There are two main challenges that the Relief Line could address:

1. Existing Crowding and Congestion

Existing levels of crowding and congestion will continue to deteriorate without transit expansion

  • Transfer between Bloor-Danforth and Yonge Subway Lines is seriously constrained
  • Yonge Subway is currently overcapacity south of Bloor Station
  • Capacity improvements now underway on Line 1 (YUS) include:
    • New “Toronto Rocket” Subway Trains (+10% capacity)
    • Automatic Train Control (+25% capacity)
  • Crowding on the King and Queen Streetcar is deteriorating the quality of transit service

2. Future Demand

Additional transit capacity is needed to meet anticipated demand on the Yonge Subway Line

  • Even with planned and funded improvements to Line 1 by 2031 additional investment will be needed to accommodate growth
  • Future extension of the Yonge Subway north will increase ridership
  • Continued growth in the Downtown will attract ridership
    • 51% of GDP
    • 33% of jobs (446,000)
    • 557,000 m2 of office space being planned and under construction

Relief Line Addresses Crowding and Congestion

The initial phase of the Relief Line would be the TTC’s third busiest route

The Relief Line will ease congestion at Bloor-Yonge station by providing an alternative route to downtown

Transfers at Bloor-Yonge station will be reduced by 30% and Line 1 (Yonge) riders will be reduced by 12%

The relief Line reduces crowding on the downtown streetcar system

Up to 35% of streetcar riders coming into downtown from the east on the King or Queen routes will be redirected to the Relief Line
