Ontario has mapped out a preliminary route for a major new highway through the north end of the Greater Toronto Area.

Revived last year after being scrapped by the previous government, the greenfield highway would run southwest from Hwy. 400 in Vaughan, through Bolton, Caledon and Brampton, before turning south and terminating at the junction of Hwy. 401 and Hwy. 407, at the westernmost tip of Mississauga.

Any construction on the project remains several years away, but early plans for the route include up to six lanes, integrated transit with stations for passengers and truck parking.

“The Greater Golden Horseshoe is an economic driver for the province and addressing transportation needs in this region is essential to the competitiveness of our economy,” Caroline Mulroney, Ontario’s minister of Transportation, said in a release. “The GTA West Corridor will help alleviate traffic congestion and improve the movement of people and goods across the province.”


The preferred route for the new 400-series highway released Aug. 7 integrates feedback from public consultations, as well as land use and environmental information. The former Liberal government halted the planning process for the highway in 2018 after an expert panel advised alternative options would deliver “comparable” benefits without occupying the valuable lands northwest of Toronto.

The Ministry of Transportation said the full environmental assessment for the major road project will take until the end of 2022.

    Would it not be more economically, enviromentaly beneficial to purchase 407 and remove or drastically decrease toll pricing? It is to expensive as an alternative to 401. Years ago a cost comparison verified the 407 was redicoulosly
    overpriced. Driving from Buffalo NY to Times Square on toll roads was 70% cheaper than the 160 klm 407. A committe of level minded tranportation proffesionals make this decsion rather than politicians eyeing the graft to come.

    Yes re-purchasing the 407 is the only logical choice or even expanding highway 9. Major Mac has just been expanded and cuts through and connects all the same regions. Why would the province protect the greenbelt then suggest this idiotic plan? Developing a major highway directly through Ontario’s most protected and vulnerable ecological regions which include the Oak Ridges Moraine, Greenbelt, wildlife, conservation areas and fresh water sources is the height of stupidity and ignorance. This will result in contamination of the province’s most sensitive ecological region through road salt and other toxic run offs directly into the immediate and broader water table and farmland along with other vehicular associated pollution. ABSOLUTELY MORONIC! People should object!

  3. Anthony says:

    Actually on second thought; there is a valid argument to be made about it being an additionally good connector as long as it is scrupulously cleared environmentally. And other than the one conservation area on the east end it looks like it manages to stay below the greenbelt lands and avoids highly sensitive ecological areas.
