Three teams have been prequalified and invited to bid on the stations, rail and systems package of works for the Eglinton Crosstown West Extension.

Metrolinx and Infrastructure Ontario (IO) announced the news on September 27.

The teams were selected based on criteria identified in a request for qualifications process that began in March 2024, which included their design and construction experience, as well as their financial capacity to deliver a project of this size and complexity.

The following teams and their prime team members were invited to respond to the RFP:

Integrated Transit Partners

• Applicant leads: Sacyr Canada Inc., NGE Contracting Inc. and Siemens Mobility Limited.
• Primary design team members: Siemens Mobility Limited., Hatch Ltd. Egis Canada Ltd. and Weston Williamson Partners Ltd.
• Primary construction team members: NGE Contracting Inc., Sacyr Canada Inc. and Siemens Mobility Limited.

IO and Metrolinx expect to start working on a development and master construction agreement with a preferred team next summer.

Once that phase is completed, Metrolinx will have the option to sign a contract with the successful team.

The stations, rail, and systems contract includes design and construction of all stations and emergency exit buildings along the extension, fitting the tunnels and elevated guideway with track and signals, and installing and commissioning communications, ventilation and other support systems for the new line.

The contract also includes utility work, road modifications along Eglinton Avenue West to accommodate construction, and changes at Mount Dennis Station that will help connect the extension to future Eglinton Crosstown LRT service.

The 9.2-kilometre Eglinton Crosstown West Extension is being delivered through various public-private-partnership, progressive design-build and traditional procurement contracts, which are being staggered to support their successful delivery.

The subway extension project consists of four major packages of work: stations, rail and systems, the first advance tunnels contract from Renforth Drive to Scarlett Road; the second tunnel, from Jane Street to Mount Dennis Station; and the elevated guideway between Scarlett Road and Jane Street.
