Item - 2025.TTC3.6

The TTC Board:

1. Received this report as a general update on transit expansion projects.

2. Endorsed the Line 1 Growth Trains and a new Line 1 Train Maintenance and Storage Facility as priority projects for funding under the Canada Public Transit Fund and direct the Chief Executive Officer, Toronto Transit Commission to work with the City Manager, City of Toronto on a complete submission and prioritization of transit projects for funding through future funding streams of the Canada Public Transit Fund.

3. Requested TTC staff to provide update in the next Transit Expansion Update report, scheduled for Q4 2025, on the status of discussions with Metrolinx on the TTC’s operations role on the Ontario Line and recommended position to support negotiations of the final Operations and Maintenance Agreement of the line.

As a leading transit operator carrying close to 420 million trips in 2024 and with more than 100 years of institutional knowledge, the TTC is contributing its considerable expertise to expand the public transit network, while placing TTC customers at the centre of all its services.

Promoting sustainable transportation modes through seamless connections is a key objective (3.2) in the TTC’s 2024-2028 Corporate Plan, and the work outlined in this report supports the advancement of rapid transit expansion projects being led by Metrolinx and the City of Toronto (Action 3.2.2). Initiatives being led by the TTC to build network capacity to support growth long-term (Line 1 and Line 2 Capacity Enhancement programs, etc.), also complement rapid transit expansion projects underway. Managing the interface between new expansion projects and base systems needs is central to the work being led by the TTC.

The TTC is working across operations, maintenance, engineering, communications, and planning disciplines with the City of Toronto and Metrolinx to develop the expanded services for Toronto’s transit system: an integrated, accessible, safe transit network seamlessly interfacing with the existing network and connecting TTC customers with all of the mobility options within the city and neighbouring municipalities.

The highlights of this Transit Network Expansion Update report include:

• Line 2 Extension – The TTC is actively collaborating with Metrolinx on the Scarborough Subway Extension (SSE), exploring the option to include the SSE as part of the existing Line 2 ATC procurement. This opportunity will maximize the benefit from the ATC system and the New Subway Trains for the entire Line 2 service on the opening day of SSE and beyond.
• Line 1 Extension and Capacity Enhancement – The TTC and the City are updating the future ridership demand model for the transit network up to 2051. Meanwhile, Metrolinx is delivering the Yonge North Subway Extension (YNSE) from Finch Station to Vaughan, Markham and Richmond Hill. Investment in future capacity enhancement of Line 1 through additional growth trains and a train maintenance and storage facility are being planned and will require future funding. There are ongoing discussions between the TTC and Metrolinx to refine the capacity requirements and interdependencies for both the new fleet and additional facilities for the future state of the extended Line 1.
• Ontario Line – Subject to the New Deal negotiation between the City and the Province, the TTC is working with Metrolinx to confirm the details of the TTC’s roles and responsibilities for the operations of the Ontario Line, including revenue protection, safety and security, customer interfacing, and the network control centre.
• Eglinton East LRT (EELRT) – The EELRT is one of the City's Priority Transit Projects. The TTC is supporting the City by providing planning, engineering, vehicle, operations, and maintenance expertise for the project. Please note that the TTC is working closely with the City and other stakeholders to refine the project scope as well as the roles and responsibilities for this project.
• Waterfront East LRT (WELRT) – The WELRT is another of the City’s Priority Transit Projects. The TTC led the planning and design work for Segment 1 of this project (Union Station to Queens Quay) and is supporting the City and Waterfront Toronto for the ongoing design work for Segment 2 and Segment 3.
