The Ontario government has announced a historic effort to connect and strengthen Canada’s electricity systems by launching a first-of-its-kind interprovincial-territorial partnership to build transmission infrastructure needed to power the country’s next generation of growth. The landmark agreement, initiated by Ontario, will bring together British Columbia, Alberta, Saskatchewan, Manitoba, New Brunswick, Yukon, Prince Edward Island, Nova Scotia and the Northwest Territories to advance new electricity transmission projects and strategic interties across Canada.
Following Ontario’s Connecting Canada – Building an Energy Superpower Summit in September 2025, provincial and territorial energy ministers agreed that expanding electricity transmission between jurisdictions is essential to meeting rising demand, strengthening energy security and unlocking the full value of Canada’s clean and diverse energy resources. The agreement marks a major nation-building milestone, breaking down longstanding barriers between provincial grids and enabling a more connected, resilient and self-reliant energy system.
Under this agreement, provinces and territories will collaborate to: i) Identify and advance new interprovincial and territorial transmission infrastructure, including key intertie projects with elevated speed; ii) Expand electricity trade within Canada, helping regions meet growing demand and maximise the use of clean, reliable power before exporting abroad.
