The City of Toronto will conduct another pothole blitz, beginning today and ending on Saturday evening. A similar blitz took place last weekend, with increased crews filling nearly 15,447 potholes across the city.

Recent weather conditions have resulted in an increased number of potholes. Starting today, the City will place road repair crews on extended hours on Thursday and Friday, and will launch a pothole repair blitz on Saturday.

On a typical day, 25 crews are out repairing potholes, but during the blitz, 55 crews will work to fill potholes across the city, including on the Gardiner Expressway and Don Valley Parkway. Motorists are advised to expect minor delays. The public is asked to be courteous to crews and respect work zones by giving crews space while this work is conducted.

Potholes are created when water penetrates the top layer of asphalt through cracks in the road. When the moisture freezes and expands, sections of the pavement are forced up. The weight of vehicles going over this section of road breaks the pavement and the asphalt is forced out. Toronto’s weather forecast is calling for more freezing/thawing conditions, which is expected to lead to more potholes forming in the coming weeks.

The City has a comprehensive road maintenance program and spends approximately $171 million annually on road repairs, rehabilitation and maintenance work, including between $4 and $5 million to fix potholes. Over the past three years, the City has repaired an average of 210,500 potholes annually.

Road users and business owners can help by reporting potholes when they see them.

Potholes can be reported online at, by calling 311, emailing, or by using an Open311 approved mobile app available at

When reporting a pothole, please provide the following details:

  • the location of the pothole, e.g. the nearest cross streets and a street address if possible.
  • the pothole’s exact location on the roadway, e.g. in the eastbound curb lane.
  • the estimated size of the pothole.

While the City usually repairs potholes within four days, when there are large numbers of potholes to be repaired, the repairs are triaged based on size and repairs are prioritized on expressways and arterial roads first.
