  • Applicant Lead: STRABAG Inc.

Teams have been invited to respond to the RFP and will begin preparing their proposals that detail how they will deliver the project. Upon evaluating the proposals received, IO and Metrolinx expect to award this contract in early 2023.

The Province is also issuing an RFP for the elevated section of the Eglinton Crosstown West Extension. The elevated section will run from just west of Scarlett Road to just east of Jane Street. Metrolinx expects to award this contract later in early 2023.

The Eglinton Crosstown West Extension (ECWE) is a 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.

The ECWE is one of the priority transit projects announced by the Province in 2019 as part of the New Subway Transit Plan for the Greater Toronto Area. The other three projects include the Scarborough Subway Extension, the Ontario Line and the Yonge North Subway Extension.
