City workers took to the streets on Monday to start patching thousands of potholes across the GTA.

Peter Noehammer, director of Transportation Services, said the up and down temperatures have been doing a fair bit of damage to roads.

“There’s a lot of stresses on the roads. Not only from traffic but from the environmental conditions,” he explained. “We’ve got extremely cold temperatures contracting the pavement.”

About 40 to 50 pothole crews fanned out across the city on Monday.

“We’ve had crews out all week trying to do pothole repair. Come the first of next week we’ll be ramping up to do more.”

Hector Moreno, manager of road operations with Transportation Services at the City of Toronto said this may only be the start of repairs.

“We expect that there will be a lot more potholes developing over the next couple of weeks given the recent changes in the weather,” he explained.

Moreno said they are encouraging people to call 311 to report any potholes in their area.

CAA says potholes or other highway maintenance issues can also be reported across the province by contacting the regional Ministry of Transportation District Office. Call 1-800-268-4MTO (4686) to be connected with the regional office in your area.

City crews have already repaired about 4,000 potholes so far this season, compared with about 1,500 at this point last season.

About 188,000 potholes were repaired last year at a cost of $3.6 million.
