The TTC has announced that streetcar service will be suspended, in part, over the 509 Harbourfront and part of 511 Bathurst at various times between Tuesday, September 3 and January 2025. This will allow the reconstruction and upgrading of the overhead system between Union Station and Exhibition Loop to be fully pantograph-compliant.
Information is posted in three separate items on the TTC site with the first being the most extensive.
The work will be done in three stages:
- Stage 1: September-Early October 2024
- Overhead work will concentrate on the area from Spadina eastward.
- 509 Harbourfront cars will be replaced by buses between Union Station and Exhibition.
- Buses will use the streetcar right-of-way eastbound between Spadina and York, stopping at the curb at other locations, and at all stops westbound.
- At Queens Quay Station, buses will serve the existing surface stops used by other routes.
- At Union Station, buses will drop off on the southeast corner of Front & Bay, and pick up on Bay south of Front.

- Stage 2: Early October to Late November 2024
- Work will shift to the section between Spadina and Bathurst.
- 509 Harbourfront streetcars will operate between Union Station and Spadina.
- 510 Spadina buses will be extended west to Exhibition Place.
- Stage 3: Late November 2024 to January 2025
- Work will move to the section west of Bathurst.
- 509 Harbourfront streetcars will continue to operate between Union Station and Spadina.
- 510 Spadina buses will continue to run to the Exhibition.
- 511 Bathurst streetcars will operate to Union Station instead of to the Exhibition.
In theory, based on the planned end date for work on 510 Spadina, everything should be back to normal just after New Year’s.
