King Street West and Dufferin Street

Planned work

As of September 29 until mid-November 2025, the City of Toronto and TTC are renewing aging streetcar tracks at the intersection of King Street West and Dufferin Street. The construction is expected to take approximately six weeks and requires a full closure of the intersection and diversions to local streetcar and bus routes. See below for more information about the ongoing streetcar and bus diversions in the area.

Once the streetcar track work is completed, the City of Toronto will replace the sidewalks and install tactile plates at the intersection. Learn more about City's work here.

Timing

The streetcar track renewal at the King Street West and Dufferin Street intersection was originally scheduled for 2024, as part of broader track and watermain replacement work between Dufferin Street and Shaw Street. However, due to supply chain challenges, the project was deferred to fall 2025.

Travel and parking impacts

• The King Street West and Dufferin Street intersection is closed to through traffic due to ongoing construction.
• Parking is not permitted within the fenced work zone.

Work hours and noise

• Excavation and removal of old tracks will occur at various times throughout the day.
• Concrete milling and breaking will primarily take place between 7:00 a.m. and 11:00 p.m.
• TTC crews will work 24/7 during rail installation to ensure the integrity of the new tracks and concrete.
• Overnight work and noise should be expected.

***NOTE: Timing and diversion details are subject to change.

Wheel-Trans and Community bus service 

• The 402 Parkdale Community bus continues to operate on its regular route during construction
• Wheel-Trans services remains accessible in all areas where local traffic is permitted.

Keeping transit moving during construction

In July 2025, City Council approved temporary transit priority measures (TPMs) to support diverted streetcar and bus service during construction.

Key TPMs include:

• Extending existing "No Stopping" prohibitions along Queen Street West (Shaw Street to Roncesvalles Avenue) and Shaw Street (King Street West to Queen Street West).
• Installing turning restrictions at the King & Shaw and Queen & Shaw intersections.
• Supporting the 29 Dufferin bus diversion with additional "No Stopping" prohibitions on certain streets in Liberty Village to facilitate bus turns and end-of-line operations.

These measures aim to improve service speed and reliability for an estimated 91,000 daily streetcar riders and 42,000 bus riders.

City crews have updated parking and traffic signage. Once construction wraps up in mid-November 2025, parking will be restored and turn restriction signage removed.
