Schedule and Travel Impacts

The project is expected to begin in beginning of September and is expected to be complete by mid October 2025.

TTC Streetcar Track replacement

  • Crews will install new streetcar track at the intersection of King Street and Dufferin Street.
  • TTC crews will test the newly constructed tracks.
  • Crews will also complete sidewalk replacement and tactile plate installation.
  • The intersection will be fully closed to vehicles and cyclists.
  • TTC bus and streetcar service will detour around the intersection.
  • Temporary sidewalk closures may be required. Pedestrian detours and signage will be in place.
  • Access to businesses maintained.

      Work Hours

      Work will take place 24 hours, seven 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 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.

      Deliveries

      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 webpage as soon as possible.

      Accessible Accommodation

      The City’s contractor must ensure safe and accessible walkways and entryways are maintained. 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 City staff listed on this webpage.
