Eglinton Crosstown West Extension Tunnel

Expanding Toronto’s Future Rapid Transit Network

The Eglinton Crosstown West Extension is a major public transport project that will extend Toronto’s future light rail transit network by 9.2 kilometres and add seven new stations. The extension will create a continuous rapid transit corridor connecting eastern Toronto with the city centre and the neighbouring city of Mississauga, improving mobility across the wider metropolitan region.

STRABAG’s Canadian subsidiary was awarded the approximately €175 million (CAD 255 million) Design-Build-Finance contract for the design and construction of the eastern underground section of the extension. The project further strengthens STRABAG’s presence in the Canadian infrastructure market and builds on the company’s successful delivery of the Highway 401 Rail Tunnel Project.

A key component of the contract is the construction of a 500-metre tunnel that will connect the future terminus at Mount Dennis Station with the elevated section of the extension. The tunnel is being excavated using the Sequential Excavation Method (SEM), enabling safe and efficient construction in a densely developed urban environment. 

Scope of Work

• Design and construction of the eastern underground section of the extension 
• Construction of a 500 m tunnel using the Sequential Excavation Method (SEM) 
• Construction of a launch shaft and an extraction shaft 
• Delivery of a temporary bi-directional cycle track
