The City’s contractor has completed reinstating TTC streetcar tracks from Spadina Avenue to York Street, and lane restrictions are now cleared.  Starting in January,  Adelaide Street from Bay Street to Victoria Street will be reduced to one shared lane for crews to begin replacing the watermain.


In September 2022, the City of Toronto and Toronto Transit Commission (TTC) started work on a series infrastructure upgrades on Adelaide Street. The work involves:

  • 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 works are 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 Church Street.

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.

The City held a virtual Public Information Event on Thursday, July 21, 2022 to provide details on the planned construction on Adelaide Street, and an opportunity for the public to ask questions.
