Yonge Subway Extension

Yonge Subway Extension

The planned Yonge subway extension will extend 7.4 kilometres north from Finch Station to Highway 7. This critical rapid transit link will include five stations at Cummer/Drewry, Steeles, Clark, Langstaff/Longbridge and Richmond Hill Centre. Intermodal terminals will be located at Steeles and at Richmond Hill Centre and 2,000 commuter parking spaces will be at Highway 407.

status

  • The Yonge Subway Extension is ready to move to full engineering and construction.
  • In April 2009, the Ontario Ministry of the Environment unconditionally approved the Environmental Project Report [and addendum] for the Yonge subway extension.
  • In 2012, the Conceptual Design Study that looked at specific engineering elements was completed and approved by the Toronto Transit Commission and The Regional Municipality of York.
  • In 2015, Metrolinx released the findings of a Yonge Relief Network Study, and recommended advancing the Yonge Subway Extension with preliminary engineering. We are currently awaiting a funding announcement from the Province of Ontario before moving forward on this recommendation.
  • Engineering and construction will take approximately 10 years, and during preliminary engineering a more detailed schedule will be confirmed.

ridership & capacity

Metrolinx’s Yonge Relief Network Study analyzed options for crowding relief to the existing Yonge Subway line by examining new local and regional travel opportunities and improving mobility across the GTHA.

Key findings include:

  • Today, the Yonge Subway line is operating at +11% over capacity.
  • Significant relief to the Yonge Subway line will be achieved through already committed transit improvements, including the TTC’s automatic train controls [adds 36% capacity], new signals [adds 10% capacity], six-car trains [adds 10% capacity], the Toronto-York Spadina Subway Extension [adds 8% capacity] and Regional Express Rail/SmartTrack.
  • The Yonge Subway Extension can be built – with the capacity improvements noted above added during the 10-years of engineering and construction, the Yonge Subway line will be running under capacity by 2031.
  • The Downtown Relief Line has become a long-term project that will not be needed until after 2031.
  • A recommendation to “Direct staff to work in consultation with York Region, City of Toronto and the TTC to advance the project development of the Yonge North Subway Extension to 15% preliminary design and engineering.”
  • Only a subway can service the potential future daily ridership of 165,000 [two people per second] – even today, over 2,500 bus trips per workday are needed to serve the current demand.

benefits

  • Completes a critical missing link in the regional rapid transit system of the GTHA, making an easy and seamless connection between regions. To read about why the Yonge Subway extension to Highway 7 is considered a top priority, see The Missing Link.
  • Fuels a proposed 23,530 residential units and 24,990 jobs at the Richmond Hill/Langstaff Urban Growth Centre at Highway 7 and Yonge Street.
  • Produces a lasting economic stimulus and creates jobs.
  • Aligns with plans for growth and rapid transit in the GTHA, integrating with Regional Express Rail, building on the existing investment of more than $3 billion in York Region’s rapid transit, and meeting the Province’s smart growth objective of a transportation hub at Yonge and Highway 7.
  • Almost eliminates the 2,500 bus trips per workday currently serving the demand between Finch and Highway 7.
