About the 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.

The Eglinton Crosstown West Extension is being delivered in separate procurement contracts:

  1. A first advance tunnel between Renforth Drive and Scarlett Road.
  2. A second advance tunnel between Jane Street and Mount Dennis Station.
  3. Elevated guideway between Scarlett Road and Jane Street.
  4. Stations, Rail and Systems.

Demonstrating Value

  • The project is being delivered using a Design-Build-Finance (DBF) model. Key benefits of a DBF model include significant risk transfer to the private sector over the life of the project agreement, greater cost and schedule certainty and greater potential for design and construction efficiencies and innovation.
  • Based on precedent project experience, a DBF procurement model typically has delivered a value for money savings in the range of 10% to 15% compared to undertaking the same projects using traditional delivery models.
