PEEL REGION – The Ontario government has announced it is proposing to reduce the boundaries of the Northwest GTA Transmission Corridor and release lands that are no longer required for protection.

A release states this news means the government is reducing the lands held for the transmission and highway corridors by approximately 40 per cent.

The proposed corridor along Highway 413 is based on a study launched in 2019 to identify a viable route for future transmission infrastructure.

“The refined corridor reflects detailed technical analysis to identify the narrowest path capable of supporting both 230 kV and 500 kV transmission lines, while preserving flexibility for future transmission designs,” the release notes. “The study prioritized co-location with Highway 413, minimizing impacts on natural areas, and avoiding built-up communities.”

This proposal and updated maps are now available for public comment on the Environmental Registry of Ontario. The Ministry of Energy and Mines and the Ministry of Transportation are expected to announce their finalized land use plans and release surplus lands in December.
