CALEDON, Ont. — Ontario is moving into another major phase of Highway 413 development, launching procurement for the eastern third of the planned GTA corridor and the Highway 427 Extension while awarding a construction management contract for work that includes the Highway 410 Extension.
The provincial government said the eastern-section contract will cover approximately one-third of the Highway 413 corridor. Once awarded, it is expected to become the largest infrastructure procurement ever undertaken by Ontario’s Ministry of Transportation.
“In the face of President Trump’s tariffs, we’re doubling down on our plan to build so we can get people moving and keep Ontario workers on the job,” said Prabmeet Sarkaria, Minister of Transportation. “Highway 413 will reduce travel times across the GTA while supporting more than 6,000 jobs per year during construction and contributing more than $1 billion to Ontario’s GDP.”
Highway 413 Eastern Section Moves Toward RFP
Following the notice of procurement, Ontario plans to issue a request for proposals later this fall covering the design and construction of the eastern section of Highway 413, extending from Highway 400 to west of The Gore Road.
The procurement will also include an extension of Highway 427 north from Major Mackenzie Drive to Highway 413, providing another connection between the planned corridor and the GTA’s existing highway network.
Ontario has separately awarded Infrastructure Partners of Ontario — a joint venture involving Miller Paving, GIP and Amico — the construction manager contract for the Highway 413 central contract, including the Highway 410 Extension.
The planned 9.1-kilometre Highway 410 Extension will run to Highway 413 and is intended to improve connections with Highway 407 ETR, Highway 401 and Highway 403. The province says those links will improve access toward destinations including Burlington, Hamilton, Brantford and Woodstock.
Province Projects Shorter GTA Travel Times
Highway 413 is planned with 11 interchanges at municipal roads across the GTA. According to the province, the corridor could accommodate as many as 300,000 vehicles per day and reduce some trips by up to 30 minutes compared with existing routes.
The government says the project is intended to ease pressure on existing 400-series highways serving Toronto and the regions of Halton, Peel and York as population and freight movement increase.
“Highway 413 is a game-changer for Brampton and Peel Region. Today’s announcement marks another key milestone as our government moves forward on our plan to keep people moving, create jobs, and drive economic growth.”
— Graham McGreggor, MPP for Brampton North
“As we continue to face a trade war with the United States it is more important than ever to build the infrastructure that our communities need. Today’s announcement is an important step to help keep our economy moving.”
— Joseph Racinsky, MPP for Wellington-Halton Hills
Highway Project Positioned as Economic and Jobs Investment
The government is presenting Highway 413 not only as a congestion-relief project but also as part of its broader economic and infrastructure strategy. Ontario estimates construction will support more than 6,000 jobs annually and contribute more than $1 billion to provincial GDP.
“Highway 413 is a key part of our government’s plan to tackle gridlock and keep people moving across the GTA, including here in Vaughan Woodbridge. To build the most competitive economy in the G7, we need the right infrastructure in place. Our government is taking bold action to support our growing communities, create good-paying jobs and strengthen Ontario’s economy by building the infrastructure we need for the future.”
— Michael Tibollo, MPP for Vaughan-Woodbridge
Caledon Mayor Annette Groves also described the highway as important to accommodating the municipality’s continued growth.
“Highway 413 represents a significant investment in Caledon’s future. As our community continues to grow, we need transportation infrastructure that keeps people moving, supports our local economy and takes pressure off our existing road network. Today’s progress brings us another step closer to delivering those critical connections, and I thank the Province for continuing to move this important project forward.”
— Annette Groves, Mayor, Town of Caledon
Ontario’s Broader Highway Construction Program
Work on the Highway 413 program has progressed through several contracts in 2026. In June, the province awarded the detailed design contract for the central section, including the Highway 410 Extension, to the Parsons Inc. / Egis Canada Ltd. Joint Venture.
In July, the program management contract overseeing design coordination and construction was awarded to 413 Continuity Partners, a joint venture of Aecom and WSP.
The project forms part of Ontario’s $31-billion plan to build, repair and expand highways, roads and bridges. Other major projects included in that investment program include the Bradford Bypass and the Garden City Skyway twin bridge.
With procurement for the eastern section now advancing and management work assigned for the central portion and Highway 410 Extension, the province is moving Highway 413 further into its design and construction pipeline as it seeks to expand transportation capacity across the fast-growing GTA.
