King Street West and Dufferin Street

Planned work

Starting as early as September 22 until late October 2025, the City of Toronto and TTC will renew the ageing streetcar tracks at the King Street West and Dufferin Street intersection. The City of Toronto will also undertake sidewalk replacement and tactile plate installation at the intersection. Learn more about this work on the City of Toronto's project webpage

Streetcar track renewal at this intersection was originally planned to take place in mid-2024 as part of the King Street West Watermain and Streetcar Track Renewal project (Dufferin Street to Shaw Street) that year; however, due to supply chain challenges, this work was deferred to 2025.

Expected timelines and travel impacts

Work is expected to start as early as September 22 and continue into late October 2025 for approximately six weeks. During this time, the King Street West and Dufferin Street intersection will be closed to through traffic. Parking will also not be permitted within the fenced work zone.

Work hours and noise

• Excavation and removal of old streetcar tracks will occur at various times throughout the day. Concrete milling and breaking activity will mainly occur between 7:00 a.m. and 11:00 p.m.
• TTC crews will work around the clock (24/7) during the rail installation work phase to preserve the integrity and quality of the newly installed streetcar rail and freshly poured concrete.
• Some overnight work/noise should be expected.

Keeping transit moving during construction

In July 2025, City Council approved temporary transit priority measures (TPMs) aimed at supporting TTC streetcars and buses while they divert around the King Street West and Dufferin Street construction-related intersection closure from late September to late October 2025.

The planned streetcar/bus diversions are expected to significantly increase transit activity on the diversionary sections of Queen Street West and Shaw Street. The proposed TPMs include new and extended "No Stopping" parking zones, as well as turning restrictions. These changes are intended to improve service speed and reliability while reducing delays for an estimated 91,000 daily streetcar riders and 42,000 bus riders.

City staff will begin adjusting the parking and traffic signage on September 18, 2025 and once the streetcar/bus diversions come to an end in late October 2025.
