King West Construction Plans: 2026-27

Water main construction, coupled with track repairs, will force the diversion of 504 King streetcars from November 2026 to early Summer 2027.

The map below is taken from a report at Toronto & East York Community Council on July 8-9 (p 4).

Two areas will be affected starting November 2026: Close to Dufferin, and Portland to Spadina. At the end of February 2027 work will begin between Shaw and Bathurst Streets.

The following services will operate over the 504 King corridor:

  • 504 streetcar from Broadview Station to Dundas West Station diverting both ways via Queen between Roncesvalles and Spadina
  • 504 bus service from the Distillery District to Sunnyside Loop
  • 503 Kingston Road bus service from Bingham Loop to Dufferin Loop
  • Not shown in the map is the 508 Lake Shore car whose summer 2026 suspension appears to continue through the construction period.

Night service will be provided by:

  • 304 streetcar over the same route as 504 King car
  • 304C bus over the same route as 504C King bus

Projects planned for 2027 includes watermain work and intersection reconstruction at King and York. This was originally expected in Fall 2026, but has been pushed back into the next construction year. TTC advises that King/York is scheduled to start in late June 2027 with the intention of completion before the film festival in September. Other projects will affect King West in 2027, but details for this work have not been announced.

Traffic regulations will be changed at several locations to assist transit vehicle movement during the construction. Details follow the “more” break.
