Eglinton Crosstown West Extension

The Eglinton Crosstown West Extension (ECWE) will span 9.2 kilometers from the future Mount Dennis Station on Line 5 (Eglinton) to Renforth Drive, with a total of seven stations.

For more information about the project, or to find information about past and future public engagement, please visit the Metrolinx’s Eglinton Crosstown West Extension project page.

The ECWE is an initiative under the Metrolinx-led Subway Program that will span 9.2 kilometers from the future Mount Dennis Station on Line 5 (Eglinton) to Renforth Drive, with a total of seven stations including two elevated stations at the Jane and Scarlett and five underground stations at Mount Dennis, Royal York, Islington, Kipling, Martin Grove, and Renforth. The ECWE will offer connections to the UP Express, Kitchener Line GO Train service at Mount Dennis, TTC bus services, and MiWay and GO Bus services via the Mississauga Transitway at Renforth Drive.

Plans are also being explored with the Greater Toronto Airports Authority to extend the line another 4.7 kilometres to Pearson International Airport.

The ECWE is being built under four contracts:

  • Advance Tunnel 1 contract for the 6.4-kilometre-long twin tunnels between Renforth and Scarlett stations.
  • Advance Tunnel 2 contract for the approximately 500-metre tunnel between Jane and Mount Dennis stations.
  • Elevated Guideway contract for delivery of the 1.5-kilometre elevated guideway, including guideway structure, piers, foundation, and the Humber River crossing.
  • Stations, Rail and Systems contract for construction of the seven stations and ancillary facilities, fit-out of the tunnel, and systems installation and commissioning.

Construction of the ECWE is currently underway. In April 2022, Metrolinx’s project company (West End Connectors) commenced tunneling of the twin tunnels using tunnel boring machines which will dig from the launch site near Renforth Drive and Eglinton Avenue West towards an extraction shaft at Scarlett Road as part of the package of work for the Advance Tunnel 1 contract. The two tunnel boring machines (TBMs) are continuing their excavation and construction of the twin tunnels and as of May 2023 have tunneled over three kilometers each. Contract award for the Advance Tunnel contract 2 for the 500-metre tunnel between Jane and Mount Dennis stations is anticipated to be announced shortly.

The Request for Proposals (RFP) for the Elevated Guideway contract was released in April 2022 and closed in September 2022. The proposals submitted by the shortlisted teams were evaluated and the contract was award to Aecon Infrastructure Management Inc. in December 2023.  Plans for the Stations, Rail and Systems contract for construction of the seven stations are underway and timelines will be announced in due course.
