Etobicoke Greenway line adds 300 MW to western Toronto grid

What happened

• The Etobicoke Greenway transmission line (230 kV, 6.5 km) was completed in late 2025 and began delivering power in March 2026.

By the numbers

• Capacity: up to 300 megawatts (announced as enough for 300,000 homes).
• Jobs: about 100 supported during construction.
• Budget: project finished $10 million under budget; the savings are funding a recreational trail beside the corridor.
• Procurement: Hydro One reported nearly all materials came from Canadian suppliers.

Where and who it affects

• Runs between the Richview and Manby transformer stations in Etobicoke.
• Intended to strengthen supply for western Toronto and nearby areas of Mississauga and Oakville.

Why it matters

• Adds transmission capacity to meet rising local demand as the GTA grows.
• Uses an existing corridor to limit new community impacts while upgrading reliability.

Other context from the release

• The project was identified in the IESO's Toronto regional plan and is part of broader transmission work, including the planned Toronto Third Line to add further capacity.
