About Mississauga Snow Days

Mississauga is located in Ontario and is served by local Ontario school boards serving the Mississauga area, alongside several private and independent schools in the surrounding region. The Mississauga area averages approximately 150 centimetres of snowfall per year, with the peak snow season typically running from December to March.

In Ontario, closures are communicated through board websites, automated phone calls, local news, and radio, with most decisions finalized in the early morning before bus runs begin. Bus cancellations in the Mississauga area are often announced separately from in-person school closures, and parents are encouraged to monitor official channels each winter morning.

Mississauga's location features a Great Lakes climate where lake-effect snow off Lakes Huron, Erie, and Ontario produces heavy localized snowfall, which means winter conditions in and around Mississauga can vary significantly from one year to the next. Freezing rain, heavy snow, blowing snow, and extreme wind chill are all common reasons for closures. Geographically, Mississauga sits near 43.59°N, 79.64°W, which influences how regional storm systems track across the area.

Historically, schools in the Mississauga area close an average of approximately 5 times per winter season due to snow, ice, or extreme cold weather. Use our Snow Day Predictor above to check tomorrow's real-time school closure probability for Mississauga based on live weather forecast data from Open-Meteo.
