The federal government has identified five priority transmission intertie projects it will support as part of implementing Powering Canada Strong, Canada's national electrification strategy released in May by Prime Minister Mark Carney's government, Energy Minister Tim Hodgson announced June 26.

The projects are intended to let provinces and territories share electricity more efficiently across borders, a capacity the federal government has tied directly to its broader goal of doubling Canada's electricity generation and transmission capacity by 2050 — an expansion driven in part by rising demand from heat pump adoption, electric vehicle charging and data centre growth.

The Five Power-Line Projects

Hodgson's announcement named intertie upgrades connecting Alberta and Saskatchewan, including replacement and upgrading of the McNeill converter station near Medicine Hat, Alberta, intended to increase electricity trade between the two provinces by 250 megawatts and lift transfer capability along the Regina-Winnipeg corridor by up to two gigawatts. New subsea transmission cables connecting Prince Edward Island and New Brunswick are also included, intended to reinforce the transmission system linking those provinces with Nova Scotia. A separate project would link Yukon's electricity grid to British Columbia's through an estimated 800-kilometre high-voltage line, which the federal government said is intended to support industrial and economic development in Yukon, including the territory's critical-minerals sector.

The federal government framed the announcement as an early, concrete step toward implementing the broader strategy, which itself remains in a four-month consultation period with provinces, territories, Indigenous groups, industry and labour before a finalized policy document is expected.

Powering Canada Strong, released May 14, commits the federal government to expanding support for energy-saving retrofits across up to one million Canadian households through a combination of grants, financing and other measures, including programs intended to help households switch from propane, oil and electric baseboard heating to heat pumps. The strategy separately commits roughly $6 billion toward recruiting, training and hiring 80,000 to 100,000 new Red Seal trades workers over five years, with funding aimed in part at improving apprenticeship completion rates — a recurring constraint cited by HVAC contractors and trade associations across Canada.

The strategy's electricity-demand projections explicitly cite rising heat pump adoption, alongside EV charging and data centre growth, as a driver of increasing winter peak demand on provincial grids — a dynamic that ties grid capacity expansion directly to the pace at which Canadian households can be expected to electrify space heating over the coming decades.

Reaction to Canada's Electrification Strategy

Clean Energy Canada, an energy policy research organization, welcomed the retrofit and electrification commitments in the broader strategy while raising concerns that the policy document gives an outsized role to natural gas generation relative to renewable sources. Evan Pivnick, the organization's associate director of public affairs, said the strategy "sends an important signal" on electrification as a nation-building priority, while arguing the government should prioritize clean generation sources over expanded natural gas capacity as it implements the plan.

Other policy critics, including the Fraser Institute, have raised separate concerns about the strategy's demand-management provisions, which could allow utilities to draw on connected home battery systems and electric vehicles during periods of peak grid stress — a mechanism the institute has characterized as expanding government control over household energy use.

What's Next

The federal government has set a four-month consultation window covering the strategy's identified action areas, with provinces, territories, Indigenous Peoples, industry and unions invited to provide input before specific funding mechanisms and timelines are finalized. The government has also said it plans to introduce Bill S-4, legislation that would modernize the Energy Efficiency Act, strengthen its enforcement framework and account for new market participants and technologies, including ministerial authority to grant exemptions intended to support economic growth and competitiveness.

For HVAC contractors and distributors operating in Canada, the strategy's retrofit and grid-capacity commitments remain in a pre-funding consultation phase, with the specific design of any heat pump rebate or financing mechanism still to be determined as part of that process.

The five intertie projects named June 26 are themselves still subject to further engineering, regulatory and federal-provincial cost-sharing negotiations before construction timelines can be set. Hodgson's office has not published a combined cost estimate for the five projects or a target completion date, saying instead that each will continue through its own provincial regulatory and permitting process before federal financing commitments are finalized.
