The Ontario Line - Neighbourhood Updates - North - Thorncliffe Park & Maintenance and Storage Facility

Thorncliffe Park

After crossing the Don Valley, the Ontario Line will cross Millwood Road and run along Overlea Boulevard on an elevated guideway that will be designed to fit nicely with its surroundings and create opportunities for new public space underneath. This is possible because of the wider street layout, and it avoids the need for disruptive tunnelling activities. Metrolinx will seek community input on designs as part ongoing consultations.

The station located at Thorncliffe Park Drive brings higher-order transit to a community that has been historically underserved by transit. The station and the elevated tracks will be completely separated from vehicles and pedestrians to provide reliable, safe service. An estimated 12,800 people will be to walk to Thorncliffe Park Station in 10 minutes or less by 2041. The new station will also bring people closer to roughly 3,000 jobs in the area.

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

Stats & Facts*

  • 12,800 people within walking distance to the station
  • 3,100 customers will use the station during the busiest travel hour (2,100 getting on and 1,100 getting off the Ontario Line)
  • 500 transfers during the busiest travel hour
  • 3,000 jobs in the area

*Forecast for the year 2041

Maintenance & Storage Facility

The maintenance and storage facility is a vital organ of any public transit operation. It’s where trains will be housed, maintained, and serviced each day to keep them clean and safe for our customers.

An estimated 44 trains will be needed to meet Toronto’s needs when the Ontario Line opens, and the fleet will grow by as many as 10 more vehicles to meet demand for service in the future. We needed a large site to support that growth. The site also had to be the right land configuration.

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 selected because our studies showed that it kept the permanent job impacts to a minimum while meeting all of the technical needs for the project:

  • it is already zoned for industrial use;
  • it is close to the main line, making it quick and easy for trains to go in and out of service; and
  • it is the right land configuration and large enough at 175,000 square metres to meet future needs.

At the same time, we were confident that we could help relocate impacted businesses, community organizations and jobs within the community or nearby, and that’s something we’re still confident about. We have begun working one-on-one with the leadership of small businesses and organizations who will be impacted to make sure they continue to thrive – their continued success is very important to us.

Minimizing impacts to business and community organizations

We know how vital 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 one-on-one with impacted small businesses and organizations to help them relocate within the neighbourhood or nearby, wherever possible. Their continued success is very important to us.

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.

We have already had numerous meetings and discussions with community members in Thorncliffe Park about the maintenance and storage facility. See below for responses to some of the most talked about topics in the community:

We will be seeking feedback on how to best design infrastructure to suit the neighbourhood and exploring opportunities to create new community spaces as part of Ontario Line plans in Thorncliffe Park.

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.
