Sentinel / Grandravine Downsview construction: TTC detours, starting May 9



Since Monday, April 28, the City of Toronto has closed

  • Sentinel Road, northbound lanes, between Sheppard Avenue West and Lamberton Boulevard

to accommodate City contractors who are restoring the roadway after earlier water-main construction.

Since late 2024, the contractors have rebuilt Sentinel Road between Sheppard West and Lamberton Boulevard and replaced the water-main between Dovehouse Avenue and Fonthill Place, including the City-owned portion of substandard water services.

The City is also installing raised cycle tracks on both sides of the road, making for a safer and more comfortable cycling environment. Where feasible, the project also improves pedestrian amenities, including wider sidewalks, accessible crossings and raised crosswalks. During the project, the TTC is also upgrading bus stops to integrate with the cycle track and improve safety for bus operators, transit riders and cyclists.

Starting 7 a.m. Friday, May 9, the City expands the work zone to include parts of

  • the intersection of Sentinel with Grandravine Drive.

That day, the TTC further detours buses along this route around the work zone:

  • 106 Sentinel.

Starting Monday, May 12, it also detours buses along this route:

  • 108A Driftwood via Grandravine.
