Canada, Ontario, Toronto: The Ontario government has unveiled plans for a third electricity transmission line to support Toronto’s expanding energy needs. With downtown demand expected to double by 2050, the new line will help maintain a reliable power supply and support upcoming developments like the Ontario Line transit project.
At a press conference, Ontario’s Minister of Energy and Mines, Stephen Lecce, said the project aims to prepare Toronto’s energy infrastructure for future growth. “It is not just about homes or transit,” he noted, “but also about the shift to electric vehicles, new heating systems, and expanding industries.”
Toronto currently relies on two transmission supply routes – one from the west at Manby Transmission Station and one from the east at Leaside Transformer Station. These lines are projected to reach full capacity by the early 2030s.
To address this, the Independent Electricity System Operator (IESO) has proposed a third line and will finalize recommendations by August 2025. Three options are under consideration: an overland route from Pickering to Leaside, an overland route from Pickering to the Port Lands, or an underwater cable from Darlington or Pickering to the Port Lands.
Construction is expected to take between seven and ten years. Over the summer, IESO will gather feedback from the City of Toronto, Indigenous communities, stakeholders, and the public to determine the most suitable option.
