GTA West Project

The Ontario Ministry of Transportation is proposing to construct and maintain a new highway located in the northwest Greater Toronto Area. As proposed, the GTA West Project would be 59 kilometres in length and pass through the municipalities of Vaughan, Caledon, Brampton, and Halton Hills. It would connect highway 400 (between Kirby Road and King-Vaughan Road), to the highway 401/407 interchange area, located near the northern end of highway 403.

 

The project has been referred to publicly as Highway 413. However, the proponent has advised that the project has not yet been assigned a provincial highway number.
