Ontario Advancing Work on Highway 413

Province extending Highway 410 to connect with future corridor

CALEDON — The Ontario government is issuing a Request for Proposals (RFP) to design an extension of Highway 410 that will connect to the future Highway 413, marking another milestone in the province’s plan to better connect the regions of Halton, Peel and York, getting drivers out of gridlock and shortening travel times by up to 30 minutes per trip. The construction of Highway 413 will support more than 6,000 jobs per year and contribute more than $1 billion to Ontario’s annual gross domestic product.

“Our government is making historic investments in highway infrastructure to get drivers in the GTA and Ontario out of gridlock,” said Prabmeet Sarkaria, Minister of Transportation. “Building Highway 413 will help protect Ontario against U.S. tariffs and global economic uncertainty by improving the movement of people and goods and keeping more than 6,000 workers on the job during construction.”

The province is seeking proposals to design a 9.1-kilometre extension from Highway 410 at Countryside Drive north to Highway 413, and from Highway 413 west to Highway 10. This extension will give drivers a direct link between the two highways, cutting travel times and relieving gridlock on local roads. Once complete, Highway 413 will extend from Highway 400 in the east to the Highway 401/407 interchange in the west.

The extension of Highway 410 is one of several projects underway as work begins on the new Highway 413 corridor. In August, Ontario awarded the first two construction contracts to build Highway 413. In addition, the province recently completed upgrades to the Highway 401/407 interchange, the western terminus of Highway 413.

Extending Highway 410 to connect with the future Highway 413 supports the province’s more than $220 billion plan to build, which is the largest infrastructure plan in Canadian history, keeping Ontario workers on the job as the province faces down the impact of tariffs and economic uncertainty. This plan includes $30 billion in investments to build and upgrade roads, highways and bridges across Ontario, including Highway 413, the Bradford Bypass, the twinning of the Garden City Skyway and widening of major highways such as Highway 401 and the QEW.

Quick Facts

  • The province has also made refinements to the Northwest GTA Transmission Corridor and will release lands that are no longer required for future transmission infrastructure. The transmission corridor is being co-located with Highway 413, and will host major infrastructure projects to support Energy for Generations, the government’s long-term plan to deliver reliable, affordable and secure energy to create good-paying jobs and power Ontario’s future.
  • In accordance with the Highway 413 Act, 2024, a draft Environmental Impact Assessment Report has been prepared to describe the preliminary design of the Highway 413 project and is now available for public comment.
  • Last year, the Reducing Gridlock, Saving You Time Act received Royal Assent, allowing the province to accelerate construction of Highway 413, the Bradford Bypass and the Garden City Skyway twin bridge.
  • Gridlock costs Ontario $56 billion each year, according to a report from the Canadian Centre for Economic Analysis. If left unchecked, that cost could grow to $108 billion by 2044.
