Report a pothole in Québec

Why Québec gets potholes

Québec City sits in one of Canada's roughest road-climate zones. The ground freezes to a depth of 1.2 to 3 metres for more than four months of the year, and when the spring thaw arrives, pavement reactions under load are 50 to 70 percent more pronounced than what's recorded in summer. De-icing salts accelerate the damage on top of that. A 2021 CAA-Québec report put the cost of poor road conditions at $258 per driver annually in vehicle repairs, more than double the national average.

How to report potholes in Québec

To report a pothole or file a vehicle damage claim in Québec City, call 311 or use the online form on the City of Québec's website. For potholes on provincial highways and autoroutes (the A-40, A-73, A-440, and similar numbered routes), the responsible authority is the Ministère des Transports du Québec (MTQ), not the city. RoadRot works alongside those channels: you drop a pin on the public map, rate the severity, and other drivers can confirm your report to build a visible record. If you want to push harder, the built-in email-your-rep tool helps you send a complaint directly to your municipal or provincial representative about a specific pothole.

Common questions

Who is responsible for fixing potholes in Québec City?

It depends on the road. Local and municipal streets fall under Ville de Québec. Provincial highways and autoroutes passing through the city, like the A-40 or A-440, are the responsibility of the Ministère des Transports du Québec (MTQ). If you're not sure which authority covers a specific road, starting with 311 is a reasonable first call.

Does Québec City have a 311 service for pothole reports?

Yes. You can call 311 or fill out a form on the City of Québec's website to report a pothole or submit a vehicle damage claim. Damage claims in particular have surged in recent years, so documenting your report clearly with dates and photos helps.

How do I claim compensation for car damage caused by a pothole in Québec?

File a damage claim with the City of Québec through 311 or the city's online form. Keep receipts for any repairs, note the exact location and date of the incident, and photograph the pothole if you can. The city received 469 damage claims from drivers in 2025, more than triple the 127 filed in 2024, so the process is well-established even if approval isn't guaranteed.

When is pothole season at its worst in Québec?

Spring is the worst period, typically late March through May. The deep freeze that builds up over winter thaws unevenly, and the pavement absorbs and expels water in ways that tear it apart from underneath. Research by the Ministère has shown that pavement under load is 50 to 70 percent more vulnerable during this thaw period than it is in summer.

What does RoadRot actually do with pothole reports in Québec?

RoadRot puts your report on a public map where other drivers can see it and confirm it. It doesn't forward anything to the city or contact 311 on your behalf. What it does offer is visibility and a built-in tool to email your municipal or provincial representative directly about a specific pothole, which you trigger yourself.
