King Street West

What we are doing and why

Beginning in November 2026, the City of Toronto and the TTC will undertake major infrastructure improvements along sections of King Street West. This work is necessary to replace aging watermain infrastructure and renew streetcar tracks to maintain reliable transit service and municipal infrastructure.

The City of Toronto will replace the watermain, and both the City and TTC will jointly renew streetcar tracks in the following locations:

• Close Avenue to Dufferin Street: November 2026 to August 2027
• Shaw Street to Bathurst Street: March 2027 to late 2027
• Portland Street to Spadina Avenue: November 2026 to August 2027
• King Street West and York Street intersection: June to August 2027

The City and TTC will coordinate and phase construction activities across the four project areas, with some overlap where appropriate, to minimize impacts on traffic, transit customers, residents and local businesses.

This work will help keep critical transit and municipal infrastructure in a state of good repair and support reliable service for years to come.

Construction schedules are subject to change based on site conditions, weather and operational requirements.

The City of Toronto will provide project updates on the webpages linked above. The TTC will provide construction and service updates on this webpage as more information becomes available.

TTC service impacts

Construction is scheduled to begin in November 2026 and will require temporary changes to TTC service.

Starting Sunday, November 1, 2026, the following service changes are planned*:

• 504/304 King streetcars will be consolidated into one branch operating between Dundas West Station and Broadview Station.
• West of Spadina Avenue, 504/304 King streetcars will divert via Queen Street West between Spadina Avenue and Roncesvalles Avenue.
• 504C/304C King replacement buses will be introduced and will operate between Sunnyside Loop (at Roncesvalles Avenue) and the Distillery District at Front Street East and Cherry Street.
• 503 Kingston Rd buses will be extended west to Dufferin Gate Loop.
• 508 Lake Shore streetcars will be suspended during this time.

Wheel-Trans service will be maintained throughout the construction on King Street West.

*Service plans are accurate as of the date of posting and may change as planning and construction schedules are finalized.

Route diversion maps will be added to this webpage as they become available.
