Ferrovial Construction Canada Inc. and VINCI Construction Grands Projects are undertaking the design, build, and finance the Ontario Line Southern Civil, Stations, and Tunnel (South Civil) package.

As Ontario Transit Group, we are now mobilizing our design and construction crews, with major works. The South Civil contract is anticipated to be completed in 2030.

The project will strengthen Ontario’s economy by supporting an estimated 1,500 jobs at the peak of construction.

What is the project?

• A six-kilometer tunnel and associated tunnelling works from Exhibition to Don Yard portal (west of the Don River).
• Stations:
  • One above-ground station to be integrated with the existing GO Transit Exhibition Station.
  • Two underground stations to be integrated with the existing TTC Osgoode and Queen subway stations.
  • Four new underground stations (King/Bathurst, Queen/Spadina, Moss Park, Corktown).

The benefits to Ontario!

Faster, more frequent, and reliable access to rapid transit with more than 227,500 people will live within a 10-minute walk of an Ontario Line station.

• Improve the quality of life for commuters by reducing daily travel time.
• Reduce crowding on the existing Line 1 (Yonge-University) subway.
• Up to 57,000 more jobs accessible by transit (in 45 minutes or less) for Toronto residents.
• Economic and community growth along the future transit line and thousands of job opportunities annually during construction.
• Reduction in traffic congestion, greenhouse gases, and fuel consumption by providing an alternative transportation option.
