Moving TTC Subway train enters a station.

City Council has confirmed support for an express subway to Scarborough Centre along the McCowan Corridor, with the station located on the west side of McCowan Road, between Triton Road and Progress Avenue beneath a future extension of Borough Drive. The project will include a bus terminal to serve local and regional routes.


This project is the subject of a Transit Project Assessment Process (TPAP) to satisfy the requirements of the Environmental Assessment Act. As part of the TPAP, an Environmental Project Report (EPR) is being prepared which documents the planning process involved and the details of the Scarborough Subway Extension, including existing and future environmental conditions, the preferred alignment, station location and bus terminal, construction methods, and impacts, mitigation and monitoring measures. The TPAP will include further consultation with the public and stakeholders.
