Environmental Assessment

The Minister of the Environment with Cabinet’s concurrence approved the Ministry of Transportation’s (MTO) Highway 404 Extension Environmental Assessment (EA). This EA approval will allow the MTO to proceed to the design and construction stage for a new 45 km four-lane extension to Highway 404 with controlled access extending northerly from Davis Drive to Durham Rd. 23, and a 9 km transition section between Durham Rd. 23 and Highway 12. The design and construction of the highway will be subject to the MTO's Class Environmental Assessment for Provincial Transportation Facilities. This process provides for public consultation on the design and construction of the highway. It is anticipated that the highway will be constructed in stages over a number of years, to reflect financial constraints and traffic demands.
