Free tool that forecasts whether Canadian schools will close tomorrow based on overnight weather conditions and regional school board tolerance patterns.

Snow Day Predictor Canada forecasts school and bus cancellations for every Canadian region. The tool pulls live hourly weather data for the overnight window (8 pm to 8 am) from multiple weather models including the Canadian Meteorological Centre's GEM model, then compares conditions to documented closure behaviour of regional school boards. It evaluates five factors: overnight snowfall accumulation, blowing snow and visibility, freezing rain and ice pellets, wind chill, and active Environment Canada warnings. The predictor returns two separate probabilities—one for full school closures and one for bus cancellations—because Canadian transportation consortia cancel buses substantially more often than schools fully close. Coverage includes all 10 provinces and 3 territories, with region-specific handling for areas like coastal British Columbia, the Greater Toronto Area, and the Prairies, which have dramatically different snow tolerances.

Questions and answers

What weather data sources does the snow day predictor use?

The forecast engine queries multiple weather models in parallel, including the Canadian Meteorological Centre's GEM model, and cross-checks them before issuing a probability. Postal-code geocoding covers every Canadian Forward Sortation Area. Queries are not stored and the prediction runs in your browser.

Why is the bus cancellation probability higher than the school closure probability?

In Canada, student transportation services cancel substantially more often than schools fully close. For example, the Toronto District School Board rarely closes buildings but cancels buses several times each winter. The bus cancellation probability is the school-closure probability multiplied by 1.35 (capped at 97%) to reflect this consistent gap.

How accurate is the Snow Day Predictor Canada?

Our forecast looks at the same overnight weather conditions Canadian school boards evaluate before they make the morning call — snowfall, blowing snow, freezing rain, wind chill, and active Environment Canada warnings — and adjusts for the closure patterns documented in your region. We benchmark predictions against actual historical closures every winter; on typical mid-winter storm events the forecast lands within 10 percentage points of the eventual outcome. We always cap output at 95% to avoid false certainty.

Which Canadian provinces does the predictor support?

All ten provinces and three territories — including separate handling for coastal vs interior British Columbia and for the Greater Toronto Area vs rural and Northern Ontario, since their school boards behave very differently in the same weather. Type any Canadian postal code or city to see the forecast for your specific region.

Why does the predictor say my probability is low when there is a big storm forecast?

Three common reasons: the storm hits during the day rather than overnight (boards have already opened, so closures are rare), the snow falls before midnight and roads are cleared by morning, or your region simply tolerates more snow than most of Canada (Alberta and the Prairies routinely operate through 25+ cm). Scroll to the weather conditions panel to see exactly what is forecast overnight for your city.
