Teston Road IEA Study

In the City of Vaughan

The Regional Municipality of York completed a Comprehensive Environmental Assessment (EA) Study in the City of Vaughan to identify road improvements near Teston Road. The study area is bounded by Kirby Road, Bathurst Street, Major Mackenzie Drive West and Highway 400. 

As required under section 6.2(1) of the Environmental Assessment Act and according to the Terms of Reference approved by the Ministry of the Environment, Conservation and Parks on December 20, 2018, York Region has submitted its environmental assessment to the Ministry of the Environment, Conservation, and Parks for review and a decision.

The Teston Road Area EA Study aims to generate solutions for transportation challenges and opportunities. The project considered improvements for vehicles, pedestrians, cyclists and transit in the study area. 

Recommended Improvements

  • Widening Teston Road from two to four lanes west of Keele Street to Rodinea Road and from Dufferin Street to Bathurst Street 
  • Extending Teston Road as a new four-lane roadway from Rodinea Road to Dufferin Street; a modified short-term solution is proposed along Teston Road (Keele to Dufferin) with a multi-use path 
  • Constructing an at-grade GO Rail crossing on Teston Road east of Keele Street with property protection to separate the road and tracks in the future, if needed 

As required under the Ontario Environmental Assessment Act, York Region has released the CEA Study Report for public review.
Notice of Submission

The Comprehensive Environmental Assessment Report is available below for review and comment from Friday, February 27 to Friday, April 17, 2026. The Teston Road IEA Study will be submitted to the Ministry of the Environment, Conservation and Parks for review and approval.
