Who is responsible if I am injured in a poorly maintained parking lot in Ontario?

Responsibility for a poorly maintained or icy parking lot generally falls on whoever controls and maintains that lot under the Occupiers' Liability Act, which could be the property owner, a business operating on the site, or a snow-removal contractor hired specifically to service it, depending on who actually had that responsibility at the relevant time. As with other snow and ice claims, the occupier does not need to guarantee a perfectly ice-free surface at all times, only that it had a reasonable system for monitoring and treating hazardous conditions given the weather.

Where a third-party contractor was hired specifically to plow and salt the lot, that contractor's own conduct, and the terms of its service contract with the property, often become central to determining fault alongside the property occupier's own responsibility. Because parking lot falls frequently involve more than one potentially responsible party, and because some property types can carry short notice requirements depending on ownership, getting the relevant details, photographs, and documentation as soon as possible after a fall matters considerably to how a claim like this can later be pursued.
