Ontario Opens Highway 427 Expansion

New lanes will reduce travel time by up to 25 minutes during peak periods

KING-VAUGHAN – The Ontario Government is opening a 10-kilometre expansion of Highway 427 from Finch Avenue to Major Mackenzie Drive to help improve traffic flow, reduce congestion and move people and goods safely.

“I am pleased to announce the new and widened sections of Highway 427 will be open to the public on September 18,” said Caroline Mulroney, Minister of Transportation. “As part of our vision for the Greater Golden Horseshoe, our government is investing in highway infrastructure to address congestion and keep up with the growing needs of Ontarians.”

The expansion of Highway 427, which serves as a heavily-used commuter route to the City of Vaughan and neighbouring communities, is expected to save commuters up to 25 minutes of total travel time for a two-way trip during peak periods compared to driving along parallel municipal roadways.

A 6.6-kilometre extension of the highway includes eight new lanes from Highway 7 to Rutherford Road and six new lanes to Major Mackenzie Drive. Three new interchanges at Langstaff Road, Rutherford Road and Major Mackenzie Drive have also been constructed to connect roadways without interruption.

A four-kilometre segment has also been widened to eight lanes from Finch Avenue to Highway 7 along with an upgraded full interchange at Highway 7.

"Our government is expanding subways in York, improving all GO Stations in King and Vaughan, and completing the Highway 427 expansion to reduce congestion and get people moving,” said Stephen Lecce, MPP for King-Vaughan. This expansion is critical to supporting families, commuters and small businesses who need to efficiently move across the GTA without the headache of debilitating gridlock."

Ontario will also be opening one High Occupancy Vehicle (HOV) lane in each direction of Highway 427 to further help improve traffic flow. The new northbound HOV lane will be located between Highway 409 and Rutherford Rd. The southbound HOV lane will start north of Rutherford Road and connect to an existing HOV lane south of Finch Ave.

Improving highways, roads and bridges across the province is a key part of the government's commitment to be a world leader in moving people and goods safely while driving economic growth and job creation by investing in transportation infrastructure.


"Our government continues to make investments in Ontario’s roads, bridges, and highways. By improving infrastructure in our communities, we are improving the quality of life for the people of Ontario. The completed Highway 427 expansion project is an excellent example of our government’s work, as it will enhance our roadways, reduce the amount of time people spend in their vehicles, and give them more time to enjoy their family and friends."

“The Highway 427 expansion will greatly benefit the people of Vaughan-Woodbridge. Not only will it help take vehicles causing crippling gridlock off our local roads, but it will also make our community safer while reducing travel times for commuters and commercial vehicles,” said Michael Tibollo, MPP for Vaughan – Woodbridge. “Most of all, it means the creation of new opportunities like we have never seen before.”
