College Street and Bay Street
College Street and Bay Street Track Renewal and Overhead Upgrades
What we are doing and why
Construction began in early March and is currently underway. A planned pause in construction will take place from mid-April to end of July 2026. Overall work is expected to be completed in December 2026.

TTC Service impacts
The intersection of College and Bay has been fully closed since March 2 to support construction activities. As a result, TTC has adjusted service to 506/306 Carlton streetcars and 19 Bay buses.
TTC service adjustments remain in effect while work such as track replacement, overhead upgrades, and commissioning work continues at College and Bay.
Current service changes (as of March 23)
506/306 Carlton streetcars are diverting both ways via McCaul Street, Dundas Street, and Parliament Street to regular routing.
A 506/306 Carlton bus replacement service has been introduced, operating between Spadina Station and Broadview and Gerrard via:
- Eastbound: Spadina, College, University, Gerrard, Yonge, Carlton, Parliament, Gerrard
- Westbound: Gerrard, Parliament, Carlton, Yonge, Wellesley, Queens Park, College, Spadina
19 Bay buses are diverting via:
- Northbound: Gerrard, Yonge, Wellesley
- Southbound: Wellesley, Queens Park, University, Gerrard
Regular 506/306 Carlton streetcar service and 19 Bay bus service are expected to resume in May and during FIFA World Cup 2026™.
Additional diversions will be required when work resumes on College/Carlton for Phases 2 and 3 after FIFA World Cup 2026™. TTC will communicate these changes at a later date.
Related Construction Activities
As part of this project, and while streetcar service is diverted, TTC and City crews may also carry out related streetcar repairs in nearby areas. This work helps prepare the corridor for current construction and upcoming phases, and is coordinated to take advantage of the existing closure.
These activities may include inspections, overhead upgrades, rail and concrete repairs, and other enabling work to support the overall construction project. Completing this work at the same time is intended to reduce the need for future disruptions.
Overhead Upgrades
Throughout this project, TTC crews are actively upgrading and commissioning streetcar overhead infrastructure in the area while streetcars are diverted. Work may take place both during day and night shifts and will involve TTC overhead trucks with hydraulic equipment. While efforts will be made by the crew to keep noise to a minimum, beeping sounds when the trucks are backing up will be audible. Equipment lights may also be noticeable.
Thank you for your patience as we improve Toronto’s transit infrastructure.
