Present: Wagner C.J. and Moldaver, Karakatsanis, Côté, Brown, Rowe, Martin, Kasirer and Jamal JJ. on appeal from the court of appeal for british columbia Taxation — Income tax — Equity — Remedies — Rescission — Taxpayers mistaken about income tax consequences of transactions freely agreed upon — Taxpayers petitioning for rescission of transactions — Whether equitable remedy of rescission available . Two companies implemented a plan to protect corporate assets from creditors without incurring income tax liability. The plan was based in part on

interpretations published by the Canada Revenue Agency (“CRA”) of the attribution rules in s. 75(2) and the inter-corporate dividend deduction in s. 112(1) of the Income Tax Act . It involved the creation of family trusts, to which dividends were paid. After the plans were implemented, the Tax Court of Canada, in another matter, interpreted s. 75(2) differently than was commonly accepted by tax professionals and CRA. CRA reassessed the trusts’ returns and imposed unanticipated tax liability.

The trusts petitioned for the equitable remedy of rescission of the transactions leading to and including the payment of dividends. The chambers judge considered himself bound to follow the Court of Appeal for British Columbia’s decision in Re Pallen Trust , 2015 BCCA 222 , 385 D.L.R. (4th) 499, which had applied the test for equitable rescission stated in Pitt v. Holt , [2013] UKSC 26, [2013] 2 A.C. 108 , to similar transactions, and he allowed the petitions. The Court of Appeal dismissed the Attorney General’s appeals.

Held ( Côté J. dissenting): The appeal should be allowed, the judgments of the Court of Appeal and of the chambers judge set aside and the petitions dismissed. Per Wagner C.J. and Moldaver, Karakatsanis, Brown , Rowe, Martin, Kasirer and Jamal JJ.: Taxpayers should be taxed based on what they actually agreed to do and did, and not on what they could have done or later wished they had done. A determination that equity can relieve a tax mistake is barred by a limiting principle of equity and by principles of tax law stated in Canada (Attorney General) v.

Fairmont Hotels Inc. , 2016 SCC 56 , [2016] 2 S.C.R. 720, and Jean Coutu Group (PJC) Inc. v. Canada (Attorney General) , 2016 SCC 55 , [2016] 2 S.C.R. 670. Accordingly, the trusts are barred from obtaining rescission of the transactions. A court of equity may grant relief where it would be unconscionable or unfair to allow the common law to operate in favour of the party seeking enforcement of the transaction. However, it is a limiting principle and a fundamental premise of equity that it developed to alleviate results under the common law that call for relief as a matter of conscience and greater fairness.

Transactions that do not call for relief as a matter of conscience or fairness are properly outside equity’s domain. There is nothing unconscionable or unfair in the ordinary operation of tax statutes to transactions freely agreed upon. If there is to be a remedy, it lies with Parliament, not a court of equity. Furthermore, the principles of tax law and the prohibition against retroactive tax planning stated in Fairmont Hotels and Jean Coutu preclude any equitable remedy. Unless a statute says otherwise, taxpayers are to be taxed in accordance with the applicable tax statute’s ordinary operation.

Taxpayers may structure their affairs so as to reduce their tax liability but may also be taken as having structured their affairs in such a way that increased their tax liability. Tax consequences do not flow from parties’ motivations or objectives. Rather, they flow from their freely chosen legal relationships, as established by their transactions. A taxpayer should neither

be denied nor judicially accorded a benefit based solely on what they would have done had they known better. The proper inquiry is into what the taxpayer agreed to do and not into whether there is a windfall for the public treasury or a taxpayer. A court may not modify an instrument merely because a party discovered that its operation generates an adverse and unplanned tax liability. These principles are of general application and are not confined to cases where rectification is sought. There is no room for distinguishing Fairmont Hotels or Jean Coutu based upon the particular remedy sought.

A taxpayer is barred from resorting to equity in order to undo or alter or in any way modify a concluded transaction or its documentation to avoid a tax liability arising from the ordinary operation of a tax statute. The principles stated in Fairmont Hotels and Jean Coutu are irreconcilable with the conclusion in Pitt v. Holt that equity can relieve a tax mistake. This conclusion contradicts these principles by maintaining that tax consequences are relevant to deciding whether a party to a voluntary disposition can satisfy the test for rescission. The lower courts therefore erred in relying upon Pitt v. Holt .

Further, the constraint imposed by Parliament upon the Minister to assess a taxpayer in accordance with the facts and the law required CRA to reassess the trusts in light of the Tax Court’s decision. The Minister was bound to apply Parliament’s direction in the Income Tax Act , as interpreted by a court of law, unless and until that

interpretation is judged to be incorrect by a higher court. No unfairness lies in holding the trusts to the consequent tax liabilities of the ordinary operation of the Income Tax Act respecting transactions freely undertaken. Per Côté J. (dissenting): The appeal should be dismissed. Rescission is, in strictly limited circumstances, an available remedy that can be used to unwind transactions that were undertaken on the basis of a mistaken assumption, even if permitting it would effectively relieve the taxpayer from payment of unexpected taxes.

There is disagreement with the majority that Fairmont Hotels and Jean Coutu are dispositive of the case at bar. Although those cases affirmed certain principles of tax law, such as the principle that taxpayers should be taxed based on what they did, not what they wish they had done, and the principle that retroactive tax planning is impermissible, they are not determinative of the availability of rescission in the tax context. Neither Fairmont Hotels nor Jean Coutu generally precludes the availability of equitable remedies in a tax context. Both clarified the test for rectification.

Fairmont Hotels and Jean Coutu stand for the following propositions: if a taxpayer does not meet the test for an equitable remedy, then a court has no discretion to grant that remedy, even if the taxpayer may have to pay taxes unexpectedly; if, however, a taxpayer meets the test for an equitable remedy, then the court may grant it, even if doing so would effectively relieve the taxpayer from payment of the unexpected taxes; and a common intention to limit or avoid tax liability is insufficiently precise to evince an existing prior agreement with definite and ascertainable terms.

Rescission and rectification are different remedies with different objectives and, depending on the nature of the case, one may justify a relief where the other cannot. Rectification requires a valid antecedent decision that was incorrectly transcribed on paper and it ensures that the written instrument accurately reflects the parties’ agreement. Rescission requires a transaction that was entered into based on a mistaken assumption about the facts or the law. It enables a court to retroactively cancel the transaction, thereby restoring the parties to their original position.

Rescission on the ground of mistake is available in a tax context, but should be granted only in rare circumstances. The test developed in Pitt v. Holt , the leading case on equitable rescission of unilateral transactions for mistake, is compatible with Canadian law and should be endorsed. A court may rescind a voluntary disposition when there is a clear causative mistake of sufficient gravity that demands the intervention of equity. Only a mistake can warrant rescission, as opposed to mere ignorance or misprediction. The test for rescission is fact-specific and objectively assessed.

Still, some types of mistake should not attract relief, for example when the taxpayer accepted the risk that a scheme might be ineffective, or when it would be against public policy to grant relief. Equity will not intervene to relieve a taxpayer from the consequences of a risk that was knowingly or recklessly accepted. Additionally, the fact that a transaction would have constituted abusive tax avoidance but for the mistake might preclude rescission because when a tax plan is aggressive, the taxpayer accepts the risk that it may not operate as intended.

However, the purported morality of a plan remains irrelevant and what constitutes an aggressive tax plan akin to abusive tax avoidance should be strictly interpreted. Taxpayers should not engage in bold tax planning on the assumption that it will be possible to rescind their transactions should that planning fail. Rescission is a discretionary remedy. Appellate intervention is only warranted if a decision to grant rescission is manifestly unjust. There is no basis to intervene in the instant case.

The taxpayers’ erroneous belief about s. 75(2) was a mistake of law, not a misprediction in relation to a change in the law. Rescission relieves against mistakes concerning the situation that existed at the time of the transaction. Injustice stemmed from the CRA’s change of position on the

interpretation of s. 75(2) after the Tax Court rendered its decision, but while it was still arguing in the Federal Court of Appeal that the Tax Court had erred in law. CRA’s discretionary decision to reassess the trusts in these circumstances takes this case into the zone of unfairness that allows equity to intervene, and neither policy reasons nor assumption of risk bars rescission in this case. The taxpayers’ plan did not constitute abusive tax avoidance. The primary goal of the plan was not to avoid payment of any tax.

The purpose of the plan was to shield assets from creditors and to do so in a manner that did not attract tax liability, with both aspects having equal importance . The plan was also not aggressive at the time it was undertaken, because CRA was unlikely to have contested the taxpayers’ position prior to the Tax Court’s decision . Deference is also owed to the chambers judge’s conclusion that the trusts never assumed the risk that CRA would reverse its

interpretation of the attribution rules. The only risk they assumed was that the general anti- avoidance rule might apply. Because rescission is a remedy of last resort, it can only be granted if no alternative remedies are available. It is not sufficient for an alternative remedy to merely exist, the alternative remedy must be practical and adequate . No alternative remedies preclude rescission in this case. Applying to the Minister for a remission of tax is an extraordinary remedy granted in rare circumstances and it is highly unlikely that the Minister would recommend it in the instant case.

A claim by the trusts against their tax advisers would also not be an adequate remedy because the tax advice was correct at the time it was given and so it is unlikely that a negligence claim would have any chance of success.

Michael Taylor and Dayna Anderson, for the appellant. Joel A. Nitikman, Q.C., and Jessica Fabbro, for the respondents. The judgment of Wagner C.J. and Moldaver, Karakatsanis, Brown, Rowe, Martin, Kasirer and Jamal JJ. was delivered by Brown J. — I. Introduction and Background [1] This Court has barred access to rectification where sought to achieve retroactive tax planning (Canada (AttorneyGeneral) v. Fairmont Hotels Inc., 2016 SCC 56, [2016] 2 S.C.R. 720, at para. 3).

Taxpayers should be taxed based on what they actuallyagreed to do and did, and not on what they could have done or later wished they had done (Fairmont Hotels, at paras. 23-24, citing ShellCanada Ltd. v. Canada, (SCC), [1999] 3 S.C.R. 622, at para. 45). At issue in this appeal is whether taxpayers are alsobarred from obtaining other equitable relief ⸺ here, rescission of a series of transactions ⸺ sought to avoid unanticipated adverse taxconsequences arising from the ordinary operation thereon of the Income Tax Act, R.S.C. 1985, c. 1 (5th Supp.).

As I explain below, theyare. [2] In 2008, Todd Collins, principal of Rite-Way Metals Ltd., and Floyd Cochran, principal of Harvard Industries Ltd.,each retained the same tax advisor to propose a plan to protect corporate assets from creditors without incurring income tax liability. Theresulting plans took advantage of the attribution rules in s. 75(2) and the inter-corporate dividend deduction in s. 112(1) of the Act.

Ineach case, a holding company was incorporated to purchase shares in an operating company, a family trust was created with the holdingcompany as a beneficiary, and funds were loaned to the trust to purchase shares in the operating company. The operating companies paiddividends to the trusts, which were attributed to the holding companies under s. 75(2). They, in turn, claimed a deduction in respect ofthose dividends under s. 112(1).

The effect was to move $510,000 from Rite-Way to the Collins family trust, and $2,085,000 fromHarvard to the Cochran family trust, without income tax being paid. [3] The proposals were based in part on the

interpretation of the provisions published by the Canada Revenue Agency(“CRA”) at the time. [4] In 2011, however, in Sommerer v. The Queen, 2011 TCC 212, 2011 D.T.C. 1162, aff’d 2012 FCA 207, [2014] 1F.C.R. 379, the Tax Court of Canada held that the attribution rules in s. 75(2) are inapplicable where the property in question was sold toa trust, as opposed to gifted or settled. Subsequently, the CRA reassessed the respondents’ returns, leading in turn to the issuance ofnotices of reassessment imposing tax liability upon the respondents in respect of the dividends.

The respondents objected, wereunsuccessful, then sued for rescission of the transactions leading to and including the payment of dividends. [5] The chambers judge granted rescission, relying on Re Pallen Trust, 2015 BCCA 222, 385 D.L.R. (4th) 499, whereinthe Court of Appeal for British Columbia, applying the English test for equitable rescission stated in Pitt v. Holt, [2013] UKSC 26,[2013] 2 A.C. 108, upheld an order rescinding the same types of transactions on the basis of a mistake about their tax consequences(2019 BCSC 1030, [2020] 1 C.T.C. 26).

While expressing concern that Re Pallen Trust had been significantly undermined by thedecisions of this Court in Fairmont Hotels and its companion case, Jean Coutu Group (PJC) Inc. v. Canada (Attorney General), 2016SCC 55, [2016] 2 S.C.R. 670, the chambers judge considered himself bound by it.

The Court of Appeal affirmed, holding that thechambers judge did not err in applying Re Pallen Trust or in exercising his equitable discretion (2020 BCCA 196, [2021] 1 C.T.C. 153).Fairmont Hotels and Jean Coutu, it said, applied narrowly to preclude rectification; neither stands for the broad preclusion of anyequitable remedy in these circumstances, or undermines the authority of Pitt v. Holt. [6] The Attorney General of Canada raises two principal grounds of appeal: first, that the courts below erred inadopting the test for equitable rescission stated in Pitt v. Holt; and secondly (and alternatively), if Pitt v.

Holt governs, then they erred inapplying it. [7] It suffices to dispose of this matter by allowing the appeal on the first ground. For the reasons that follow, a limitingprinciple of equity and, relatedly, principles of tax law stated in Fairmont Hotels and Jean Coutu are irreconcilable with the conclusion inPitt v. Holt. Equity has no place here, there being nothing unconscionable or otherwise unfair about the operation of a tax statute ontransactions freely undertaken.

It follows that the prohibition against retroactive tax planning, as stated in Fairmont Hotels and JeanCoutu, should be understood broadly, precluding any equitable remedy by which it might be achieved, including rescission. II. Analysis A. Rescission [8] Respectfully, the Court of Appeal erred by importing reasoning from Pitt v. Holt.

Its determination that equity canrelieve a tax mistake is incompatible with domestic law, being barred by a limiting principle of equity and by principles of tax law. [9] I turn first to a limiting principle of equity ⸺ indeed, the most fundamental premise of that domain, found in its

origins. Equity developed to alleviate results under “an unyielding common law” that called for the relief as a matter of “conscience” and“greater fairness” (J. Berryman, The Law of Equitable Remedies (2nd ed. 2013), at p. 2). Equitable principles “have above all adistinctive ethical quality, reflecting as they do the prevention of unconscionable conduct” (I. C. F.

Spry, The Principles of EquitableRemedies: Specific Performance, Injunctions, Rectification and Equitable Damages (9th ed. 2014), at p. 1). [10] This broad scope for courts of equity to give relief also defines its own limits (hence a “limiting” principle):transactions that do not call for relief as a matter of conscience or fairness are properly outside equity’s domain. This is reflected in someof equity’s maxims, including that a person who comes to equity must come with “clean hands” and “he who seeks equity must doequity” (Spry, at pp. 5-6; Berryman, at pp. 16 and 18; Snell’s Equity (34th ed. 2020), by J.

McGhee and S. Elliott, at paras. 5-009 to5-010). [11] The jurisdiction of equity to protect against fraud, undue influence, and unconscionable transactions is well settled(McGhee and Elliott, at para. 8-001; see also G. H. L. Fridman, The Law of Contract in Canada (6th ed. 2011), at p. 762; M. McInnes,The Canadian Law of Unjust Enrichment and Restitution (2014), at p. 1402). Generally speaking, a court of equity may grant reliefwhere it would be unconscionable or unfair to allow the common law to operate in favour of the party seeking enforcement of thetransaction.

But there is nothing unconscionable or unfair in the ordinary operation of tax statutes to transactions freely agreed upon. Asthe Court of Appeal for Ontario recognized in Canada Life Insurance Co. of Canada v. Canada (Attorney General), 2018 ONCA 562,141 O.R. (3d) 321, at para. 93, “[t]here is nothing inequitable about [Canada Life] being taxed on ‘what it did’ rather than on what itintended to achieve.” If there is to be a remedy, it lies with Parliament, not a court of equity. On this ground alone, Pitt v.

Holt and RePallen Trust cannot, in my respectful view, be taken as stating the law of British Columbia. [12] Turning to principles of tax law, the Canadian tax system is based on the Duke of Westminster principle that“taxpayers are entitled to arrange their affairs to minimize the amount of tax payable” (Canada Trustco Mortgage Co. v. Canada, 2005SCC 54, [2005] 2 S.C.R. 601, at para. 11, citing Commissioners of Inland Revenue v. Duke of Westminster, [1936] A.C. 1 (H.L.), quotedin Canada v. Alta Energy Luxembourg S.A.R.L., 2021 SCC 49, at para. 29; see also Shell Canada, at para. 46).

In Shell Canada,McLachlin J. (as she then was) explained that a court’s role is “to apply an unambiguous provision of the Act to a taxpayer’s transaction”and not to “recharacterize a taxpayer’s bona fide legal relationships” (paras. 39-40). Courts “do not have the constitutional legitimacyand resources to be tax policy makers” (Alta Energy Luxembourg, at para. 96, citing Canada Trustco, at para. 41).

Unless, therefore, astatute says otherwise, taxpayers are to be taxed, in accordance with the applicable tax statute’s ordinary operation, based on what theyactually agreed to do, and not on what they could have done (Shell Canada, at para. 45, citing Duha Printers (Western) Ltd. v. Canada, (SCC), [1998] 1 S.C.R. 795, at para. 88; Neuman v.

M.N.R., (SCC), [1998] 1 S.C.R. 770, at para. 63). [13] This principle operated in Shell Canada to the taxpayer’s favour, by allowing it to deduct from its taxable incomeinterest at the rate that it had actually paid for borrowing New Zealand dollars under debenture agreements, rather than at the lower rateit would have paid had it instead borrowed US dollars. Absent a “sham” arrangement, “the taxpayer’s legal relationships must berespected in tax cases” (Shell Canada, at para. 39). But the principle operates the other way, too.

And so, this Court applied the principlefrom Shell Canada in Fairmont Hotels and Jean Coutu in concluding that the instruments at issue in those cases could not be rectified (inFairmont Hotels) or interpreted or retroactively amended (in Jean Coutu) in order to avoid an unanticipated, adverse tax consequence.Again, legal relationships were to be respected even if they appear ill-considered in hindsight.

If, after all, taxpayers may structure theiraffairs so as to reduce their tax liability, they may also be taken as having structured their affairs in such a way that increased their taxliability. [14] This Court made precisely that point in Fairmont Hotels. “Tax consequences”, it held, “flow from freely chosen legalarrangements, not from the intended or unintended effects of those arrangements, whether upon the taxpayer or upon the public treasury”(para. 24).

The inquiry, the Court added, is into what the taxpayer agreed to do, and not into whether the taxpayer or the CRA hasobtained a “windfall”. [15] The point was made with even greater force in Jean Coutu.

While that appeal was decided under art. 1425 of the CivilCode of Québec, the reasons for decision were broadly expressed, stating generally applicable tax law principles that militate againstretroactive amendment of agreements when unforeseen tax consequences result: First, accepting PJC Canada’s position would require this Court to ignore the legal relationships that it and PJC USA originallyagreed to create, and actually created, in favour of the tax consequences they sought to achieve.

It would thus undermine one of thefundamental principles of our tax system: that tax consequences flow from the legal relationships or transactions established bytaxpayers. . . .

For instance, in Shell Canada, this Court unanimously stated the following, at para. 45: Unless the Act provides otherwise, a taxpayer is entitled to be taxed based on what it actually did, not based on what it could have done,and certainly not based on what a less sophisticated taxpayer might have done. [Emphasis in Wagner J.’s reasons.] Equally, if taxpayers agree to and execute an agreement that produce unintended tax consequences, they must still be taxed on the basisof that agreement and not on the basis of what they “could have done” to achieve their intended tax consequences, had they been betterinformed.

Tax consequences do not flow from contracting parties’ motivations or tax objectives. Second, I believe that allowing the amendment of the written documents in the instant appeal would amount to retroactive taxplanning. [Emphasis added; paras. 41-42.]

[16] From Fairmont Hotels and Jean Coutu, taken together, I draw the following interrelated principles relevant todeciding this appeal: (

a) Tax consequences do not flow from contracting parties’ motivations or objectives. Rather, they flow from the freely chosen legalrelationships, as established by their transactions (Jean Coutu, at para. 41; Fairmont Hotels, at para. 24). (

b) While a taxpayer should not be denied a sought-after fiscal objective which they should achieve on the ordinary operation of a taxstatute, this proposition also cuts the other way: taxpayers should not be judicially accorded a benefit denied by that same ordinarystatutory operation, based solely on what they would have done had they known better (Fairmont Hotels, at para. 23, citing ShellCanada, at para. 45; Jean Coutu, at para. 41). (

c) The proper inquiry is no more into the “windfall” for the public treasury when a taxpayer loses a benefit than it is into the“windfall” for a taxpayer when it secures a benefit. The inquiry, rather, is into what the taxpayer agreed to do (Fairmont Hotels, atpara. 24). (

d) A court may not modify an instrument merely because a party discovered that its operation generates an adverse and unplannedtax liability (Fairmont Hotels, at para. 3; Jean Coutu, at para. 41). [17] At issue here is whether these principles are of general application, or whether they are confined to denying pleas ofrectification.

While the Court of Appeal confined them to cases where rectification was sought, appellate judgments in Ontario andAlberta have viewed them as more broadly applicable. [18] In Canada Life, the respondent Canada Life and its affiliates undertook a series of transactions to realize a tax loss, soas to offset unrealized foreign exchange gains accrued in the same year. The CRA disallowed the claimed loss, and Canada Life soughtrectification (or, in the alternative, an exercise of “inherent jurisdiction to relieve parties retroactively from the effects of their mistakes”)to undo the transactions (para. 16).

The application judge granted rectification. On appeal, the parties agreed that the order could notstand following the decision in Fairmont Hotels, which was released after the application judge’s ruling. Canada Life cross-appealed toseek rescission, relying on Pitt v.

Holt and Re Pallen Trust as “authority that the remedy of equitable rescission of voluntary dispositionsis available, even when the objective is to avoid unintended adverse tax consequences” (para. 36). [19] “What [Canada Life] is seeking”, said the Court of Appeal in allowing the appeal and dismissing the cross-appeal, “isthe same type of intervention, by a different name, that the Supreme Court considered in Fairmont Hotels and Jean Coutu” (para. 43),and rejected (para. 7).

Fairmont Hotels, it said, “was concerned not only with the availability of rectification”, but with “impermissibleretroactive tax planning” (para. 67) in the form of a “‘rewriting of history’ . . . to correct an error leading to an unforeseen tax liability”(para. 75).

Nothing, therefore, turns on whether the relief sought involved the alteration of the agreements themselves, or to undo a“‘mistake’ . . . in the structure of the transaction” (Canada Life, at paras. 74-75). [20] Canada Life relied upon two appellate judgments in support, the first being that of the Court of Appeal of Alberta inHarvest Operations Corp. v. Attorney General of Canada, 2017 ABCA 393, 61 Alta. L.R. (6th) 1 (paras. 80-82).

There, the Court ofAppeal, citing Fairmont Hotels, first affirmed the application judge’s decision to deny rectification of documents recording shareacquisition and reorganization transactions that had led to an unanticipated tax liability. The appellant had also pleaded in the alternativethat “superior courts have equitable jurisdiction to relieve persons from the effect of their mistakes” (para. 73). This the Court of Appealrejected as also having been caught by the precedent of Fairmont Hotels (paras. 74-75). [21] Canada Life also relied on 771225 Ontario Inc. v.

Bramco Holdings Co. (1995), (ON CA), 21 O.R.(3d) 739, where the Ontario Court of Appeal had declined to relieve a taxpayer of a mistake that left her company liable for a landtransfer tax, saying: “. . . courts do not look with favour upon attempts to rewrite history in order to obtain more favourable tax treatment”(p. 742).

This conclusion flowed from the principle that tax liability is based on what was actually agreed upon and done, not on what, inretrospect, a taxpayer should have done or wished it had done. [22] I agree with the conclusion in Canada Life that Fairmont Hotels and Jean Coutu bar a taxpayer from resorting toequity in order to undo or alter or in any way modify a concluded transaction or its documentation to avoid a tax liability arising from theordinary operation of a tax statute.

The statements of principle in those judgments ⸺ that tax consequences flow from legalrelationships, that taxpayers’ liabilities should be governed by the ordinary operation of tax statutes and on what the taxpayer agreed todo, and that legal instruments cannot be modified merely because they generated an adverse tax liability ⸺ are categorical, and notrestricted to cases where rectification is sought.

To be clear: they are of general application, precluding equitable relief altogether whensought to avoid an unintended tax liability that has arisen by the ordinary application of tax statutes to freely agreed upon transactions.There is no room for distinguishing Fairmont Hotels or Jean Coutu based upon the particular remedy sought.

While a court may exerciseits equitable jurisdiction to grant relief against mistakes in appropriate cases, it simply cannot do so to achieve the objective of avoidingan unintended tax liability. [23] The foregoing ⸺ and, in particular, the statement that legal instruments cannot be undone or otherwise modified toavoid a tax liability arising from the ordinary operation of a tax statute ⸺ answers my colleague Côté J.’s objection at paras. 35-39 ofher reasons. She says that Fairmont Hotels’ endorsement of the result in Re Slocock’s Will Trusts, [1979] 1 All E.R. 358 (Ch.

D.),“generally [confirms] the availability of equitable remedies in a tax context” (para. 39). As this Court explained in Fairmont Hotels,however, rectification in Re Slocock’s Will Trusts was granted not to avoid a tax liability, but because “the deed as recorded . . . fail[ed]to record fully the terms of the parties’ original agreement” (para. 21). As a result, the plaintiff in Re Slocock’s Will Trusts was taxed onthe basis of what she had freely agreed to do ⸺ the selfsame basis on which I say the respondents ought also to be taxed. B. Pitt v.

Holt [24] From the foregoing, it follows that the Court of Appeal erred in relying upon the conclusion in Pitt v. Holt that equitycan relieve a tax mistake. That contradicts the principles outlined above, by maintaining that tax consequences are relevant to decidingwhether a party to a voluntary disposition can satisfy the test for rescission ⸺ which in turn requires “a causative mistake of sufficient

gravity . . . either as to the legal character or nature of a transaction, or as to some matter of fact or law which is basic to the transaction”(para. 122; see also para. 132). This divergence is unsurprising, given that English law lacks the prohibition against retroactive taxplanning stated in Fairmont Hotels and Jean Coutu, and operates under a different legislative framework. [25] Nor does Pitt v. Holt’s conclusion on this point account for our law that, in this case, required the Minister of NationalRevenue to apply the Act to the transactions.

By s. 220(1) of the Act, Parliament has imposed upon the Minister a duty (“[t]he Ministershall”) to “administer and enforce” the Act. No discretion is afforded the Minister or the Minister’s agents: “They are required to follow[the Act] absolutely, just as taxpayers are also required to obey it as it stands” (Harris v. Canada (C.A.), (FCA),[2000] 4 F.C. 37 (C.A.), at para. 36, citing Ludmer v. Canada, (FCA), [1995] 2 F.C. 3 (C.A.); see also Longley v.Minister of National Revenue (1992), (BC CA), 66 B.C.L.R. (2d) 238 (C.A.), at para. 19).

Quite apart fromundermining Parliament’s direction, inconsistent exercises of discretion by the Minister or the Minister’s agents create inequity amongtaxpayers (S. Templeton, “A Defence of the Principled Approach to Tax Settlements” (2015), 38 Dal. L.J. 29, at p. 32).

In aself-assessing tax system such as that provided for in the Act, taxpayers should have confidence that the Minister is administering andenforcing the same tax laws in the same way for everyone (pp. 33-34 and 68). [26] Practically, this constrains the Minister to assess a taxpayer in accordance with the facts of the matter ⸺ here, thetransactions ⸺ and the law (CIBC World Markets Inc. v. Minister of National Revenue, 2012 FCA 3, 426 N.R. 182, at paras. 16 and20-21, per Stratas J.A.; Galway v.

Minister of National Revenue, (FCA), [1974] 1 F.C. 600 (C.A.), at p. 602; Canadav. 984274 Alberta Inc., 2020 FCA 125, [2020] 4 F.C.R. 384, at para. 52). This goes to the respondents’ submission and my colleague’sconclusion that what brought this case into a “zone of unfairness” was the CRA changing its

interpretation of the provisions andreassessing the respondents retroactively in light of the Tax Court’s decision in Sommerer (transcript, at p. 59; see also Re Pallen Trust,paras. 9 and 56; C.A. reasons, at para. 30; Côté J.’s reasons, at para. 80). My colleague impugns this as a “discretionary” measure on theCRA’s part, and finds “unfairness” in its decision to reassess the respondents in light of the Tax Court’s decision while simultaneouslyarguing at the Federal Court of Appeal that it was incorrectly decided. But, and respectfully said, this ignores that the Minister wasbound to apply Parliament’s direction in the Act, as interpreted by a court of law, unless and until that

interpretation is judged to beincorrect by a higher court. Unless a statute gives the Minister the power to deviate from that direction, the Minister may not deviate; normay a court undermine that direction by resort to equity, since there is nothing unconscionable or unfair about the Minister administeringthe Act as Parliament directs. Equity is the conscience of the common law, not of Parliament. [27] In short, the “unfairness” the respondents complain of was the direct result of the ordinary operation of the Actrespecting transactions freely undertaken.

And, as already discussed, no unfairness lies in holding the respondents to the consequent taxliabilities. III. Conclusion [28] I would allow the appeal, with costs to the Attorney General in this Court and in the courts below. The judgments ofthe Court of Appeal and of the chambers judge should be set aside and the respondents’ petitions should be dismissed. The following are the reasons delivered by Côté J. — I. Overview [29] I have had the benefit of reading the reasons of my colleague Justice Brown. I agree with him that both Canada(Attorney General) v.

Fairmont Hotels Inc., 2016 SCC 56, [2016] 2 S.C.R. 720, and Jean Coutu Group (PJC) Inc. v. Canada (AttorneyGeneral), 2016 SCC 55, [2016] 2 S.C.R. 670, affirm certain governing principles of tax law, such as the principle that taxpayers shouldbe taxed based on what they did, not what they wish they had done, and the principle that retroactive tax planning is impermissible. [30] However, I am unable to agree with my colleague that Fairmont and Jean Coutu are dispositive of the case at bar.Those cases are not determinative of the availability of rescission in the tax context.

As I will explain below, rescission is, in strictlylimited circumstances, an available remedy in Canadian law that can be used to unwind transactions that were undertaken on the basis ofa mistaken assumption, even if permitting it would effectively relieve the taxpayer from payment of unexpected taxes. II. Analysis [31] I will begin by discussing the governing principles that arise from Fairmont and Jean Coutu and will explain why, inmy opinion, they do not preclude rescission in the tax context. These principles and the availability of the remedy of rescission cancoexist.

I will then consider the test for rescission and explain how the test developed in Pitt v. Holt, [2013] UKSC 26, [2013] 2 A.C.108, ought to be applied in Canadian law. Finally, before applying the legal framework to the facts of this case, I will briefly comment onthree topics that require clarification. A. In Canadian Tax Law, Fairmont and Jean Coutu Do Not Preclude Rescission for the Purpose of Unwinding Transactions ThatHave Been Entered Into Freely and Voluntarily [32] In 2016, this Court rendered decisions in two companion tax law cases, Fairmont and Jean Coutu.

My colleaguewriting for the majority in the case at bar agrees with the appellant that those cases preclude the availability of equitable remedies in thetax context and are as a result dispositive of this appeal. In my respectful view, neither Fairmont nor Jean Coutu precludes as a matter ofprinciple the availability of an equitable remedy, be it rescission or rectification, in the tax context. Rather, those cases lay downprinciples of general application that are compatible with the availability of the remedy of rescission in the tax context.

[33] In Fairmont, this Court overruled the Ontario Court of Appeal’s decision in Canada (Attorney General) v. Juliar(2000), (ON CA), 50 O.R. (3d) 728, on the basis that it had erroneously “allowed for impermissible retroactive taxplanning” (para. 24).

In Juliar, the Court of Appeal had allowed parties to rectify an agreement freely entered into because it hadproduced unintended tax consequences (Fairmont, at para. 19); that result represented a departure from this Court’s jurisprudence andfrom the fundamental principles governing rectification. [34] As was explained in Fairmont and Jean Coutu, a court cannot rectify an instrument merely because, in hindsight, theinstrument is seen to have generated an adverse and unplanned tax liability. Rather, rectification is available only where: (

i) there was aprior agreement whose terms are definite and ascertainable; (ii) the agreement was in effect at the time the instrument was executed; (iii)the instrument fails to accurately record the agreement; and (iv) the instrument, if rectified, would properly give effect to the parties’prior agreement (Fairmont, at para. 38). [35] The majority in Fairmont did not say, however, that equitable remedies — and rectification more specifically — cannever be granted in a tax context.

Instead, they simply clarified the test for rectification, emphasizing that it “is to be applied in a taxcontext just as it is in a non-tax context” (Fairmont, at para. 25). The decision did not preclude the application of equitable remedies in atax context. As A. Swan, J. Adamski and A. Y.

Na observe, “[t]he result of Fairmont Hotels is that the remedy of rectification has beenreturned or limited to its usual and proper scope” (Canadian Contract Law (4th ed. 2018), at §8.404). [36] As for Jean Coutu, it too concerned the issue of rectification of documents that had resulted in unintended taxconsequences, but under the Civil Code of Québec. In that case, Jean Coutu Group (PJC) Inc., relying on art. 1425 C.C.Q., sought tomodify documents recording a series of corporate transactions, the purpose of which was one of tax neutrality.

However, the scheme, asimplemented, did not permit Jean Coutu to avoid tax liability. The majority refused to grant the rectification sought, explaining that toallow a general intention of tax neutrality to serve as a basis for retroactively modifying contracts would effectively amount to “a kind ofcatch-all insurance for . . . inadvertence or mistakes . . . in planning transactions” (para. 42). [37] With great respect, I am of the view that my colleague unduly expands the scope of those cases.

Both of them standfor the well-settled principle that taxpayers must be taxed based on what they agreed to do, not what they ought to have done. I agreewith the Court of Appeal that the principles flowing from these decisions are not new, but are consistent with the direction in Shell Canada, as well as earlier authorities such as Re Slocock’s Will Trusts, [1979] 1 All E.R. 358(Eng. Ch. D.) . . . .

These earlier authorities confirmed that the focus of the inquiry in a claim for rectification, applicable in both the taxand non-tax context, is whether the antecedent agreement or mechanism, in definite and ascertainable terms, was properly recorded. (2020 BCCA 196, [2021] 1 C.T.C. 153, at para. 50) [38] Lest there be any doubt, the majority in Fairmont actually affirmed that equitable remedies — evenrectification — can be available in a tax context if the requisite equitable test is satisfied.

They cited with approval, and relied upon, ReSlocock’s Will Trusts, commenting that the availability of rectification in that case had “simply confirmed that, provided that theunderlying mechanism by which the parties had agreed to seek a particular tax outcome was omitted or incorrectly recorded, andprovided that all other conditions for granting rectification are satisfied, a court retains discretion to grant rectification” (para. 21). Thus,a court may order rectification where the conditions for granting this remedy are met, even where rectification results in savings for thetaxpayer.

And that is in fact what had occurred in Re Slocock’s Will Trusts, which the majority in Fairmont approvingly described as “anunremarkable application of rectification to cure an omission in the instrument recording an antecedent agreement” (Fairmont, atpara. 21). [39] Thus, neither Fairmont nor Jean Coutu generally precludes the availability of equitable remedies in a tax context.Both of those decisions clarified the test for rectification.

In Fairmont, the majority emphasized that “rectification is limited solely tocases where a written instrument has incorrectly recorded the parties’ antecedent agreement” (para. 13) and that, on the facts of that case,the party seeking rectification “could not show having reached a prior agreement with definite and ascertainable terms” (para. 39).Similarly, in Jean Coutu, which was rendered in the civil law context, the majority held that, under art. 1425 C.C.Q., a general intentionof tax neutrality that is not related to obligations whose objects are determinate or determinable cannot on its own give rise to a commonintention that would form part of the original contract and permit the requested modifications. [40] Moreover, while both Fairmont and Jean Coutu clarified the circumstances in which the remedy of rectification isavailable, neither addressed specifically the availability of rescission.

This is the consensus in the academic literature as well. Forexample, T. Fitzsimmons and E. S. Roth explain that [t]he majority of the Supreme Court of Canada in Fairmont made no reference to rescission and did not determine (or even comment on)the circumstances in which the remedy of rescission can or should be granted.

Although rectification and rescission share a doctrinaloverlap and common evidentiary foundation, they are separate and distinct equitable remedies, and on the basis of the court’s reasons forjudgment, it appears that the availability of the equitable remedy of rescission should therefore have been unaffected by the decision inFairmont. (“Rectification, Rescission, and Other Equitable Remedies After Fairmont Hotels Inc.”, in Canadian Tax Foundation, Report ofProceedings of the Sixty-Ninth Tax Conference (2018), 30:1, at p. 30:34; see also T. J. Agioritis, “Is Rectification Still a Remedy?

APractical Overview”, in Canadian Tax Foundation, 2017 Prairie Provinces Tax Conference & Live Webcast (2017); R. Pandher andB. Graversen, “Does Fairmont Hotels Eliminate All Equitable Remedies in the Tax Context?” (2018), 66 Can. Tax J. 931, at p. 940.) [41] Rescission and rectification ought not to be confused. As Pandher and Graversen write, “[t]he same brush cannot beused to paint all equitable remedies in the tax context” (p. 940). Rescission and rectification are two different remedies with different

objectives. They “are not simply two roads leading to the same place” (R.F., at para. 40). Hence, depending on the nature of the case,one may justify a relief where the other cannot. [42] Rectification requires a valid antecedent decision to carry out a particular transaction that was incorrectly transcribedon paper. The premise underlying this remedy is that it would be unfair to hold a person to be bound by a transaction they never agreedto (Swan, Adamski and Na, at §8.406). As for rescission, it relieves against a mistake.

It presupposes that the transaction was transcribedcorrectly but was entered into under a mistaken assumption about the facts or the law. If granted, rescission “puts the parties in statusquo ante and restores things, as between them, to the position in which they stood before the contract was entered into” (Guarantee Co.of North America v. Gordon Capital Corp., (SCC), [1999] 3 S.C.R. 423, at para. 39 (emphasis added), quoting AbramSteamship Co. v. Westville Shipping Co., [1923] A.C. 773 (H.L.), at p. 781; see also Snell’s Equity (34th ed. 2020), by J. McGhee andS. Elliott, at para. 15-001).

In other words, the purpose of rectification is to ensure that a written instrument accurately reflects theparties’ antecedent agreement, whereas rescission enables a court to retroactively cancel a transaction that was entered into by mistake,thereby restoring the parties to their original position. [43] In sum, Fairmont and Jean Coutu stand for the following propositions: (

a) If a taxpayer does not meet the test for an equitable remedy, then a court has no discretion to grant that remedy, even if thetaxpayer may have to pay taxes unexpectedly through no fault of its own (Fairmont, at paras. 13 and 39; Jean Coutu, at para. 23). (

b) If the taxpayer meets the test for an equitable remedy, then the court may grant it, even if doing so would effectively relieve thetaxpayer from payment of the unexpected taxes (Fairmont, at paras. 21-22; Jean Coutu, at para. 24). (

c) A common intention to limit or avoid tax liability is insufficiently precise to evince an existing prior agreement with definite andascertainable terms (Fairmont, at paras. 39-40; Jean Coutu, at paras. 23 and 50). Contrary to my colleague’s conclusion, Fairmont and Jean Coutu cannot be read as precluding all equitable remedies from potentiallyapplying in a tax law context. B. Rescission for Mistake in the Case of a Voluntary Disposition of Property [44] The leading case on equitable rescission of unilateral transactions for mistake is Pitt v. Holt, a 2013 decision of theSupreme Court of the United Kingdom.

My colleague asserts that the test for equitable rescission stated in Pitt v. Holt cannot be adoptedin Canada, because its effect is that tax consequences are relevant to deciding whether a party to a voluntary disposition of property cansatisfy the test for rescission (para. 24).

I respectfully disagree. [45] According to the propositions outlined above, if a taxpayer does not meet the test for an equitable remedy, then acourt has no discretion to grant that remedy, even if the taxpayer may have to pay taxes unexpectedly, through no fault of its own.However, if the taxpayer meets the test for an equitable remedy, then the court may grant it, even if doing so would effectively relievethe taxpayer from payment of the unexpected taxes (R.F., at para. 8). Therefore, the test developed by Lord Walker in Pitt v. Holt iscompatible with Canadian law and should be endorsed by this Court.

(1) Test for Rescission for Mistake in the Case of a Voluntary Disposition of Property [46] A court may rescind a voluntary disposition when there is “a clear causative mistake of sufficient gravity thatdemand[s] the intervention of equity” (A. H. Oosterhoff, “Causative Mistake of Sufficient Gravity, or Retroactive Tax Planning? AComment on Re Pallen Trust” (2016), 35 E.T.P.J. 135, at p. 144). And “the test will normally be satisfied only when there is a mistakeeither as to the legal character or nature of a transaction, or as to some matter of fact or law which is basic to the transaction” (Pitt v.

Holt,at para. 122). [47] The test for rescission does not involve a strict set of rules. Rather, it is a fact-specific, objectively assessed“in-the-round” approach, as was explained in Pitt v. Holt: The evaluation of what is or would be unconscionable must be objective. . . . The gravity of the mistake must be assessed by a close examination of the facts, whether or not they are tested by cross-examination,including the circumstances of the mistake and its consequences for the person who made the vitiated disposition.

Other findings of factmay also have to be made in relation to change of position or other matters relevant to the exercise of the court’s discretion. . . . . . . The injustice (or unfairness or unconscionableness) of leaving a mistaken disposition uncorrected must be evaluated objectively, but withan intense focus . . . on the facts of the particular case. . . . . . .

. . . The court cannot decide the issue of what is unconscionable by an elaborate set of rules. It must consider in the round the existenceof a distinct mistake (as compared with total ignorance or disappointed expectations), its degree of centrality to the transaction inquestion and the seriousness of its consequences, and make an evaluative judgment whether it would be unconscionable, or unjust, toleave the mistake uncorrected. The court may and must form a judgment about the justice of the case. [paras. 125-126 and 128] [48] Nevertheless, Lord Walker stated in Pitt v.

Holt, and I agree, that “there are some types of mistake about tax whichshould not attract relief” (para. 132). Rescission on the ground of mistake should not be granted when the taxpayer has accepted the riskthat the scheme might be ineffective, or when it would be against public policy to grant relief. [49] I pause here to note that only a mistake can warrant rescission, as opposed to mere ignorance or “misprediction” (Pittv. Holt, at para. 104).

As Lord Walker explained, “[a] misprediction relates to some possible future event, whereas a legally significantmistake normally relates to some past or present matter of fact or law” (para. 109). In other words, a misprediction is a belief that laterturns out to be wrong, whereas a mistake is a belief that is wrong at the time of the transaction (W. Seah, “Mispredictions, Mistakes andthe Law of Unjust Enrichment” (2007), 15 R.L.R. 93, at p. 100).

Similarly, a taxpayer’s ignorance or inadvertence cannot becharacterized as a mistake, as that would be incompatible with the self-reporting and self-assessing nature of our tax system. [50] Ultimately, equity will not intervene to relieve a taxpayer from the consequences of a risk that was knowingly orrecklessly accepted. A taxpayer who is fully aware of potential tax issues associated with a transaction, or who proceeds with a tax planin a reckless or ignorant manner, generally assumes the risk of being wrong and having to pay taxes. [51] For example, in Neville v.

National Foundation for Christian Leadership, 2013 BCSC 183, aff’d 2014 BCCA 38, 350B.C.A.C. 7, Mr. Neville made a donation to a foundation on the understanding that the foundation “could” use all or part of the money topay a scholarship to his daughter. Before he made the donation, the foundation had warned him that the Canada Revenue Agency(“CRA”) might not accept the tax receipt as evidencing a valid gift and that the plan was “risky”. That case is a clear example of anaccepted risk. Mr.

Neville was aware of and assumed the risk that the CRA would disallow the tax credit he was claiming; there was nomistake, and rescission was unavailable to him. [52] Additionally, a transaction that would have constituted abusive tax avoidance but for a mistake might be aconsideration in the “in-the-round” analysis and preclude rescission. That would be an important element in the overall analysis, as itwould highlight the risk the taxpayer has accepted and help to determine whether equity should intervene.

When a tax plan is“aggressive”, the taxpayer is accepting the risk that the plan will not operate as intended. This weighs against the availability ofrescission. [53] However, the purported morality of a plan remains irrelevant. As this Court recently reiterated in Canada v.

AltaEnergy Luxembourg S.A.R.L., 2021 SCC 49, it is important to distinguish what is immoral from what is abusive: “Taxpayers are allowedto minimize their tax liability to the full extent of the law and to engage in ‘creative’ tax avoidance planning, insofar as it is not abusivewithin the meaning of the [general anti-avoidance rule (“GAAR”)]” (para. 48).

Therefore, rather than focusing on the purported moralityof taxpayers arranging their affairs within the acceptable confines of the law, the focus should be on the risk the taxpayers accepted. [54] It can be difficult to establish what constitutes an “aggressive” tax plan akin to abusive tax avoidance. Consequently,this concept should be strictly interpreted: While a court may be reluctant to grant rescission to provide a taxpayer with relief from its own “aggressive” tax planning, thatlimitation should be narrowly interpreted.

Courts may be expected to recognize the longstanding principle that taxpayers can structuretheir affairs to mitigate their tax burden, but structuring that goes beyond the pale may be subject to GAAR. . . . There will often be somelevel of uncertainty around tax-structuring outcomes, and it would not be reasonable for a judge to conjure a notional spectrum ofinappropriate but legal behaviours against which to gauge whether to grant equitable relief, unless the transaction was attacked withGAAR as the primary assessing position. (J. Sorensen and A.

Yuk, “Equitable Rescission for Tax Mistakes: It’s Not Over (Until it’s Over)” (2020), 68 Can. Tax J. 1149, atp. 1156) [55] In sum, for rescission to be granted, the mistake needs to be sufficiently serious. Rescission will be availablewhenever failure to grant it would result in unfairness or in an injustice (P. S. Davies and S. Douglas, “Tax Mistakes Post-Pitt v Holt”(2018), 32 T.L.I. 3). [56] In accordance with this Court’s approach in Fairmont and Jean Coutu, rescission on the ground of mistake is anavailable remedy in a tax context just as it is in a non-tax context.

That being said, rescission based on a mistake that relates solely to thetax consequences of a transaction should be granted only in rare circumstances. This is so because, as LeBel J. stated in Quebec (Agencedu revenu) v.

Services Environnementaux AES inc., 2013 SCC 65, [2013] 3 S.C.R. 838, “[t]axpayers should not view this recognition . . .as an invitation to engage in bold tax planning on the assumption that it will always be possible for them to [rescind] their [transactions]retroactively should that planning fail” (para. 54; Fairmont, at para. 82; Jean Coutu, at para. 21). [57] Similarly, in Shell Canada Ltd. v. Canada, (SCC), [1999] 3 S.C.R. 622, at para. 45, this Courtstressed that a taxpayer should expect to be taxed “based on what it actually did, not based on what it could have done”.

As the majorityof the Court explained in Fairmont, just as taxpayers should not be denied a benefit because others have not availed themselves of thesame benefit, “taxpayers should not be judicially accorded a benefit based solely on what they would have done had they known better”(para. 23). While this principle does not preclude the availability of recession in a tax context, Shell likewise underscores the fact thatrescission is a remedy that may be granted only in rare circumstances where required by equity.

(2) Alternative Remedies

[ 58 ] Finally, rescission is a remedy of “last resort”: even if a party meets the test for rescission, it can be granted only if no alternative remedies are available. [ 59 ] There are two competing approaches to the assessment of the availability of alternative remedies. In Canada Life Insurance Co. of Canada v. Canada (Attorney General) , 2018 ONCA 562 , 141 O.R. (3d) 321, the Ontario Court of Appeal held that the mere existence of a legal remedy warrants denying equitable relief.

The court framed the question not as whether an alternative remedy would be successful, but solely whether there exists a remedy at law. The opposite view was expressed by the British Columbia Court of Appeal in 5551928 Manitoba Ltd. v. Canada (Attorney General) , 2019 BCCA 376 , 439 D.L.R. (4th) 483: it held that, when a court must determine whether an equitable remedy should be granted, it is not sufficient for an alternative remedy to merely exist. The court must, in exercising its discretion, ask whether the alternative remedy is practical or adequate. [ 60 ] The second approach should be endorsed.

The mere theoretical possibility of an alternative remedy where there is no evidence on how the remedy might apply in practice is insufficient to displace the court’s equitable jurisdiction to grant rescission. The alternative remedy must be sufficient to replace the relief being sought. In 5551928 Manitoba Ltd. , a case concerning rectification, Newbury J.A. rightfully quoted a comment from Snell’s Equity that “rectification will not be decreed if the desired result can conveniently be achieved by other means” (paras. 40-41 (emphasis in original), quoting Snell’s Equity (31st ed. 2005), at para. 43-04).

She went on to “doubt that Equity would force upon a party . . . an ‘alternative’ that is neither practical nor certain” (para. 41). C. Further Remarks [ 61 ] Before applying the test for rescission to the facts of this case, I wish to discuss three matters that arise in this appeal.

(1) Standard of Review [ 62 ] Rescission is an equitable remedy that can be granted on a discretionary basis. It is trite law that deference is generally owed to discretionary decisions. Absent palpable and overriding error, deference is owed to findings of fact. Absent an error of law, erroneous principles or irrelevant considerations, deference is owed to a trial judge’s exercise of discretion ( Wilson v. Alharayeri , 2017 SCC 39 , [2017] 1 S.C.R. 1037, at para. 59 ).

Thus, if the trial judge “has given sufficient weight to all relevant considerations and the exercise of discretion is not based on an erroneous principle, appellate reviewers must generally defer” ( Canada (Attorney General) v. Fontaine , 2017 SCC 47 , [2017] 2 S.C.R. 205, at para. 36 ). If there is no such error, appellate intervention is only warranted if the decision is manifestly unjust.

(2) Sommerer v. The Queen [ 63 ] In 2012, the Federal Court of Appeal affirmed the Tax Court of Canada’s decision in Sommerer v. The Queen , 2011 TCC 212 , 2011 D.T.C. 1162, in which that court had narrowly interpreted s. 75(2) of the Income Tax Act , R.S.C. 1985, c. 1 (5th Supp .) (“ ITA ”) ( Sommerer v. Canada , 2012 FCA 207 , [2014] 1 F.C.R. 379). [ 64 ] Section 75(2) of the ITA reads as follows: 75

(2) If a trust, that is resident in Canada and that was created in any manner whatever since 1934, holds property on condition (

a) that it or property substituted therefor may (

i) revert to the person from whom the property or property for which it was substituted was directly or indirectly received (in this subsection referred to as “the person”), or (ii) pass to persons to be determined by the person at a time subsequent to the creation of the trust, or (

b) that, during the existence of the person, the property shall not be disposed of except with the person’s consent or in accordance with the person’s direction, any income or loss from the property or from property substituted for the property, and any taxable capital gain or allowable capital loss from the disposition of the property or of property substituted for the property, shall, during the existence of the person while the person is resident in Canada, be deemed to be income or a loss, as the case may be, or a taxable capital gain or allowable capital loss, as the case may be, of the person. [ 65 ] Before Sommerer , there was a general understanding in the tax community, which the CRA shared, that s. 75(2) would apply to a sale of shares as well as to a gift of shares.

In the proceedings in Sommerer , the CRA, relying on its

Interpretation Bulletin IT-369R(SR), “Attribution of Trust Income to Settlor” (June 24, 1994), argued that s. 75(2) applied both to shares sold and to shares gifted: a person other than the settlor could transfer property to a trust and become subject to the attribution rules. The CRA advanced this position in its submissions to both the Tax Court and the Federal Court of Appeal. In the Tax Court, Miller J. held that the CRA’s

interpretation was wrong. He concluded that the “person” referred to in s. 75(2) had to be the settlor of the trust. Therefore, a

person other than a settlor could not transfer property to a trust and become subject to the attribution rules of s. 75(2). The CRA appealedthe Tax Court’s decision and maintained its position in the Federal Court of Appeal, arguing that the trial judge had erred in hisinterpretation of s. 75(2), because a textual, contextual, and purposive

interpretation of the provision supported the position that itapplied both to shares sold and to shares gifted. [66] However, the Federal Court of Appeal upheld Miller J.’s decision, holding that the “person” as defined in s. 75(2)(a)(

i) of the ITA must be the settlor of the trust, and that the attribution rules therefore did not apply where the property in question was soldto a trust, as opposed to gifted to, or settled on, the trust. The court disagreed with the CRA’s long-standing view that a person other thanthe settlor may transfer property to a trust and become subject to the attribution rules of s. 75(2).

(3) Re Pallen Trust [67] In 2015, the British Columbia Court of Appeal rendered its decision in Re Pallen Trust, 2015 BCCA 222, 385 D.L.R.(4th) 499. The facts in Pallen and in the case at bar are nearly identical.

Indeed, as the British Columbia Supreme Court noted in itsreasons in the instant case, “except for the names, the sections of the [reorganization] plan quoted in the chambers and Court of Appealjudgments in Pallen are identical to the . . proposals for Collins and Cochran Family Trusts” (2019 BCSC 1030, [2020] 1 C.T.C. 26, atpara. 38). [68] In Pallen, the Court of Appeal considered precedents — such as 771225 Ontario Inc. v.

Bramco Holdings Co. (1995), (ON CA), 21 O.R. (3d) 739, to which my colleague refers — that reflect a public policy view that “taxpayers shouldnot be encouraged to engage in aggressive tax planning and, when it proves to be unsuccessful, invoke the ‘mistake’ route to equitablerescission” (Pallen, at para. 52). Rescission was nonetheless granted on the basis of the specific facts of the case. [69] In light of the reasons set out above, one fact stands: Fairmont and Jean Coutu did not cause the result in Pallen to bewrong.

Not only do I agree with the Court of Appeal’s conclusion in the case at bar that Pallen remained good law in British Columbiafollowing Fairmont and Jean Coutu, but I also conclude that Pallen was rightfully decided. Rescission “will be available if all theconditions for granting [it] are met, even if a tax advantage is achieved” (C.A. reasons, at para. 55). I will discuss Pallen in more detailin the application of the law to the facts, to which I now turn. III.

Application [70] As I will explain, the chambers judge in this case did not err in granting rescission, and the Court of Appeal was rightto uphold his decision. Indeed, I am of the view that there is no basis for an appellate court to intervene with the chambers judge’sexercise of discretion. A. The Respondents Made a Mistake, Not a Misprediction [71] I explained above that rescission cures only a mistake of law, not mere ignorance or a misprediction. Thus, the firstissue to be decided is whether the respondents made a mistake rather than a misprediction. If the

interpretation of s. 75(2) in Sommererwere deemed to have changed the law, then the respondents’ belief would have amounted to a misprediction, as they would not haveanticipated that the law might be changed by a future judicial decision. I conclude that the respondents’ erroneous belief about s. 75(2) ofthe ITA was a mistake of law, not a misprediction in relation to a change in the law. [72] Given that s. 75(2) had never been analyzed by a court when the Tax Court of Canada released its decision inSommerer, that decision did not change the law. It stated what the law had always been even though the law had been erroneouslyinterpreted by the CRA and by tax professionals. Indeed, the CRA’s

interpretation bulletins are not authoritative sources of law (MattabiMines Ltd. v. Ontario (Minister of Revenue), (SCC), [1988] 2 S.C.R. 175, at pp. 195-97). The argument that Sommererchanged the law cannot therefore stand. The respondents’ belief that s. 75(2) applied was consistent with the CRA’s

interpretation at thetime of the transactions in 2008 and 2009. That belief turned out to be wrong, as is clear from the decision in Sommerer. [73] As I explained in discussing Pitt v. Holt, rescission relieves only against mistakes concerning the situation that existedat the time of the transaction. Such a mistake is what happened in the present case. Rescission is therefore available to remedy therespondents’ mistake about the law. It must now be determined whether, based on the “in-the-round” approach, rescission should havebeen granted by the chambers judge. B. The Respondents Meet the Pitt v.

Holt Test for Rescission [74] Rescission requires an inquiry that is focused on the specific facts of the case in question. Every minor fact can makea difference, and the decision is highly discretionary. The chambers judge, relying on the reasons of Newbury J.A. in Pallen, applied theproper test and weighed all of the relevant factors. [75] The chambers judge noted that, in Pallen, the facts the Court of Appeal had had before it when it upheld the order forrescission were substantially analogous to the facts of this case.

In Pallen, the Court of Appeal had held that “the existence of [a]‘common general understanding’ regarding the operation of s. 75(2)” took the case “into the zone of unfairness” (para. 56). In the presentcase, the chambers judge held that Pallen was analogous and binding, making the following findings of fact at para. 56:

a) The purposes of the plans were substantially the same;

b) The material steps in the various plans were virtually identical;

c) The plans were devised by the same accounting firm within approximately ten months of each other;

d) There was a risk of GAAR applying to all of the plans and the accounting firm MNP advised of this risk;

e) All matters concern the 2008 tax year (although the matters [here] also concern the 2009 tax year);

f) The tax environment was the same (i.e. there was a general understanding, including by CRA, that s. 75(2) of the ITA applied to a sale of shares to a trust at fair market value);

g) The effectiveness of the plans depended on the application of s. 75(2) of the ITA to deem the dividend income as being received by the holding company;

h) The Sommerer decision thwarted all of the plans;

i) All of the trusts were re-assessed after the Sommerer decision and by the same auditor; and

j) The reason for the reassessments was the Sommerer decision. [ 76 ] In both Pallen and the case at bar, the lower courts reasoned that the injustice stemmed from the CRA’s change of position on the

interpretation of s. 75(2) after Sommerer was released. I agree with their reasoning. As in Pallen , what takes this case into the zone of unfairness is the CRA’s retroactive application of s. 75(2) . At the time of the transaction, the taxpayer’s understanding was that the attribution rules of s. 75(2) applied as long as the trust held the property.

This view was shared by the CRA and by tax professionals. [ 77 ] It was only after the Tax Court had rendered its decision in Sommerer in April 2011, but before the Federal Court of Appeal had upheld the decision, that the CRA first notified the respondents that their 2008 to 2010 tax returns were under review. And it was while arguing in the Federal Court of Appeal in Sommerer that the trial judge had erred in law that the CRA first proposed to reassess the trusts at issue here and to include the dividends as income.

The CRA’s position was: first, the application of s. 75(2) did not preclude an equivalent inclusion of the dividends in the trusts’ income by operation of s. 12(1)(j); second, if the CRA’s position on s. 75(2) was wrong and the decision in Sommerer was upheld, then s. 75(2) would not apply; and third, in the alternative, the GAAR should apply (C.A. reasons, at para. 14; see also A.R., vol.

I, at pp. 176-77). [ 78 ] In December 2012, after the Federal Court of Appeal had upheld the Tax Court’s decision in Sommerer , the CRA notified the respondents that, in light of that ruling, the dividends had to be included in their income. The CRA finalized its audit in January 2016 and issued notices of reassessment in March 2016. [ 79 ] With respect, my colleague misapprehends what takes this case into the zone of unfairness. He explains that the Minister was bound to apply Parliament’s direction in the ITA as interpreted by a court of law (para. 26).

As a result, it forecloses, he says, the respondents’ submissions on unfairness. While I agree that s. 220(1) of the ITA imposes upon the Minister a duty to “administer and enforce” the ITA , I cannot agree that that s. 220(1) of the ITA is dispositive of the issue of unfairness. [ 80 ] In my view, what takes this case into the zone of unfairness is not the application of the law, but rather the CRA’s discretionary decision to reassess the taxpayers based on a retroactive approach to s. 75(2) . Unfairness results when the CRA reverses a long-standing

interpretation and then seeks to reassess a taxpayer retroactively. To be clear, I wish to emphasize that, while arguing in the Federal Court of Appeal that the trial judge in Sommerer had erred in law in his

interpretation of s. 75(2), the CRA was seeking to reassess the taxpayers in this case by applying the same legal

interpretation it was simultaneously arguing to be incorrect. This unfairness allows equity to intervene.

(1) Neither Policy Reasons Nor Assumption of Risk Bars Rescission in This Case (

a) The Respondents’ Plan Was Not an Abusive Tax Avoidance Scheme [ 81 ] The appellant submits that the chambers judge erred in exercising his discretion by failing to consider that the transactions at issue would have constituted abusive tax avoidance but for the mistake. The appellant relies on Fiducie Financière Satoma v. The Queen , 2018 FCA 74 , 2018 D.T.C. 5052, in which the Federal Court of Appeal deemed a similar scheme to constitute abusive tax avoidance.

In Satoma , the Federal Court of Appeal concluded that a scheme involving the combined use of ss. 75(2) and 112(1) of the ITA (as in the case at bar) constituted abusive tax avoidance under the GAAR. Under the scheme in question, money was gifted to a trust and used by the trust to purchase shares, and the related dividends were attributed to the donor corporation pursuant to s. 75(2) .

The donor corporation used the attributed funds to donate surplus capital to the dividend paying corporation, reported the dividend income, and claimed an intercorporate dividend deduction in the same amount under s. 112(1) , so that no taxes were paid on the issued dividends. The scheme complied with the ITA because the shares were substituted property for the gifted property, but the

Minister considered the result abusive. The plan had the dual purpose of (1) transferring funds held by the corporation to the trust to finance the operations of related companies and (2) shielding the funds in question from potential lawsuits directed against those related companies. [ 82 ] My understanding is that the appellant is suggesting that the result reached in Satoma should also have been reached in this case.

In other words, the scheme in the present case should have been found to constitute abusive tax avoidance, which would be a significant factor of the “in-the-round” test. [ 83 ] Although there are some similarities between this case and Satoma , the courts below were right to distinguish that case. The chambers judge stated that there are two important distinctions between Satoma and the present case: (1) in Satoma , the taxpayer’s reassessments were based solely upon the GAAR; and (2) the purposes of the transactions are different.

I find no error in this regard in the chambers judge’s reasons. [ 84 ] In Satoma ,
