Etobicoke Greenway line starts delivering 300 MW to western GTA

What happened

• A new 230‑kV transmission line called the Etobicoke Greenway runs 6.5 km between the Richview and Manby transformer stations in Etobicoke.
• Construction finished in late 2025 and the line began delivering power in March 2026.

By the numbers

• Capacity added: up to 300 megawatts (stated as enough to power 300,000 homes).
• Jobs supported during construction: about 100.
• Budget: completed $10 million under the planned budget; savings directed to a recreational trail.
• Materials: Hydro One procured roughly 98% of materials from Canadian companies.

Why it matters

• The new line increases electricity supply and reliability for western Toronto, southern Mississauga and Oakville as demand in the GTA grows.
• The project used an existing corridor and upgraded Richview and Manby stations to boost capacity while reducing community impact.

Other details from the release

• The project was identified in the IESO's 2019 Toronto Integrated Regional Resource Plan.
• The release also notes planning for a separate Toronto Third Line that would deliver up to 900 MW once built.
