Langstaff Road Notice of Completion January 2022
Municipal Class Environmental Assessment Study of Langstaff Road in the City of Vaughan
The Regional Municipality of York has completed a Schedule ‘C’ Municipal Class Environmental Assessment Study for the proposed improvements to Langstaff Road from Weston Road to Highway 7. The study reviewed the growth in the area and identified improvements needed to accommodate existing and future transportation needs of this area as part of the Regional road network.

The study recommends improvements including widening Langstaff Road to six lanes between Weston Road and Dufferin Street, providing sidewalks and cycle tracks and a proposed future connection across the CN MacMillan Rail Yard and a proposed separation of the road and rails at the Metrolinx GO Barrie Line. Improvements associated with the Highway 400/Langstaff Road interchange are subject to a future highway corridor study.
York Region has prepared an Environmental Study Report (ESR) documenting the study process, consultation efforts and the recommended plan. This Notice of Completion places the ESR on the public record for a 30-day review period, beginning January 13, 2022. The ESR can be reviewed and downloaded at york.ca/LangstaffStudy
