Is my street the city’s responsibility?

Almost always yes — municipalities maintain local streets, collector roads, and most arterials inside city limits. The main exceptions are numbered provincial highways passing through town and private roads.

Who maintains the Trans-Canada Highway?

The province each segment runs through (or its maintenance contractor). There is no federal road-maintenance crew; even the Trans-Canada is provincially maintained.

What about potholes in parking lots or on private roads?

The property owner is responsible. Report those to the business or landlord — municipal crews cannot work on private property.

Why does it matter whose road it is?

Two reasons: reports only get action if they reach the right authority, and damage claims must be filed against the correct body — several provinces have notice deadlines as short as 10 days.

Who Is Responsible for Fixing Potholes in Canada?

Every road in Canada has exactly one owner, and that owner is the only one who will ever fix its potholes. Report to the wrong level of government and your report quietly dies. Here is how the responsibility splits.

Municipal roads: most of what you drive

Cities and towns own local streets, collectors, and most arterial roads inside their boundaries. They take reports through 311 lines, web forms, and apps — and this is the level where RoadRot reports apply pressure best, because municipal response times are measurable and comparable city to city.

Provincial highways

Numbered highways — Ontario’s 400-series, BC’s numbered routes, Alberta’s provincial highways, the Trans-Canada everywhere — belong to the province. Several provinces (BC most extensively) contract maintenance to private operators, but the province remains the place to report and the body to claim against. Each provincial transportation ministry runs a road-condition reporting line.

Boundary cases that trip people up

A provincial highway becomes a city street downtown. Many highways transfer to municipal control inside city limits (a "connecting link"). If the road has a local name and traffic lights, it’s usually municipal.
New subdivisions. Until a subdivision is formally assumed by the municipality, its roads may still belong to the developer.
Private roads, lanes, and parking lots. The property owner’s problem — and their liability.
First Nations and federal lands. Roads on reserve and in national parks are maintained by band councils and Parks Canada respectively.

Not sure? Report it anyway

RoadRot maps every report to the municipality it falls in, and public visibility has a way of finding the right desk. If the pothole already damaged your vehicle, identifying the owner matters more — the damage claim guide covers how to file against a city versus a province.
