State of good repair projects and third party works

St Clair Avenue West

As part of TTC’s plans to maintain state of good repair and continue to modernize the system, staff started streetcar overhead power upgrades for the 512 St Clair streetcar on September 3, 2023 and are coordinating infrastructure renewal projects inside St Clair West Station and subsequently St Clair Station.

TTC is coordinating our projects with multiple third-party works (Metrolinx, City of Toronto, and Toronto Water) planned in this area over the next few years to minimize the overall duration.

Effective September 3, 2023, the 512 St Clair Streetcar has been replaced by buses to permit critical overhead power upgrades beginning at Bathurst/St Clair and proceeding westerly. 

An overview of the multiple projects being coordinated can be found below.

  • 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.

    How long do I have to take the bus for?


    Sections of St. Clair Ave West will open up at different times. Please check St Clair Avenue West ( for updates and latest news regarding construction on St. Clair. TTC is prioritizing renewal of east-west tracks through St Clair West Station, and between the station and  Earlscourt Loop (Lansdowne) in order to return service in that section first  - while City construction continues in the long term at the Caledonia Bridge – which precludes running service west of Lansdowne to Gunns Loop.


    Why does bunching of buses occur and why 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” were installed at all 512 St Clair bus stop locations. This will best facilitate intended pick-up in curb lanes while traffic continues past.
    • Café TO curb lane patios were removed in mid-October.
    • TTC and the City will update signals between the pinch points of Vaughan Road to  Bathurst and between Keele and Old Weston Road - specifically to permit bus operations in the right-of-way - where there are no centre poles, and it is safe and feasible to do so. Once overhead power upgrades are installed in these sections, the signal work can proceed.
    • TTC is proposing an extension of rush hour parking prohibitions to assist bus operations- for all of our customers. The final decision on additional parking hour prohibitions will be made by the City of Toronto.
    • 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 – while third party bridge work west of Lansdowne at Caledonia continues.


    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 at the end of their designed life and are undergoing a complete overhaul, meaning that all components are being renewed. The up escalator is now back in service.
