What we are doing and why

Beginning as early as November 1, 2026, the City of Toronto and TTC will undertake major infrastructure improvements along sections of King Street West. This work includes replacing aging watermain infrastructure and renewing streetcar tracks to help maintain reliable transit service and keep critical municipal infrastructure in a state of good repair.

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, from as early as November 1, 2026, to late 2027
• Portland Street to Spadina Avenue, from as early as mid-November 2026, to late 2027
• Shaw Street to Bathurst Street, from as early as spring 2027 to late 2027
• King Street West and York Street intersection, from June to late 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

To accommodate the phased start of watermain replacement work, TTC will introduce service changes in two stages:

Starting November 1, 2026:

• 504/304 King streetcars will operate as one branch between Broadview Station and Dundas West Station, diverting via Queen Street West between Shaw Street and Roncesvalles Avenue.
• 504C/304C King replacement buses will operate on King Street between the Distillery District (Front Street East and Cherry Street) and Roncesvalles Avenue.
• 503 Kingston Rd buses will extend west to Dufferin Gate Loop.
• 508 Lake Shore streetcars will be suspended.

Starting as early as mid-November 2026:

• 504/304 King streetcars will continue operating as one branch between Broadview Station and Dundas West Station, with the diversion extended via Queen Street West between Spadina Avenue and Roncesvalles Avenue.
• All other service changes listed above will remain in effect.

Wheel-Trans services will continue to operate in all areas where local traffic is permitted.

Please note: TTC service plans are accurate at the time of posting and may change as construction planning and schedules are finalized.

As construction progresses on King Street West, TTC service will be adjusted to support changing construction activities. Updated service information will be posted on this webpage as it becomes available

Route diversion maps for the affected routes noted above will be available on this webpage and on the respective route pages on ttc.ca.
