On the recommendation of the undersigned, the Lieutenant Governor of Ontario, by and with the advice and concurrence of the Executive Council of Ontario, orders that:

Whereas Ontario considers it critical to expand Ontario’s transmission system to provide a reliable and adequate supply of electricity to support economic growth and electrification initiatives throughout Northeastern and Eastern Ontario;

And

whereas the Independent Electricity System Operator, the organization responsible for ensuring the reliability of Ontario’s electricity grid, has published:

A bulk planning report dated October 27, 2022, entitled the “Need for Northeast Bulk System Reinforcements”, which recommended a new transmission line running between Sault Ste. Marie and Sudbury and a new transmission line in the Sudbury region as the appropriate solution required to meet expected demand growth and system needs; and

A bulk planning report dated December 8, 2022, entitled the “Gatineau Corridor End-of-Life

And

whereas the Lieutenant Governor in Council may make an order under

section 96.1 of the Ontario Energy Board Act, 1998 (the “Act”) declaring that the construction, expansion or reinforcement of an electricity transmission line specified in the order is needed as a priority project;

And
