About the Project:

The Eglinton Crosstown West Extension (ECWE) 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 extension 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. A future connection to Toronto Pearson International Airport is also being studied.

Starting with the approximately 6-kilometre tunnelling phase of work allows a significant portion of the extension to move forward on an accelerated timeline. 

A separate contract will be issued in the future for the balance of the work, which includes building the stations, fitting-out the tunnel and installing and commissioning the systems to put the LRT in service.
