Eglinton Crosstown West Extension – Advance Tunnel 2 Project

The Eglinton Crosstown West Extension (ECWE) Advance Tunnel 2 Project is the second tunnel package, running between Jane Street and the future Mount Dennis Station. The first Advance Tunnel Project is the first phase of work for the 9.2 kilometre extension of the Eglinton Crosstown LRT (future TTC Line 5). The Eglinton Crosstown West Extension Project will run mostly underground, westward from the future Mount Dennis station to Renforth Drive.

Once complete, the ECWE will connect to different transit services, including the GO Kitchener Line and UP Express train service at Mount Dennis, TTC bus services at transit stops in Toronto, and GO and MiWay bus services via the Mississauga Transitway. Metrolinx is actively collaborating with the GTAA and municipal partners on the proposed alignment from Renforth Drive to the airport, which takes into account the GTAA's plans for a Regional Transit Centre.
