Hydro One has successfully delivered the Etobicoke Greenway Transmission Line, with the 6.5-kilometre, 230-kilovolt project delivered on time and under budget.

The line spans through an existing corridor between Etobicoke’s Richview and Manby transformer station, and will deliver up to 300 megawatts of electricity to western Toronto, southern Mississauga, and Oakville.

The project involved the replacement of an existing idle transmission line, along with upgrading the capacity of the Richview and Manby transformer stations. Hydro One procured approximately 98 per cent of the materials needed to perform this work from Canadian companies.

Construction began in late 2025, supporting 100 jobs throughout the process. The project came in $10 million under budget, with these savings put toward a recreational trail alongside the transmission corridor.

“The Etobicoke Greenway transmission line adds critical capacity for Toronto and the western GTA while demonstrating Hydro One’s continued ability to deliver complex infrastructure safely, on time and below budget. As Ontario’s trusted developer and operator of transmission lines, we play a key role in building an electricity system that supports growth, creates jobs and keeps the province competitive for decades to come,” said Hydro One president and CEO Megan Telford.
