*Forecast for the year 2041
The maintenance and storage facility is a critical part of any public transit operation. It’s where trains are housed and maintained to keep them clean and safe for our customers each and every day.
To support the 388,000 daily trips the Ontario Line is expected to accommodate by 2041, a large site will be needed to store and service the trains.
After an extensive study of nine different sites across the route, the site in Thorncliffe Park was selected because our studies showed that it best met all of the technical needs for the project while clearly demonstrating the least impact to local jobs and businesses.
Work on the facility is anticipated to begin in 2023.
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 would require significant property acquisitions and would impact many jobs.
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 meets all of the technical needs for the project:
At the same time, we determined that we could help impacted businesses and community organizations relocate within the community or nearby if they chose to do so. This was the most critical requirement as we looked for a site in such a built-up urban environment that could accommodate a facility like this.
We're now working one-on-one with property owners and tenants in the area to make sure they continue to thrive and deliver the services their customers and clients rely on each day.
We know how vital local businesses and community organizations are to the fabric of this city and we will ensure they have the supports they need to continue to succeed.
We are now working one-on-one with the leaders of businesses and organizations in the area to make sure they continue to thrive. In some cases this might include working with business owners to relocate to other nearby locations within the community.
The maintenance and storage facility will also bring upwards of 300 new jobs to the community once the Ontario Line is in service.
As teams continue to advance plans for the stations, elevated guideways and maintenance and storage facility in the area, there will be many opportunities for community members to share feedback through 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:
Metrolinx acknowledges that we connect communities by building and operating transit within the traditional lands of the Anishinaabe, the Haudenosaunee and the Huron-Wendat peoples, for whom these lands continue to have great importance.
Treaties between First Nations and governments cover these lands, and the promises contained in these Treaties remain relevant to this day.
Metrolinx and its employees are committed to understanding the history of these lands and the continued impacts of colonization and take responsibility for actions to advance reconciliation.
Metrolinx will continue to seek the knowledge, expertise and experience of Indigenous partners and commits to doing business in a manner that is built on a foundation of trust, respect, and collaboration.
