TTC service changes begin October 12 to support key infrastructure upgrades
October 10, 2025
Starting Sun., Oct. 12, TTC customers travelling through downtown Toronto will experience several service changes as the TTC and the City of Toronto prepare to begin critical infrastructure upgrades, including streetcar track replacements, overhead power network upgrades, and watermain work.
The works are part of a coordinated effort to improve long-term reliability and safety across the transit network. The TTC is working hard to ensure that customers have as many options as possible to get to and from their destinations.
Service changes for streetcar track replacement at the College St. and McCaul St. intersection
The TTC will begin streetcar track replacement at the intersection of College and McCaul streets. During this work, a full road closure will be in effect. Upon completion of the track replacement, the TTC will begin upgrading the streetcar overhead power network, which will involve partial lane reductions.
Starting October 12:
• 506/306 Carlton streetcars will divert both ways via Dundas St. W. between Spadina Ave. and Bay St.
• 94 Wellesley bus service will be increased between Ossington Station and Wellesley Station. Due to ongoing cycle track construction on Harbord St., eastbound buses will continue to divert via Bloor St. W. between Ossington Station and Bathurst St. Westbound buses will divert via Bloor St. W. between Spadina Ave. and Harbord St.
This work is expected to continue through late 2025.
Service changes during coordinated infrastructure upgrades on Queen Street East
From October 12 until Spring 2026, TTC service will be adjusted in preparation for City of Toronto watermain replacement and TTC streetcar track upgrades along Queen St. E. between Broadview Ave. and Davies Ave.
Key changes include:
• Starting October 12, the last eastbound stop for 504B/304 King streetcars will be Distillery Loop. Replacement buses will run both ways between King and Parliament streets and Broadview Station.
• When watermain construction begins, 501/301 Queen streetcars will detour using Dundas St. E. between Broadview Ave. and Parliament St. To serve customers at the affected stops, 503 Kingston Rd buses will replace streetcars, running both ways along Queen St E. between Parliament St and Broadview Ave.
• When watermain construction begins, a 301B Queen bus service will be introduced for overnight service between Broadview Station and Parliament and King streets, via Queen St. E.
Wheel-Trans service will remain accessible in all areas where local traffic is permitted.
