Starting August 2022, the City of Toronto and Toronto Transit Commission (TTC) will begin a series infrastructure upgrades on Adelaide Street. The upgrades include:

  • Replacement of the 100+ year old watermain and City-owned portion of substandard water services from York Street to Victoria Street
  • Reinstatement of eastbound streetcar track system on Adelaide Street from Charlotte Street to York Street
  • Relocation of the cycle track from the south to the north side of the street from Bathurst Street to Parliament Street. Learn more about the benefits of relocating the cycles track on Adelaide Street.
  • Installation of new bike signals
  • Modification of traffic signal timing
  • Pedestrian safety improvements at various locations from Bathurst Street to Parliament Street.

The watermain replacement and streetcar track reinstatement work is being carried out in advance of the upcoming construction of the Ontario Line subway by Metrolinx. During construction of the Ontario Line, the eastbound 501 Queen streetcar will be diverted to Adelaide Street between York Street and Victoria Street. Learn more about the diversion.

Streetcar track work on Adelaide Street, west of York Street is necessary to allow for TTC route diversions in the downtown core. The remaining streetcar track work on York Street and Adelaide Street will be carried out by Metrolinx.

The City will replace additional sections of watermain on Adelaide Street from Bathurst Street to Spadina Avenue, and Church Street to Jarvis Street. The City will also resurface the road from Bathurst Street to Spadina Avenue and Bay Street to Church Street. The timing of these projects will be communicated here once finalized.

Work Hours: Work will take place from 7 a.m. to 11 p.m., Monday to Friday, with work after hours and on weekends as required.

Phasing: Streetcar track reinstatement / replacement and watermain replacement work will happen concurrently.

  • Crews will undertake streetcar track work in an westward direction from York Street to Charlotte Street.
  • At the same time, crews will replace the watermain from Victoria Street to York Street. Work direction to be confirmed.
  • The timing of the cycle track relocation work will be communicated here once confirmed.

Water Service Disruptions: From time-to-time, the water supply to your property will be shut-off to complete construction; the contractor will provide notice at least 48-hours in advance. Throughout the work, it is recommended that you temporarily disconnect any water treatment systems (i.e. softeners or filters), water-cooled air conditioners or similar plumbing fixtures. In the event you did not receive advance notice, the City may have needed to use an emergency water shut off to complete work.

Preliminary Rail Welding: TTC crews are tentatively scheduled to begin this advanced work in July 2022. A rail welding crew will occupy the two middle lanes on Adelaide Street West between Spadina Avenue and Brant Street. This work involves welding standard lengths of rail into longer strings, which will allow for faster track installation, thereby reducing the construction disruption to local communities. The strings of rail will be stored in the middle lanes just west of Spadina Avenue. The rail pile will be depleted as the track work and new rail installation progresses over the course of the project. Reduced traffic lanes and parking restrictions on both sides of Adelaide Street West will be required through the welding and storage work zone.

Details will be provided in a separate notice closer to the start of this work.

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 contact listed on this webpage as soon as possible.

Accessible Accommodation: 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, inform the contact listed on this webpage.

If travelling through the area, please be aware of:

  • Reduced travel lanes (one shared lane for east bound travel) within the work zones.
  • People cycling can share the travel lane where possible, or dismount and use existing sidewalks.
  • There may be sidewalk restrictions within the construction work areas; however, pedestrian access will be maintained.
  • Access for emergency vehicles will be maintained at all times.
  • Delays and increased traffic on nearby streets. To avoid delays and traffic congestion, travelers NOT destined for this area are advised to use nearby streets and avoid travel on Adelaide Street altogether,
