The City of Toronto has completed the planned construction work on College Street/Carlton Street between Bay Street and Church Street, including combined sewer and streetcar track infrastructure improvements.
TTC will continue with remaining overhead work along the corridor through November. Please see the Construction Schedule & Travel Impacts section below for details.
This work was required to bring the combined sewer and streetcar track infrastructure to a state of good repair and is part of the Council-approved 2026 Capital Works Program.
Please visit ttc.ca/CollegeStreet for all TTC diversion information.
The work area is along College Street and Carlton Street from just west of Bay Street to Church Street to the east.

Work on this project will take place 24 hours a day, 7 days a week. Excavation activities and heavy breaking will be carried out at various times throughout the day. All concrete breaking activities will occur between 7 a.m. and 11 p.m. Concrete breaking work is the most disruptive and will typically last the first one to two days for each phase of the construction. Around-the-clock work during rail installation by TTC is required to preserve the integrity and quality of new rail and concrete. Overnight rail work by TTC may consist of moving new rail into position, rail installation and rail welding / grinding.
The City has been working with businesses and property management representatives to accommodate delivery and loading activities during construction. If you have not yet discussed your delivery needs with the project team, please contact the staff person listed on this web page as soon as possible.
The City’s contractor must ensure safe and accessible walkways and entryways are maintained for everyone during construction. Any temporary access disruptions will be communicated as soon as possible. If you experience a disruption, have a specific access need or related accommodation request, contact the person listed on this web page.
During Phase 1, due to the full closure of the College Street and
Bay Street intersection, cyclists travelling northbound and southbound may detour via Grenville Street, Elizabeth Street, and Gerrard Street West. This detour may be used in both directions.

The project began in March 2026 and City construction was completed on October 28, 2026.

To accommodate FIFA World Cup 2026™, the contractor fully demobilized from the site to help manage congestion and minimise disruptions.



Once construction is complete, TTC crews will test the newly constructed tracks.
College Street from Bay Street to Yonge Street
