The Ontario Line - Neighbourhood Updates - North

The following maps show refinements to the alignment, or route of the line, and the proposed location of station platforms. Station entrance buildings and initial designs will be shared as new information is available. Teams have been studying how to speed up delivery, reduce building costs, minimize community impacts and improve connections for customers.

The northern portion of the Ontario Line will offer connections to both the Line 2 subway and the Eglinton Crosstown LRT, along with many bus routes in between. It will extend rapid transit service to the densely populated Thorncliffe Park and Flemingdon Park neighbourhoods, reducing commute times and congestion for local residents. For example, a trip from Thorncliffe Park to King and Bay that currently takes 42 minutes is expected to take 26 minutes.

  1. Connecting to Line 2 at Pape Station, the Ontario Line brings customers to the vibrant Greektown neighbourhood and its many restaurants, shops and markets, rich in culture and hospitality. By positioning the Ontario Line station out of the street and straddling Line 2, impacts to area traffic during construction are reduced and customers will have smoother transfers between the lines once the Ontario Line is operational.

By giving Line 2 riders another way to get downtown, the Ontario Line is expected to reduce overcrowding at Bloor-Yonge Station by 19%. It is also expected to reduce crowding on the busiest section of Line 2 by 22%.

Work is anticipated to begin after financial close for the Northern Civil, Stations and Tunnel procurement package.

Due to the complex nature of constructing this interchange station, some work may be advanced as early works.

  1. Arriving at Cosburn, the subway brings customers to Pape Village and East York. By positioning the station west of the street, fewer of the buried utilities will need to be relocated, including the recently upgraded water main. While the property requirements for this approach are comparable to what would have been needed if the station were built directly under the street, imposing fewer construction impacts on area traffic is an added benefit. Property requirements are still being finalized. Metrolinx will only acquire property necessary for the project and strive to minimize the impacts of construction.

Work is anticipated to begin after financial close for the Northern Civil, Stations and Tunnel procurement package.

map of the Don Valley Crossing

This underground section will emerge from the southern embankment of the Don Valley at Minton Place, west of the Leaside Bridge, on an elevated structure that will connect it to Thorncliffe Park and points north.

Using modern bridge construction techniques, the visual and environmental impacts of the structure will be minimized.

  1. After crossing the valley, the Ontario Line crosses Millwood Road and runs along Overlea Boulevard on an elevated guideway. This is possible because of the wider street layout, and it avoids the need for disruptive tunnelling activities.
  2. The station located at Thorncliffe Park Drive brings higher-order transit to a community that is expected to grow significantly in the years to come.
  3. Instead of the original plan to proceed along Overlea Boulevard after the station, the Ontario Line will turn to the north and run adjacent to the nearby hydro corridor, on its way north which reduces community impacts and is a better fit for the neighbourhood.
  4. The guideway will feature a design that fits into its surroundings. Concepts will be shared in the coming months.

Work is anticipated to begin after financial close for the Northern Civil, Stations and Tunnel procurement package.

The Ontario Line’s maintenance and storage facility will be located in the southeast portion of the Leaside Business Park.

This will be the beating heart of the Ontario Line, where trains will be housed, maintained, and serviced each day. In order to provide the congestion relief, the city needs a site of 175,000 square metres – about the size of 24 soccer fields. This will accommodate as many as 200 train cars at opening and up to 250 train cars to support future growth.

Site selection

We studied the following nine options in close collaboration with City of Toronto staff. No vacant land exists in the city to accommodate a maintenance and storage facility. All options required significant property acquisitions and would have impacted many jobs.

nine locations under consideration for msf site

  • Site 1 – Wicksteed: Large enough; location close to the main line; would require relocation of significant number of jobs/businesses, some of which may not be able to relocate within the city.
  • Site 2 – Overlea: Large enough; location close to the main line; would require relocation of significant number of jobs.
  • Site 3 – Leaside: Large enough; would require relocation of critical services (Canada Post distribution centre) and significant number of jobs; would require permanent road closure/diversion and larger land area to accommodate the additional length needed for underpass/overpass to cross CP rail corridor.
  • Site 4 – Flemingdon hydro corridor: Not large enough; would require relocation of hydro power lines and permanent road diversion; would impact community park space.
  • Site 5 – Science Centre: Not large enough; poor location near major interchange between Ontario Line and Eglinton Crosstown LRT; would impact plans underway for mixed-use development, including affordable housing and new school.
  • Site 6 – Celestica: Poor location near major interchange between Ontario Line and Eglinton Crosstown LRT; would impact advanced plans for mixed-use development, including affordable housing and major new municipal community centre.
  • Site 7 – Wynford: Not close to main line; would require relocation of significant number of jobs, businesses/ community organizations; higher operational costs.
  • Site 8 – Railside: Would require relocation of several places of worship, significant number of jobs/businesses, community centre; farther from Ontario Line, requiring additional track and tunnel portal or bridge; higher capital and operational costs.
  • Site 9 – Greenwood Yard: Not large enough; would have major impacts on TTC operations during and after construction; would lead to schedule delays and significant cost increases.

After extensive study, a hybrid of sites 1 and 2 in the southeast portion of the Leaside Business Park was chosen because the area:

  • is already zoned for industrial use;
  • is close to the main line, making it quick and easy for trains to go in and out of service;
  • is large enough to meet future needs;
  • minimizes community impacts; and
  • minimizes impacts to businesses.

Minimizing impacts to business and community organizations

We know how important local businesses and community organizations are to the fabric of this city and we will do all we can to ensure they have the supports they need to continue to thrive. We are working with impacted property owners and tenant businesses to help them relocate, wherever possible.

Our guiding principle is to minimize impacts to businesses, organizations, employees and residents as we bring quick and reliable transit to the community.

Engaging with the community

As teams continue to advance plans for the stations, elevated guideways and maintenance and storage facility in the area, there will be numerous opportunities for community members to share feedback through environmental assessments and numerous community meetings.

Work on the facility is anticipated to begin in 2023, after a contract is awarded for the Rolling Stock, Systems, Operations and Maintenance package of work.

  1. From the Maintenance and Storage Facility, the line continues along the elevated guideway, turning north at Don Mills Road to a station that serves the Flemingdon Park community. The station, located on the west side of Don Mills just north of Gateway Boulevard, has been positioned in an existing parking lot to reduce community impacts.

This station will help meet an already significant demand for transit. On weekdays, 28,900 TTC riders take the 25 Don Mills bus – the seventh-most used regular bus route in the city – and 12,800 take the 100 Flemingdon Park bus.

Work is anticipated to begin after financial close for the Northern Civil, Stations and Tunnel procurement package.

map of the line segment containing the Science Center
  1. A new transit hub at the Science Centre Station will connect the Ontario Line to the Eglinton Crosstown LRT and frequent local and express bus services from the north. The station is elevated, located at the northeast side of Don Mills Road. This positioning will allow for better integration with the future TTC bus terminal at this site and potential future extension of the Ontario Line to the north.
  2. Tail tracks, north of the stations, will provide space for the storage of vehicles and protect for future expansion.

Work is anticipated to begin after financial close for the Northern Civil, Stations and Tunnel procurement package.
