden of addressing theconsequences will disproportionately affect Canadian youth. [77] The question is whether it is reasonably arguable that this reality falls within the scope of

section 15. The appellants’ case is thatclimate change affects them disproportionately and that the legislation is not sufficiently robust to address this inequality. Their case is,therefore, one of adverse effect discrimination and whether the law has a disproportionate impact on members of groups protected on thebasis of an enumerated or analogous ground. [78] Claims under

section 15 of the Charter are assessed under a two-part test. [79] The court is to first determine whether the law or state action creates a distinction based on an enumerated or analogous ground. Ifthe law does not do this on its face, claimants must establish that a law has a disproportionate impact on members of a protected group(Fraser v. Canada (Attorney General), 2020 SCC 28, 450 D.L.R. (4th) 1 [Fraser] at para. 52).

Second, the court is to assess whether thelaw or state action imposes burdens or denies a benefit in a manner that perpetuates, reinforces, or exacerbates some disadvantageexperienced by the group, either systemically or historically (R. v. Sharma, 2022 SCC 39, 420 C.C.C. (3d) 1 at para. 28 [Sharma];Fraser at paras. 27 and 77). [80] Claims under

section 15 may be directed at the state’s conduct in implementing a law or policy, as well as the law or policy itself(Little Sisters Book and Art Emporium v. Canada (Minister of Justice), 2000 SCC 69, [2000] 2 S.C.R. 1120 at para. 125; Withler v.Canada (Attorney General), 2011 SCC 12, [2011] 1 S.C.R. 396 at para. 30 [Withler]; Quebec (Attorney General) v. Alliance dupersonnel professionnel et technique de la santé et des services sociaux, 2018 SCC 17, [2018] 1 S.C.R. 464 at para. 25 [Alliance]; Fraserat paras. 27 and 50). Where the state has chosen to provide benefits or impose burdens on the general population, the state is obligated todo so in a non-discriminatory manner under

section 15. [81]

Section 15 is directed toward substantive equality, and ensures that legal benefits are provided and obligations imposed withoutdiscrimination on a protected ground (Alliance at para. 25; Fraser at para. 27).

Section 15 does not, however, impose "“a freestandingpositive obligation on the state to enact benefit schemes to redress social inequalities”" (Alliance at para. 42). In addition, the state is freeto address inequality incrementally (Sharma at para. 64; Auton (Guardian ad litem of) v. British Columbia (Attorney General), 2004SCC 78, [2004] 3 S.C.R. 657 at para. 41 [Auton]; Eldridge v. British Columbia (Attorney General), (SCC), [1997] 3S.C.R. 624, 151 D.L.R. (4th) 577 at paras. 72-73; Alliance at para. 42). [82] The adverse or disproportionate effect that climate change is having on the appellants is not the kind of adverse effect that

section 15is to address. I accept the argument that the intergenerational considerations associated with climate change raise profound moral, socialand economic questions; but, save as I will discuss later (at paras. 119-125) intergenerational equity is not within the scope of

section 15,as the law currently stands. [83] The underlying rationale for this is rooted in the separation of powers; if courts could adjudicate

section 15 claims that allegediscrimination caused by future inequalities, the judiciary would effectively be participating in the policy choices around resourceallocation, the domain of the legislature and executive (Sharma at para. 63). [84] I understand the youth appellants’ argument that, as they have no vote or no voice in these decisions, the reach of

section 15 ought tobe extended. This, however, would be an unprecedented application of

section 15, and not the kind of gradual, incremental change bywhich the law evolves. [85] Age as a protected ground occupies a unique status, as age is universal: an individual at any given age has personally experienced allearlier ages, and expects to experience later ages. As La Forest J. noted in McKinney v.

University of Guelph, [1990] 3 S.C.R. 229, (SCC), "“while we must guard against laws having an unnecessary deleterious impact on the aged based on inaccurateassumptions about the effects of age on ability, there are often solid grounds for importing benefits on one age group over another in thedevelopment of broad social schemes and in allocating benefits”" (at 297). [86] Choices made by Parliament or the executive will, of necessity, affect different generations differently.

Decisions made today withrespect to health care spending may, for example, largely benefit older Canadians, or decisions to invest in major infrastructure projectsmay largely benefit younger generations. Broad policy decisions by a government, such as the degree to which debt should be incurred,will affect different generations differently. As distinct from their

section 7 claims, the true nature of the appellants’ equality argument isabout how the legislation will affect them when they are older. [87] Notwithstanding the above, the international legal community is moving towards the recognition of youth climate rights and thepromotion of intergenerational equity.

A recent report from the United Nations Committee on the Rights of the Child urged states to takeimmediate action to address environmental degradation and climate change, as they challenge children’s rights to life, survival, anddevelopment (General comment No. 26 (2023) on children’s rights and the environment, with a special focus on climate change, United Nations Committee on the Rights of the Child, 93rd Sess., U.N. Doc. CRC/C/GC/26 (2023) at paras. 63-67).

While Canada has ratifiedthe Convention on the Rights of the Child and the Convention has been used many times by courts in interpreting domestic legislation(see, for example, M.M. v. United States of America, 2015 SCC 62, [2015] 3 S.C.R. 973 at para. 148, citing Baker v. Canada (Minister ofCitizenship and Immigration), [1999] 2 S.C.R. 817, (SCC) at para. 71), this does not yet create a place in theframework under

section 15 that would allow the youth appellants’ claim to proceed.

[88] I would therefore uphold the motions judges’ decisions to strike the

section 15 claims without leave to amend. IX.

Section 7 of the Charter [89]

Section 7 of the Charter states that "“[e]veryone has the right to life, liberty and security of the person and the right not to bedeprived thereof except in accordance with the principles of fundamental justice.”" To establish a breach of

section 7, then, claimantsmust show that the "“law interferes with, or deprives them of, their life, liberty or security of the person”", and that this deprivation "“isnot in accordance with the principles of fundamental justice”" (Carter at para. 55; see also Chaoulli at para. 109). [90] Claimants must also demonstrate a causal connection between the impugned action or law and the prejudice they have suffered(Bedford at para. 75).

However, claimants need not demonstrate that the state alone is accountable for the prejudice they have suffered(Bedford at para. 76): A sufficient causal connection standard does not require that the impugned government action or law be the only or thedominant cause of the prejudice suffered by the claimant, and is satisfied by a reasonable inference, drawn on a balance ofprobabilities (Canada (Prime Minister) v. Khadr, 2010 SCC 3, [2010] 1 S.C.R. 44, at para. 21).

A sufficient causalconnection is sensitive to the context of the particular case and insists on a real, as opposed to a speculative, link. [91] While I will return to the question of causal connection at the conclusion of these reasons when I discuss sufficiency of thepleadings, I want to foreshadow that there is a distinction between sufficient pleading of a causal link and a pre-emptive determination offact that such a causal link can never be established. Here, the motions judges based their decisions on a pre-emptive determination offact and in so doing erred. Characterization of claims/Positive rights [92]

Section 7 and the associated jurisprudence does not confer a right to any particular legislative regime that guarantees or maximizesthe life, liberty and security of the person; rather,

section 7 protects against the deprivation of these interests. Accordingly, the state hasnot, so far, been required to "“act affirmatively to ensure that each person enjoys a minimum of life, liberty and security of the person”"(Kreishan at para. 136; Gosselin at para. 81). To engage

section 7, courts have required more than a harm that could be alleviated bystate action—there must be a deprivation arising from the state action itself. [93] It can be discerned from the history of the

section 7 jurisprudence that the Supreme Court, indeed all courts, are cautious aboutopening the door to positive rights claims. Positive rights challenges have been dismissed in a multiplicity of contexts in diverse foraacross Canada (PHS at para. 92; Bedford at paras. 60 and 75; Carter at para. 55; Chaoulli at paras. 103-104; Emmett Macfarlane,“Dialogue, Remedies, and Positive Rights: Carter v Canada as a Microcosm for Past and Future Issues Under the Charter of Rights andFreedoms” (2017) 49 Ottawa L. Rev. 107 at 121).

They have been dismissed in actions concerning social welfare benefits (Masse v.Ontario (Minister of Community and Social Services), 134 D.L.R. (4th) 20, (ONSCDC) at paras. 73 and 172;McMeekin v. Government of the Northwest Territories, 2010 NWTSC 27, 209 C.P.R. (2d) 243 at paras. 27-31; Lacey v. BritishColumbia, (BCSC), 1999 CarswellBC 3078 (WL Can) at paras. 4-6; Conrad v. Halifax (County), (NS SC), 124 N.S.R. (2d) 251, 345 A.P.R. 251 (NSSC) at paras. 90-96), health care (Chaoulli at para. 104; Toussaint v.

Canada(Attorney General), 2011 FCA 213, [2013] 1 F.C.R. 374 at para. 77, leave to appeal to SCC refused, 34446 (5 April 2012)), autismprograms (Sagharian v. Ontario (Education), 2008 ONCA 411, 172 C.P.R. (2d) 105 at paras. 52 and 57, leave to appeal to SCC refused,32753 (4 December 2008); Wynberg v. Ontario (2006), (ON CA), 269 D.L.R. (4th) 435, 82 O.R. (3d) 561 (ONCA)at paras. 219-220), witness protection (John Doe v. Ontario, 162 C.R.R. (2d) 186, 2007 CarswellOnt 6478 (WL Can) (ONSC) at para.113, aff’d 2009 ONCA 132), unlawful detention (Good v.

Toronto Police Services Board, 2013 ONSC 3026, 43 C.P.C. (7th) 225 at para.143), refugee asylum claims (Kreishan at paras. 135-141), and climate change (Trans Mountain Pipeline ULC v. Mivasair, 2019 BCSC50, 427 C.R.R. (2d) 212 at para. 68). [94] Two recent cases of the British Columbia Court of Appeal exemplify this approach. [95] Scott v. Canada (Attorney General), 2017 BCCA 422, 417 D.L.R. (4th) 733 [Scott] dealt with a

section 7 claim brought by membersof the Canadian Forces which alleged that the government’s compensation scheme for injured veterans was insufficient. The Courtstruck the claim since there was no deprivation imposed by the government—the legislation was just a "“benefit-conferring program”"(Scott at para. 89). More recently, the British Columbia Court of Appeal struck a claim brought by an individual who alleged that theMinister of Health’s failure to consider his application to access a medical drug violated his

section 7 rights. Willcock J.A., writing forthe Court, pointed to the consistent line of jurisprudence holding that a government’s failure to provide a financial benefit alone cannotground a

section 7 claim (Chung v. British Columbia (Minister of Health), 2023 BCCA 294, 2023 CarswellBC 2045 (WL Can) at paras.65-67). [96] This does not mean that the door to positive rights under

section 7 is closed. As early as 2000, the Supreme Court recognized therole of

section 7 in reflecting and safeguarding the public’s evolving values (Blencoe v. British Columbia (Human Rights Commission),2000 SCC 44, [2000] 2 S.C.R. 307 at para. 188, per LeBel J): We must remember though that s. 7 expresses some of the basic values of the Charter. It is certainly true that we must avoidcollapsing the contents of the Charter and perhaps of Canadian law into a flexible and complex provision like s. 7. But itsimportance is such for the definition of substantive and procedural guarantees in Canadian law that it would be dangerous tofreeze the development of this part of the law.

The full impact of s. 7 will remain difficult to foresee and assess for a longwhile yet. Our Court should be alive to the need to safeguard a degree of flexibility in the

interpretation and evolution of s. 7of the Charter. [97] In 2002, in Gosselin, McLachlin C.J. endorsed LeBel J.’s observation. There, she noted that "“[o]ne day s. 7 may be interpreted to

include positive obligations”", and that "“[i]t would be a mistake to regard s. 7 as frozen, or its content as having been exhaustivelydefined in previous cases”" (Gosselin at para. 82). The Chief Justice elaborated that the question of whether positive rights arise undersection 7 is one that courts must assess based on the case before them (Gosselin at para. 82): The question therefore is not whether s. 7 has ever been — or will ever be — recognized as creating positive rights.

Rather,the question is whether the present circumstances warrant a novel application of s. 7 as the basis for a positive stateobligation to guarantee adequate living standards. [98] Rumblings of positive rights have continued to sound since Gosselin. The Court of Queen’s Bench of Alberta, for example,dismissed a claim under

section 7 challenging inadequate workers compensation benefits, but noted that interference with economicrights alone could ground a positive rights claim if it were to result in "“serious stress, stigma and anxiety that substantially affect aperson’s security of the person”" (Schulte v. Alberta (Appeals Commission for Alberta Workers' Compensation), 2015 ABQB 17, 605A.R. 210 at para. 130, aff’d on appeal (without comment on this point) at 2016 ABCA 304, [2017] 3 W.W.R. 694). This Court has aswell acknowledged the possibility that

section 7 may some day impose positive obligations on the state, and noted that this may arise inthe context of climate litigation (Kreishan at para. 139). [99] There is also a significant body of academic analysis supporting the recognition of positive rights under

section 7. Martha Jackmanand Bruce Porter, for example, advocate for the recognition of positive rights under the Charter, as it would "“ensur[e] effectiveimplementation of international human rights through the

interpretation and application of domestic law”", and would allow "“Canada’slegal culture [] to better align with the views and expectations of civil society and Indigenous peoples”" (Martha Jackman & BrucePorter, “Social and Economic Rights in Canada” in Peter Oliver, Patrick Macklem, & Nathalie Des Rosiers (eds.), The Oxford Handbookof the Canadian Constitution (New York, Oxford University Press, 2017) at 860; see also Martha Jackman, “Charter Remedies forSocio-Economic Rights Violations: Sleeping Under a Box?”, in Robert J.

Sharpe and Kent Roach (eds.), Taking Remedies Seriously(Ottawa: Canadian Institute for the Administration of Justice, 2010) at 284-285). [100] However, the recognition of positive rights under

section 7 is not without critics. James Hendry, for example, argues that thesection 7 framework does not lend itself to positive rights, as the rights protected under

section 7 are inherently non-comparative andmust be determined "“at large”" (James Hendry, “Section 7 and Social Justice” (2009-2010) 27 N.J.C.L. 93 at 106). Critics also contendthat courts are simply not competent to adjudicate the complex policy issues that would follow the recognition of positive rights undersection 7 (Colin Feasby, David DeVlieger & Matthew Huys, “Climate Change and the Right to a Healthy Environment in the CanadianConstitution” (2020) 58:2 Alta. L.

Rev. 213 at 239). [101] Regardless of which side of the debate is to be preferred, there is one point on which there is agreement: the line between positiveand negative rights is at times difficult to draw. The traditional distinction asserts that positive claims require positive governmentalaction, whereas negative claims require the government to refrain from acting in some way (Toronto (City) v. Ontario (AttorneyGeneral), 2021 SCC 34, 462 D.L.R. (4th) 1 at para. 20 [Toronto (City)]).

However, some rights have both positive and negativeelements; others have gone further in writing that "“no right can exist without some form of corresponding obligation to do or not dosomething”" (Nathalie J. Chalifour & Jessica Earle, “Feeling the Heat: Climate Litigation Under the Canadian Charter’s Right to Life,Liberty, and Security of the Person” (2018) 42 Vt. L. Rev. 689 at 742). [102] Many rights exist on the margins. Take, for example, the right to a fair trial, which requires the state to refrain from breachingcertain procedural guarantees, but also to provide an adequate court system.

Consider also the right to accessibility: an individual withdisabilities requires an assistive device, but only because the state has constructed inaccessible programs and infrastructure. The right atissue appears positive, but it was only brought about because the state failed to refrain from breaching existing negative rights. (SeeSandra Fredman, “Human Rights Transformed: Positive Duties and Positive Rights”, [2006] P.L. 498 at 502; see also Vasuda Sinha,Lorne Sossin, & Jenna Meguid, “Charter Litigation, Social and Economic Rights & Civil Procedure” (2017) 26:3 J. L. & Soc.

Pol’y 43 at60). [103] This at times false dichotomy has been recognized judicially. Abella J.’s dissent in Toronto (City) noted that "“[a]ll rights havepositive dimensions since they exist within, and are enforced by, a positive state apparatus”" and that "“[a]ppropriate verbalmanipulations can easily move most cases across the line”" (Toronto (City) at para. 153, citing S. F. Kreimer, “Allocational Sanctions:The Problem of Negative Rights in a Positive State” (1984), 132 U. Pa. L. Rev. 1293, at 1325); put otherwise, a right may be seen asnegative or positive depending simply on the perspective taken.

The majority in Toronto (City) relied on the distinction between stateaction and state restraint for the purposes of their freedom of expression analysis, but they too acknowledged that the distinction betweenpositive and negative entitlements is "“not always clearly made, nor… always helpful”" (Toronto (City) at para. 20, citing Haig v.Canada, [1993] 2 S.C.R. 995, (SCC)). [104] Mactavish J. (as she then was) acknowledged the difficulty in characterizing a claim as either "“exclusively positive or exclusivelynegative”" in the context of a

section 7 analysis in Canadian Doctors for Refugee Care v. Canada (Attorney General), 2014 FC 651,[2015] 2 F.C.R. 267 at para. 520 [Canadian Doctors]. Mactavish J. noted that "“section 7 jurisprudence has demonstrated that the factthat a particular claim may involve a request that the government spend money in a particular way is not necessarily fatal to the claim”"(Canadian Doctors at para. 522). Indeed, the Supreme Court has found

section 7 rights violations within this blurred zone. For example,the right to state-funded counsel was recognized in New Brunswick (Minister of Health and Community Services) v. G. (J.), [1999] 3S.C.R. 46, (SCC); and the right to be exempted from prohibitive legislation in PHS. Both may be conceptualizeddepending on the perspective taken, as positive rights claims. [105] Here, the motions judges erred in striking the claims on the basis that they were positive rights claims. The Dini Ze’s pleadingsspeak to a direct deprivation of their security of the person.

They describe, in considerable detail, the effects of climate change on theirfood security, culture and economies. They attribute this to specific state action including deficient legislative standards and permissivelicensing of GHG-emitting projects. Their claim speaks to a current and ongoing deprivation. [106] The youth appellants’ claim, in contrast, is less specific than that of the Dini Ze’. The youth appellants’ claim speaksprospectively; it speaks to the consequences of permissive regulation in the future, and has at its foundation the premise that the

plaintiffs have a Charter protected right to live in a world with a stable climate system. However, the youth appellants’ claim, read generously, does refer to deprivations: Canada has consistently missed the emissions targets it has set for itself under the Paris Agreement (enshrined domestically in the Canadian Net-Zero Emissions Accountability Act ) and is similarly on track to miss its future emissions targets. Canada’s failures are deprivations in that they deprive the appellants of the fruits of Canada’s legislated commitments and compromise the appellants’

section 7 interests. [ 107 ] In Leroux v. Ontario , 2023 ONCA 314 , 481 D.L.R. (4th) 502 [ Leroux ] the Ontario Court of Appeal allowed a

section 7 claim to proceed to trial, even though it " “sail[ed] close to asserting a positive constitutional obligation” " . The claimants in Leroux alleged that the government’s inadequate provision of supports for persons with developmental disabilities violated

section 7 . The Court distinguished the claim from other failed positive rights claims under

section 7 since the claimants in this case had already been approved for government support which was effectively denied in its implementation. [ 108 ] In allowing the claim to go forward, the Court cited the principle that claims should be struck with care, noting that this principle may apply with particular force " “for novel Charter claims that explore the scope of a right, as such claims often require a trial and an evidentiary record to fully understand the nature of the impugned state action and the harms experienced by claimants” " ( Leroux at para. 86 , citing Lorne Sossin and Gerard J.

Kennedy, “Justiciability, Access to Justice and the Development of Constitutional Law in Canada”, (2017) 45:4 Fed. L. Rev. 707, at 719). [ 109 ] I return at this point to where I began. The claim of a right to a healthy and livable environment, and the legislative sanctioning of something less, explores the scope of

section 7 and tests its boundaries. The argument is novel, but it is not doomed to fail. Courts should be cautious in striking claims at an early stage. It is trite law that novel but arguable claims should be allowed to proceed so as to not inhibit the development of the common law ( Imperial Tobacco at para. 21 ). The law is not static and unchanging—actions that were deemed hopeless yesterday may succeed tomorrow. It is for this reason that courts must be cautious about striking claims and err on the side of allowing novel but arguable claims to proceed. [ 110 ] The necessary element of deprivation in

section 7 has been found in circumstances where legislation or executive actions create or exacerbate a risk to life, liberty or security of the person ( Bedford ; PHS ). In essence, this is the theory, or one of the theories, that underlies the appellants’ case, and the analogy to the case at bar is obvious. The appellants argue that the legislation and Orders in Council, permitting, as they do, GHG emissions, deprive them of their

section 7 interests. Just as the prostitution provisions of the Criminal Code made the lives of the sex-workers more precarious, so too does the suite of federal laws challenged here. The Federal Court therefore erred in reasoning that the appellants’

section 7 claims were positive rights claims and accordingly had no reasonable prospect of success. [ 111 ] Recently, in Mathur 2023 , the Ontario Superior Court dismissed a

section 7 challenge to a target set pursuant to Ontario legislation that seeks a 30% reduction in GHG emissions from 2005 levels by 2030. The applicants argued that this target was not high enough to avoid the severe effects of climate change. The Court ruled that, even if the target had deprived the applicants of their rights to life, liberty and security of the person, these deprivations would not have been contrary to the principles of fundamental justice ( Mathur 2023 at para. 171).

More specifically, the Court found that Ontario’s target was not arbitrary in relation to the law’s objective of reducing GHG emissions, nor was it disproportionate relative to the law’s objective of reducing GHG emissions. The applicants in fact agreed with the legislation’s objective, and instead argued that Ontario should pursue its goal of addressing climate change more aggressively ( Mathur 2023 at paras. 162 and 171). [ 112 ] Importantly for the purpose of these reasons, the Court arrived at this conclusion after a trial. The question there was whether the applicants had in fact made out their

section 7 claim on the merits, not whether a

section 7 claim of this nature should be allowed to be argued. The Court was able to apply the elements of a

section 7 analysis—nexus, causation, deprivation as well as arbitrariness and proportionality. [ 113 ] The Federal Court erred in presumptively concluding that a causal relationship between the legislation and the deprivation of a

section 7 interest is " “manifestly incapable of being proven.” " As the Mathur 2023 decision demonstrates, the arguments are not fanciful or incapable of being assessed against a body of evidence. It is sufficient to say, for the purposes of these appeals, that while the challenged law or government action need not be the sole or dominant course of the alleged deprivation, there must be a real as opposed to speculative link ( Bedford at para. 76 ). While this link may not be made on the pleadings as they stand, this does not mean that the claim under

section 7 is so doomed to fail that it cannot proceed in any renewed form. I will address this at the conclusion of these reasons. [ 114 ] There is no reason to conclude that harms flowing from climate change and climate-related legislation are manifestly incapable of proof, as did the Federal Court. While the pleadings require amendment, there is a vast body of scientific knowledge dealing with climate change, GHG emissions, and their consequences on human health and the environment. These harms have been acknowledged by the Canadian government itself: the Canadian Net-Zero Emissions Accountability Act states in its

preamble that " “climate change poses significant risks to human health and security” " and that " “the science clearly shows that human activities are driving unprecedented changes in the Earth’s climate” " . The Canadian Net-Zero Emissions Accountability Act goes on to enshrine certain GHG targets, including net-zero emissions for 2050 ( Canadian Net-Zero Emissions Accountability Act , s. 6 ). One of the purposes of the Act is stated in

section 4 to be " “requir[ing] the setting of national targets for the reduction of GHG emissions based on the best scientific information available” " . [ 115 ] I return to Gosselin , where the Court held that a positive rights claim could be advanced in " “special circumstances” " (at para. 83). There is no guidance in the jurisprudence as to what those circumstances might be. The appellants contend that the circumstances before the Court constitute special circumstances warranting a novel application of

section 7 and that the Federal Court erred in closing the door on this argument. [ 116 ] Climate change’s current and potential effects are widespread and grave, they include loss of land and culture, food insecurity, injury and death. In the GGPPA References the Supreme Court noted that climate change is an existential challenge, a threat of the highest order to the country, and to the future of humanity which cannot be ignored ( GGPPA References at para. 167 ). If these do not

constitute special circumstances, it is hard to conceive that any such circumstances could ever exist; however this remains to bedetermined by the trial judge. [117] I have explained the analytical limits of positive/negative rights dichotomy and why the claims before us can be taken to assertelements of both. Subject to what follows, there is, nevertheless, a sufficient pleading of a

section 7 violation in its orthodoxunderstanding to survive a motion to strike. Where novel Charter claims test the boundaries of a right, such claims may require a trial inorder to understand the nature of the legislation, executive action or regulation and the harm experienced by claimants. This is one ofthose cases. [118] This is not to say that all

section 7 claims require a trial; far from it. Pleadings that use

section 7 to address broad, systemic socialproblems detached from a particularized legislative scheme constituting the deprivation, such as in Tanudjaja, remain the proper targetof a motion to strike. Here, in contrast, the deprivations of the

section 7 interests are anchored in legislation, Orders in Council andexecutive action, albeit obscured by an effusive and broad pleading. X. A note on precedent [119] The law cannot remain stagnant. That said, courts must be cautious in spurring its development: too quick and the law becomesunpredictable and capricious, too slow and justice falls behind and loses its relevancy.
