Snow and winter rules in Calgary

Last verified: 28 September 2026.

A practical Calgary winter check

For a corner property, include every bordering sidewalk in the check and then verify whether the parking rule changes during plowing or snow loading.

Multiple street frontages can create multiple sidewalk obligations. Commercial and mixed-use properties may be treated differently from detached homes.

The 24-hour clock and the surface it covers

Calgary's snow and ice guidance points to the Street Bylaw 20M88, section 67. Owners or occupants must clear the sidewalk bordering the property down to the bare surface within 24 hours after snowfall ends. Ice that cannot be removed should be treated so pedestrians have traction. The requirement includes a sidewalk along the side of a corner lot; it is not limited to the front-door frontage. Where a pathway borders a property, the City describes a 1.5-metre clearing width. A landlord and tenant should arrange who actually shovels before a storm, since their private arrangement does not move the public deadline.

Calgary's chinooks make a dry-looking morning deceptive. Meltwater can cross a sidewalk in the afternoon and freeze overnight, and a plow can put loose snow back at a curb crossing after the first shovel. Section 67's standard concerns the usable pedestrian surface, not just a photograph taken immediately after one pass. Keep a route for mobility devices and watch for an icy ridge at the driveway crossing. Do not use the road as snow storage; it creates a second hazard and can return as a compacted windrow.

Who opens the driveway after the plow?

Calgary's snow bylaw page says the City does not clear windrows created by its plows. A property owner is not required to clear a driveway or on-street parking windrow, but may choose to do so for access. This is different from the legal duty to clear an adjacent sidewalk. Road crews try to minimize the pile while pushing snow toward the curb. Do not treat an optional driveway opening as if it were the section 67 sidewalk duty, and do not push the ridge back into a travel lane. A City-created obstruction across the public pedestrian path should be described and reported as a sidewalk issue.

The City's Snow and Ice Control plan prioritizes major roads, transit and emergency routes before neighbourhood streets. A declared snow-route parking ban can restrict parking on marked priority routes for up to 72 hours, with activation and end times published by the City. It is not a blanket assumption that every residential street is banned all winter. Move a vehicle before a declared ban starts and follow any temporary local signs. A parked car can force a plow around it, leaving a narrow uncleared strip that later freezes in place.

How a complaint can become a bill

A typical enforcement sequence is a neighbour reporting an icy corner sidewalk after the 24-hour window; an officer checks the location, and the City may issue notice or take steps to clear and charge the property. Calgary also lists escalating fines for noncompliance. The scenario is illustrative rather than a reported case, but it shows why a corner parcel should log both frontages and why a contractor's missed visit matters. Check the current bylaw and current ban map before contesting a ticket, because the sidewalk clock and the route parking restriction arise from different rules.

Using the 24 hours without missing a second hazard

When snow stops on Tuesday afternoon, the adjacent sidewalk should be cleared by the same time Wednesday, regardless of when a residential road plow is scheduled. A corner household can divide the two walks between helpers, but both remain part of the property's perimeter. If a chinook starts melting an older bank, inspect the slope where runoff crosses the walk; treating ice is different from moving new snow. Calgary asks people to keep catch basins and storm drains free so refreezing water does not create a fresh hazard. Sand provides traction where scraping alone will not expose a safe surface.

For a business fronting a priority road, plan for equipment arriving before a side street is serviced. Do not store a private parking-lot pile at the curb where it narrows a route or blocks a bus stop. A later road plow may create a driveway ridge, but that does not extend the section 67 sidewalk deadline. Calgary says it does not clear driveway windrows; a property owner may open one for access without being under a separate driveway-windrow clearing requirement. A snow-route parking notice is checked separately from the 24-hour sidewalk clock.
