When snow will be cleared
Crews first work on treating or clearing major roads, on-street bike lanes, priority sidewalks, pedestrian crossings, bus stops and specific trails. Then crews focus on clearing residential roads and secondary streets.
The amount of time it takes to treat and clear roads and sidewalks depends on the amount of snow that’s fallen.
The City plows when five centimetres of snow or more accumulates. If there is less than five centimetres of snow, roads, sidewalks, bus stops and trails are salted, but not plowed.
|Type of road||Less than 5 cm of snow||5 to 15 cm of snow||15 to 30 cm of snow||More than 30 cm of snow or back-to-back storms|
|Major and priority roads, priority sidewalks, bus stops, pedestrian crossings, specific trails||Salted within 12 hours after the end of a snow fall||Plowed and salted within 12 hours after the end of a snow fall||Plowed and salted within 24 hours after the end of a snow fall||Plowed and salted more than 24 hours after the end of a snowfall|
|Residential and secondary roads||Salted within 24 hours after the end of a snow fall||Plowed and salted within 24 hours after the end of a snow fall||Plowed and salted within 36 hours after the end of a snow fall||Plowed and salted more than 36 hours after the end of a snowfall|
If the snow starts and then stops again, these timings will reset. Plows won’t be out until the snow has stopped completely.
Significant weather events
In extreme weather conditions, the City may declare a significant weather event. During a significant weather event, the timing for winter maintenance crews to clear the snow resets when the event is over.
Priority roads are routes for emergency vehicles, public transportation and most street traffic. Certain residential roads are also considered priority roads, depending on their geography.
The Region of Peel clears snow on regional roads:
- Airport Road
- Britannia Road West/Hurontario Street to west City limit
- Derry Road East and West
- Dixie Road
- Erin Mills Parkway/North Sheridan Way to Mississauga Road/Turner Valley Road
- Mississauga Road/Turner Valley Road to northern limit of the City
Priority sidewalks are located on major roads or bus routes, or outside of hospitals, schools or long-term care homes.
Track snow plows
Find out where snow plows are by using the snow plow tracker.
You can also use the Mississauga Roads app to track the location of plows.
Winter salt and the environment
The City uses rock salt, or sodium chloride, to clear main roads, residential streets, sidewalks and bus stops. If there’s a major storm coming, the City may use brine to pre-treat priority roads a few days ahead of time. Brine is water saturated with salt. Spraying it on the roads makes it harder for ice to form, making the roads easier to plow.
If the temperature drops below -7° Celsius, we use treated salt, or magnesium chloride on residential, non-priority roads. Treated salt works better at colder temperatures, which means we can use less salt, and there’s less of an impact on the environment.
If your street has not been salted or plowed within these timelines, please contact 311 (905-615-4311 outside City limits).
