If you see a pothole on any City roadway or expressway, you can report it online.




Report pothole damage on roads and expressways by submitting a service request to 311. A service request can be submitted via the 311 Toronto mobile app, online at toronto.ca/311 or by calling 311.

Potholes are created when water penetrates the top layer of asphalt through cracks in the road. After 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. Potholes are more frequent in the spring, after the freeze/thaw action following winter.

The total number of potholes repaired could vary year-over-year dependent on winter conditions. If it is freezing all through the winter, fewer potholes are likely to form due to less number of freeze-thaw cycles. But a milder winter will have higher number of freeze-thaw cycles where temperature falls below freezing and then quickly rises above freezing resulting in more potholes in that year.


Repairing potholes is an affordable way to maintain our roads. Our crews routinely monitor road conditions and identify areas that need repairs.

Crews place asphalt and rake it into the pothole. Then they tamp down the asphalt and smooth it out until the road surface is improved. The job takes 15-20 minutes.

During winter months when temperatures are low and pavement is covered with snow/ice, it is extremely difficult to work with hot asphalt because it cools very quickly. Potholes are temporarily patched with cold mix asphalt to make the road safe. More permanent repairs are performed with hot asphalt when warmer conditions prevail.

Road users and business owners can help by reporting potholes when you see them. Crews will repair potholes within four days of it being reported
