• 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.
