Metrolinx and Infrastructure Ontario have issued a Request for Qualifications to find a team that will design, build, and finance tunnels to run between Toronto’s Jane Street and the future Mount Dennis Station on the Eglinton Crosstown West Extension.

Once built, the Eglinton Crosstown West Extension will extend the Eglinton Crosstown light rail transit (LRT) project another nine kilometres further west into Mississauga.

The route will run underground from Renforth Drive to Scarlett Road, where it will then run on elevated tracks to Jane Street before heading underground again to connect with Mount Dennis Station.

Work is already underway to build the tunnels between Renforth Drive and Scarlett Road; the request for qualifications released today is for the tunnelled section at the eastern end of the Eglinton Crosstown West Extension.

A request for qualifications is the first step in the procurement process for a major project like this.

It’s used to identify project teams that have the right experience and abilities to take on the project. Qualified teams are then asked to participate in the next step of the procurement – the request for proposals (RFP) — which Metrolinx expects to release next spring.

“It’s really exciting to see the progress being made on the Eglinton Crosstown West Extension,” said Joshua Engel-Yan, Metrolinx program sponsor for the Eglinton Crosstown West Extension.

“Every milestone we reach brings us closer to bringing higher-quality rapid transit to transit riders in Mississauga and Etobicoke, and to people across the region.”

There are more of these kinds of milestones on the horizon, with procurement for the elevated section stations, as well as rail and systems contracts still to come.

Work continues at Renforth tunnel launch site. Since breaking ground in July, the tunnel launch site at Renforth Drive has been a busy place.

Once it’s complete, the launch shaft will be 80 metres long, 20 metres wide and 17 metres deep to accommodate the tunnel boring machines (TBMs) that will be lowered into it in spring 2022.
