Ontario Line

The Ontario Line

Announced by the Province of Ontario in 2019, the proposed Ontario Line is one of four priority transit projects Metrolinx is leading for the Greater Toronto and Hamilton Area (GTHA). The line will be the largest single expansion in Toronto’s subway history, helping to ease congestion on existing transit lines throughout the city and bring transit to underserviced neighbourhoods.

The proposed Ontario Line will bring nearly 15.5 kilometres of much-needed subway service to Toronto to make it faster and easier for hundreds of thousands of people to get where they need to be each day.

The line will stretch across the city, from the Ontario Science Centre in the northeast to Ontario Place in the southwest.

Current plans for the Ontario Line include 15 proposed stations, including six interchange stations and 17 new connections to GO train lines and existing subway and streetcar lines.

More Transit for More Communities - Sooner

The Ontario Line will bring more transit to more in-need communities sooner than previous plans would have by using a mix of at-grade (surface) track, elevated guideways and underground tunnels. This type of approach comes with many benefits, including:

  • Shorter construction timelines – Limiting the amount of tunnelling and excavation needed for the project reduces its complexity, which in turn helps reduce construction timelines. This will be done by aligning Ontario Line operations within sections of existing above-ground rail corridors in the western and eastern segments of the line, and along elevated structures in the northern segment. In communities like Leslieville, we are also able to streamline our work with existing GO Expansion plans along the rail corridor, which reduces the number of construction zones and related impacts in the surrounding community.
  • Faster and more convenient transfers – Customers using at-grade stations will be able to get where they need to go sooner by avoiding lengthy journeys underground and by taking advantage of faster transfers to other surface transit routes. For instance, an underground East Harbour station would have needed to be built nearly 40 metres underground to reach under the Don River. This very deep station would have added 4.5 minutes to each transfer, adding significant time to people’s commutes.
  • More rapid transit for more communities – The use of existing rail corridors and elevated structures means we can extend the Ontario Line investment farther and reach transit-deprived communities sooner. These include the growing and vibrant neigbourhoods of Flemingdon Park, Thorncliffe Park, Liberty Village and Fort York, which were not included in the former Relief Line South plans. While it will be more than twice as long as the previous Relief Line South proposal, it can be built for a similar cost.

Running along a mix of above-ground and underground tracks is not a new approach --- the TTC has done this with Line 1,Line 2 and Line 3, and many other transit systems have adopted it to deliver superior rapid transit within impressive timeframes. For example, the majority of stations and tracks for world-class transit services like Vancouver’s SkyTrain network and London, England’s Docklands Light Railway system are above ground. Since those systems began in the 80s, the SkyTrain has become the longest rapid transit system in Canada and the Docklands Light Railway system has grown to nearly 40 kilometres’ worth of track.

 

Travel times reduced

The Ontario Line will make it much faster to travel across the city.

From Thorncliffe Park, a commute to the heart of downtown would be 26 minutes instead of the current 42.

It will take five minutes less to get from Pape Station to Osgoode Station, from 25 minutes today to 12 on the Ontario Line.
