The obligation runs to whoever occupies the property, owner or tenant, and covers the full width of the sidewalk, not just a path down the middle. It applies to a corner lot's second frontage as much as to a straight lot's single sidewalk, which matters because a corner lot often means twice the shovelling.
For a seller, an uncleared sidewalk in front of a listing does the opposite of what a tidy front yard does in summer: it signals a property that is not being actively cared for. A buyer forms that impression walking up to the door, long before a lawyer ever discusses legal fees of $800 to $1,500 at possession.
It is a small, unglamorous bylaw, but it is one of the easiest things a seller controls completely. Get your hand-reviewed valuation from Joel Dyck.
