Class EA Process
The project is being completed following the MTO Class EA for Provincial Transportation Facilities (2000) for a Group “B” undertaking. Group “B” projects are considered major improvements to existing transportation facilities. This project will advance the June 2021 Transportation Environmental Study Report (TESR) Addendum for Highway 401 Interchange Reconstruction at Highbury Avenue.
Prior to the start of construction, a Design and Construction Report (DCR) will be prepared to further document the scope of work, potential impacts, and mitigation measures. A Notice of Study Completion will be issued for the DCR, advising of the start of the 30-day public review period.
