Corridor Designation

On November 27, 2025, the Ontario Government designated the Highway 413 under the Public Transportation and Highway Improvement Act (PTHIA) resulting in the release of properties in the Focused Analysis Area and Narrowed Area of Interest that are not anticipated to be impacted by the Highway 413 Project or the Northwest GTA Transmission Corridor.

A green presentation slide titled “Highway 413 Preliminary Design and Assessment of Environmental Impacts.” The word “DRAFT” is diagonally watermarked across the center. Below the title, it says “Draft Environmental Impact Assessment Report” and “December 2025.” At the bottom, there are three logos: Ontario, WSP, and AECOM. A stylized graphic of two curved lines resembling a road or leaf design appears on the right side.

Environmental Impact Assessment Report

On December 1, 2025 the Highway 413 draft Environmental Impact Assessment Report was released for a comment. The comment period closed on January 6, 2026. We thank you for your interest and feedback on the Highway 413 Project. Comments provided during the comment period by the public, federal and provincial agencies, municipal representatives, Indigenous communities, and other interested persons will be reviewed and described in the final EIAR, anticipated to be released in early 2026.

Ministry of Transportation Property Acquisition

The Ministry of Transportation (MTO) contacts affected property owners early in the acquisition process to explain project impacts and offer compensation based on independent appraisals of market value. Owners can conduct their own appraisals for negotiations.

Highway 413 is a proposed highway and transit corridor running through York, Peel and Halton Regions.

The Project includes the 52-kilometre (km) Highway 413 corridor, a 4 km extension to Highway 410, and a 3 km extension to Highway 427 (both facilitating connection to the Highway 413 corridor), for a total of 59 km of new infrastructure.

The highway will have 11 interchanges at municipal roads. Features such as service centres, carpool lots, truck inspection stations, and the potential for electric vehicle charging stations, have been explored as part of Preliminary Design.

The transitway will be a separate corridor running alongside the highway, dedicated for public transit, which will be subject to a separate Environmental Assessment (EA).

The Preferred Alignment

Highway 413 would extend from Highway 400, between King Road and Kirby Road, to the 401/407 ETR interchange near Mississauga, Milton and Halton Hills.
