More Transit, More Connections

The Ontario Line will create faster, easier connections between dozens of vibrant neighbourhoods and make it easier than ever to travel within Toronto and beyond.

The 15.6-kilometre, 15-stop subway line will run from Exhibition Place, through the heart of downtown, and all the way to the Ontario Science Centre. It will give people major relief from crowding on the Line 1 subway and other busy transit lines across the city thanks to connections with dozens of other travel options along the way, from regional GO trains, to existing subways, to new light rail transit lines, and more. What it all adds up to is a bigger, more connected transit system that will make it easier to experience the entire region – where and when you want to.

Land acknowledgement

The Ontario Line project takes place on Treaty 13 territory with the Mississaugas of the Credit First Nation. We acknowledge that Metrolinx operates on these lands and has a responsibility to work with the original keepers of this territory and the many diverse Indigenous Peoples living here today. Metrolinx remains committed to engaging with Indigenous Peoples and Nations on the Ontario Line project.

Where Will the Subway Stop?

With fifteen potential stations between Exhibition 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.

More Transit for More Communities - Sooner

The Ontario Line will bring more transit to more in-need communities sooner than previously thought 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, fewer construction impacts – Limiting the amount of tunneling and excavation needed for the project reduces its complexity, which in turn helps reduce construction timelines and property impacts. 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 GO Expansion plans along the existing rail corridor, which reduces the number of construction zones and related impacts in the surrounding community.
  • Faster and more convenient transfers – Customers using above-ground 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 Ontario Line is able to reach transit-deprived communities sooner than previously thought. These include the growing and vibrant neighbourhoods of Flemingdon Park, Thorncliffe Park, Liberty Village and Fort York.

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.

FAQs

You’ve got questions and we’ve got answers. Find out about why we’re above ground in certain areas, how we’re limiting property impacts, our process for property acquisition, and other important topics.

Get Involved

We’re committed to keeping you in the loop. While larger, in-person engagement is on hold we’re still available to answer your questions through email, phone, virtual open-houses, and scheduled meetings.

Construction doesn’t start on any part of the Ontario Line until an environmental assessment report is completed, which includes collecting, analyzing and reporting on public feedback. We’ll be doing several environmental assessments for the Ontario Line, including early works reports to cover specific areas of the alignment where construction will start first. A timeline of their targeted release is outlined below.

Metrolinx releases detour plans to keep people moving during Ontario Line Queen Street construction

Map showing TTC 501 streetcar detour routes to support Ontario Line construction

Even though a lot of subway construction happens underground, there are still impacts at street level – especially near stations. Small parts of Toronto’s Queen Street on either side of Yonge Street are slated for detours to make way for necessary construction work to build a new Ontario Line station at Queen, under the current TTC station. Metrolinx has a plan for keeping people moving, supporting businesses in the area, and building new streetcar tracks for the TTC that will benefit riders long after construction wraps up.

The route has been refined to cross Millwood and Overlea on the northwest corner, rather than the southeast corner of the intersection, which will make construction of the elevated guideway simpler by crossing one street instead of two. The change also addresses feedback from the community by preventing impacts to the iconic Thorncliffe Park sign on the southeast corner of the intersection.


Metrolinx announces more park space for Ontario Line east

June 24 2021

Updated details for the eastern stretch of the Ontario Line include refined plans that reveal the opportunity to create even more green space alongside existing community parks.


Bridging across Toronto’s Don River for the Ontario Line

June 22 2021

As Ontario Line construction proceeds, people will see a new landmark by the waterfront. A bridge, next to the one currently used by GO trains, will carry Ontario Line passengers over the Don River. Metrolinx has released an early works report outlining first steps for building the bridge and giving the pubic an opportunity to comment on the plan.


Locations for Ontario Line station buildings finalized from Osgoode to Corktown

June 17 2021

We’ve been closely following progress on the Ontario Line subway and the impact on transit to and from Toronto’s core. Last week, Metrolinx unveiled the locations for station buildings from Exhibition Station to Queen and Spadina. Today (June 17), we are learning about four more downtown station sites. Two will connect with TTC’s Line 1 subway at University Avenue and Yonge Street while two others will bring subway service to Moss Park and Corktown.
