Improving Network Capacity

The Relief Line will provide relief to the Toronto transit system and provide residents with new rapid transit service into the downtown core from the surrounding inner suburbs - The line is also required to support the planned Yonge Subway extension to Richmond Hill - Many riders will shift to utilize the Relief Line, leaving room on the Yonge-University-Spadina line for those making trips from Midtown Toronto, Scarborough, North York, and York Region

By 2031, it is projected that the Relief Line will serve up to 107 million riders - Several improvements are currently underway to improve capacity along the Yonge-University-Spadina line - In 2007, Metrolinx committed approximately $300 million to pay for the new signalling technology required to increase capacity on the Yonge-University-Spadina line - The new signalling system allows more trains to run each hour - To expand capacity even further, other changes are necessary, such as passenger-flow improvements at Bloor-Yonge station - These improvements will reduce train waiting times and improve passenger connections between the Yonge-University-Spadina and the Bloor-Danforth subway lines

Further work is necessary to better define the scale and scope of the Relief Line, and Metrolinx is working in close collaboration with municipal partners to advance the project

Metrolinx is currently undertaking a Relief Line Network Study that will examine several options, while considering how to leverage investment and provide net benefits to the region as a whole The Relief Line Network Study is being coordinated with phase two of the TTC’s Downtown Rapid Transit Expansion Study to evaluate potential Relief Line alignments as well as work on the City of Toronto’s Official Plan review, with York Region also providing input

The study will build on prior work completed by Metrolinx and the TTC, including phase one of the TTC’s Downtown Rapid Transit Expansion Study, the Union Station 2031:  Demand and Opportunities Study, and multiple Benefits Case Analysis (BCA) reports related to the Yonge North and Relief Line projects

Specific recommendations emerging from the study would be further refined through a Benefits Case Analysis (BCA), and be subject to any applicable environmental assessments, and necessary Metrolinx and government approvals, before being finalized - This project is currently unfunded
