St Clair Avenue West
As part of TTC’s plans to maintain state of good repair and continue to modernize the system, staff have completed streetcar overhead power upgrades for the 512 St Clair streetcar and infrastructure upgrades on the through-tracks at St Clair West Station.
TTC coordinated our projects with multiple third-party works (Metrolinx, City of Toronto, and Toronto Water) planned in this area to minimize the overall duration. Future upgrades at the St Clair Station loop are planned for 2025.
The 512 St Clair Streetcar has been replaced by buses to permit critical overhead power upgrades. 512 St Clair streetcars will resume between Gunns' Loop and St Clair Station beginning June 23, 2024 and bus replacement service will be suspended.
Please note that work remains inside the St Clair West Station loop until the end of 2024. Starting June 23rd, customers will temporarily board outside St Clair West Station – at the closest stops at Bathurst and at Tweedsmuir, while TTC completes structural and track upgrades in the St Clair West Station loop.

Construction Update – Spring 2024
The TTC is coordinating infrastructure upgrades with multiple third-party works (Metrolinx, City of Toronto, and Toronto Water) along the corridor to reduce the overall duration that buses need to operate in place of streetcars.

- Upgraded escalators at the south entrance of St Clair West Station.
- Toronto Water has completed sewer rehabilitation work along St Clair Ave West within the TTC streetcar right of way.
- City of Toronto Caledonia bridge rehabilitation work.
In progress
- St Clair West Station Loop – full track renewal

Frequently Asked Questions
Why can’t buses use the dedicated streetcar lanes?
The TTC completed an operational test to examine whether buses could safely operate within the streetcar right of way during construction. The test showed that the narrow lane width, overhead poles, and raised curb heights do not permit safe bus service. Work is currently underway to permit bus operations in select segments with no centre poles, where feasible to do so, including with required traffic signal modifications.
When will streetcar service resume in the area?
Based on the progress of work to date, TTC is on schedule to return 512 St Clair streetcar service this summer as planned.
What is TTC doing to facilitate faster and more reliable bus service?
To help facilitate better flow of transit and all vehicular traffic on St Clair Ave West during construction, the below measures are being implemented:
- 30 metre “no standing zones” installed at all 512 St Clair bus stop locations. This facilitates intended pick-up in curb lanes while traffic continues past.
- TTC is staging construction at St Clair West Station to complete the east-west track renewal first. This will be done to return streetcar service between St Clair West Station and Lansdowne as soon as possible.
- Council Council passed a Motion to extend rush hour parking restrictions on segments of St. Clair Avenue West. On-street signage has been adjusted by the City to match approved by-law changes.
The escalator on the South Side entrance to St. Clair West Station is out of service; when can we expect it to be in service?
The escalators are now upgraded. For the most up to date news, please refer to the accessibility page at Accessibility (ttc.ca).
How much notice was provided for this project?
In May 2023, project communications were posted online and communicated to area councillors and BIA (Business Improvement Areas). For a full list of communications, please see slides 4 and 5 of the presentation here: St Clair Infrastructure Improvements (ttc.ca).
