Common questions
Who is responsible for fixing potholes in Montréal?
It depends on the road. Local and borough streets are handled by City of Montréal Public Works, and the city repairs between 120,000 and 200,000 potholes on major streets each year. Autoroutes and numbered highways, like the A-40 or the Décarie, fall under the Ministère des Transports du Québec (MTQ), so complaints about those roads go to the province, not the city.
Does Montréal have a 311 service for pothole complaints?
Yes. You can call 3-1-1, submit a report through montreal.ca, or use the free 311 Montréal app. Between January and late April 2026, the city's 311 service received over 13,000 pothole-related requests, more than three times the volume from the same period in 2024, so response times can vary during peak season.
What's the worst time of year for potholes in Montréal?
Late winter and early spring, roughly February through April, is when conditions peak. That's when temperatures swing above and below freezing most frequently, water works its way into existing cracks, and the freeze-thaw cycle does the most damage overnight. CAA-Québec reported assisting an average of 75 Montréal motorists per day with flat tires during a stretch in early 2026, a 48% increase over the same period the year before.
Can I claim damages for a pothole in Québec?
You can file a damage claim with the City of Montréal if the pothole is on a city-managed street, or with the MTQ if it's on a provincial highway. You'll generally need to document the date, exact location, and evidence of the damage. Having a timestamped RoadRot report or photos from the scene can support your claim, though filing through RoadRot alone isn't the same as filing an official claim with the municipality.
Why do some Montréal neighbourhoods seem to have worse potholes than others?
Geology and infrastructure age both play a role. Montréal sits on a mix of fluvial and glacial terrain, and areas with poor drainage tend to see potholes return season after season. Older neighbourhoods like Rosemont, the Plateau, and Hochelaga have drainage networks that weren't built for today's traffic loads or precipitation patterns, which makes recurring damage more common there.
