Providing more connections for Toronto commuters

Gridlock costs Toronto an estimated $6 billion each year. Bechtel is working with the Toronto Transit Commission (TTC) to extend the city’s subway system.

Prior to Bechtel joining the project, it had been overdue and over budget. The TTC brought in Bechtel in 2015 to get the project back on track.

The best decision of my 27-year career is bringing in Bechtel to manage the last 30 percent of the Spadina Subway extension contract.

TTC Chief Executive Officer, Andy Byford.


  • The 5.3-mile (8.6 kilometer) extension includes six new stations with several intermodal connections
  • The project will extend the western end of the existing Spadina Subway Line 1 across Toronto city boundaries into the region of York
  • The extension project will help alleviate gridlock, which costs Toronto an estimated $6 billion each year
  • The two main techniques used to build the extension tunnels are tunnel boring machines and Sequential Excavation Method
  • Since 1942 Bechtel has completed over 800 studies and projects in Canada

Fast facts

  • The six new subway stations under construction include a stop in the center of the York University campus
  • The two main techniques used to build the subway extension tunnels are tunnel boring machines and Sequential Excavation Method (SEM)
  • The method used to build the subway extension's deep concrete box stations is 'cut and cover' construction
  • To encourage commuters to use the subway system, 2,900 parking spaces are being built at three stations

We are providing program management services, as part of an integrated delivery team with our customer, for the last two years of this critical project. The Toronto-York Spadina Subway Extension Project will extend the western end of the existing Spadina Subway Line 1 across Toronto city boundaries into the rapidly growing Region of York. 

The 5.3-mile (8.6 kilometer) extension includes six new stations with several intermodal connections including GO commuter rail, city bus service, bus rapid transit, and commuter parking. It also requires four new power substations to supply the subway.Watch a timelapse video of the new railway.

Supporting Canada since 1942

Bechtel has been working in Canada for nearly three quarters of a century and has completed more than 800 studies and projects that contribute the country’s infrastructure. In addition to our work on the Toronto-York Spadina Subway Extension, other ongoing projects include the Keeyask Generating Station, the Edmonton Light Rail, and the Kitimat Aluminum Smelter.

We build rail

Bechtel has delivered more than 6,200 miles of railways and completed 35 metropolitan rapid transit systems. Bechtel has worked on many of the largest and most complex railway projects in the world including:

  • Athens Metro: Managed an engineering and construction consortium of 22 companies to complete the delivery of two new subway lines in time for the 2004 Summer Olympics.
  • Channel Tunnel: Bechtel managed this ambitious project to a successful completion after severe cost, schedule and safety problems threatened to derail the world’s longest undersea tunnel.
  • London Underground Upgrade: The Jubilee Line Extension—one of the largest London underground additions in 25 years—was severely behind schedule. Bechtel was hired to provide a fast-track push to meet the Millennium deadline and completed the project in just 14 months.
