Snow and winter rules in Ottawa

Last verified: 28 September 2026.

The Ottawa check after the plow comes through

Do not merge street service with property responsibility. The city can plow the road while an adjacent owner remains responsible for a sidewalk or access route.

Do not forget the flanking sidewalk on a corner property. Municipal rules can attach to all sidewalks bordering the parcel.

The public sidewalk is a municipal route

Ottawa maintains public roads, sidewalks and pathways according to its winter maintenance priorities. Downtown, transit and high-use pedestrian routes receive earlier attention than lower-priority neighbourhood paths. The City's service completion targets after a storm are not an adjacent homeowner's fixed legal sidewalk-clearing deadline. The official property guidance reviewed does not state a universal number of hours for every owner to clear a public sidewalk. Private steps, access walks and exits still need their own safe maintenance; a shop owner should distinguish these from the City's sidewalk. A corner address may touch routes of different priority, so two frontages can look different on the same morning.

Ottawa's property snow page calls the pile across a driveway a windrow and places its removal with the homeowner. It also says not to push snow onto the street, public sidewalk, path, park or right of way. That means a homeowner cannot solve a blocked driveway by putting the ridge where a pedestrian or plow must cross it. At a corner, preserve visibility near the intersection and keep bins back from the sidewalk and roadway. The Use and Care of Roads By-law 2003-498 governs obstruction and use of the public road allowance; it is not a substitute for checking the current winter operations page.

Ottawa's declared winter weather ban

From November 15 to April 1, the City may declare a winter weather parking ban for significant freezing rain or a forecast of at least 7 cm of snow, including a range that reaches that amount. A daytime ban normally runs 10 a.m. to 7 p.m.; a nighttime ban runs 7 p.m. to 7 a.m. Check the specific declaration, because the forecast trigger does not itself mean a ban has been called. Certain residential permit holders may have exemptions in their permitted areas, but temporary no-parking signs for snow removal can still supersede a permit. There are designated alternatives to street parking when a ban is in force.

The City's crews can return to remove high banks after a first plow, especially on dense streets where a narrow travel lane or a blocked bus stop persists. A parked car can interrupt that second pass even if the road initially seemed passable. The City's live notice and the signs at the curb are better evidence for a driver than a forecast screenshot. Likewise, a resident should check the route's reported service level before treating a still-snowy lower-priority sidewalk as an owner violation.

Two distinct enforcement scenarios

A driver leaves a vehicle on a street during a declared ban, believing that a residential permit always exempts it; a temporary signed snow-removal restriction can still lead to a ticket and tow. A different problem arises when a contractor pushes a private parking-lot pile over a newly opened public sidewalk, requiring municipal intervention under road-use rules. These examples illustrate the rules rather than document specific tickets. Ottawa residents should verify the declaration time, permit terms and current signs for the particular block.

A ban notice and a plow target answer different questions

Ottawa may announce a parking ban before snow is on the ground because the forecast meets the declaration threshold. A resident should look for the City's announcement and the 10 a.m. or 7 p.m. start, then check whether a permit exemption applies at that address. A temporary removal sign still controls its block. The next morning, a road may be clear while a residential sidewalk is awaiting a separate machine. The City's priority standard gives an expected service sequence, but it does not create an adjacent-owner hours-after-snowfall offence. Report a missed public sidewalk using the service category and location.

When clearing a driveway, leave the windrow on the lot without covering a hydrant, curb ramp or sightline. A corner property should not treat the side road allowance as a free snow-storage strip. Ottawa's public guidance specifically tells residents to set bins back from a road or sidewalk rather than on top of the snowbank. At a downtown shop, the city may clear the public path while the operator treats its recessed entrance, which may collect meltwater from the sidewalk. If a customer slips on private steps, a municipal route target will not describe that private condition.
