More Than Just Rush Hour Relief

The proposed Ontario Line will connect the city like never before. It will be more than just a subway to alleviate crowding on TTC Line 1 – it will be a link to communities across Toronto. From east to west, north to south, from Ontario Place to the Ontario Science Centre, there’s never been a connection in the heart of the city like this one will be. Getting downtown from previously underserved areas will be a breeze, and there will be more trains arriving at stations more frequently. Think of it as downtown relief when you need it.

As we prepare for population increases in Toronto and across the GTA, Metrolinx will be building vital, fast, reliable transit solutions to serve everyone across the region.



Daily Boardings

Where Will the Subway Stop?

With fifteen potential stations between Ontario Place and Ontario Science Centre and potential links to GO Transit and TTC Lines 1 and 2, the Ontario Line will open up the city for all residents to live, work and play the way they want to, when they want.

All alignments, stations, locations, names and quantity of stations are conceptual and subject to change.

Better Service for All Communities

The Ontario Line will connect previously unconnected communities like Thorncliffe Park and Flemingdon Park, with convenient access to transit so people can get to their jobs faster, do errands more conveniently and explore the city easily.

Convenience Across the Line

As the city expands and develops more housing in the region, more residents will likely be within 10-minutes walking distance to the stops on the Ontario Line, making the commute across the city a better experience overall.

Faster Commutes

The Ontario Line will likely deliver up to 40 trains per hour, as frequently as every 90 seconds, providing shorter wait times for customers and faster daily commutes. With quicker travel times and more options to move, you’ll have more time for life, family and things that bring you joy.

Less Crowding

The completed line could provide relief and possibly reduce crowding by an estimated 15% on the busiest stretch along TTC’s Line 1. Crowding may be reduced at numerous stations across the network including:

  • 19% less crowding at Bloor/Yonge Station
  • 17% less crowding at Eglinton Station
  • 16% less crowding at Union Station

Metrolinx and Infrastructure Ontario are working together to deliver the Ontario Line and released the Initial Business Case for the project in July 2019. Planning for the project continues, including due diligence work, further refining the design and engineering work and seeking environmental approvals

On June 2, 2020 Infrastructure Ontario (IO) and Metrolinx issued two Requests for Qualifications (RFQs) for the Southern Civil, Stations & Tunnels contract and the Rolling Stock, Systems, Operations and Maintenance contract - marking the first phase of procurement for the Ontario Line.

On September 17, 2020 Metrolinx published the Draft Environmental Conditions Report. This report characterizes existing environmental conditions within the Ontario Line study area. This report also provides a preliminary description of potential impacts the Project may have on the environment, potential mitigation and monitoring activities.
