Ontario and Toronto are collaborating to build a third electricity transmission line to meet the city's rapidly growing power demand, which is expected to double by 2050, particularly in the downtown core. This project aims to support urban growth, major transit expansions like the Ontario Line, and the electrification of vehicles, heating, and industry, while enhancing grid reliability. The Independent Electricity System Operator (IESO) will recommend the line's location by August, with construction expected to take 7-10 years.

What: Ontario and Toronto are planning to build a third electricity transmission line to power Toronto's downtown and replace aging infrastructure.
When: News conference on Wednesday morning (June 4, 2025, inferred from article publish date). Current lines expected to reach capacity in early 2030s. Project completion expected in 7-10 years. IESO recommendation by August (unspecified year).
Where: Toronto, Ontario, Canada. Specifically, downtown Toronto, Manby Transmission Station (near Kipling Road and Dundas Street), Leaside Transformer Station (near Overlea Boulevard and Millwood Road). Potential options for new line include Pickering, Lake Ontario, or existing corridors.
Why: Toronto's electricity demand is projected to double by 2050 due to population growth, new homes, major transit expansions (Ontario Line), and electrification of vehicles, heating, and industry. Existing transmission lines will reach capacity in the early 2030s.
How: The Independent Electricity System Operator (IESO) determined the need for a third line. The Ontario government will decide on construction after IESO's final recommendation. Consultations with City of Toronto, Indigenous communities, stakeholders, and the public are underway.
