About Snow Day Predictor Canada
About Snow Day Predictor Canada
We are the editorial team behind Canada’s most transparent snow day forecast — a multi-model, province-aware predictor built for parents, teachers, students, and bus drivers who need a clear answer the night before a winter storm.
Our mission
Canadian winters are not American winters. A 10 cm overnight snowfall that closes Vancouver and Surrey is a routine Tuesday in Edmonton, and a −40 °C wind chill that shuts Winnipeg schools would never be issued on coastal British Columbia. Until recently, the only snow day predictors available to Canadian families were US-built tools that ignored Environment Canada warnings, the GEM weather model, and the specific closure criteria of provincial school boards.
Our mission is to fix that. Snow Day Predictor Canada exists to give Canadian parents, classroom teachers, high-school students, and school bus drivers a forecast that reflects how their local board actually makes the morning call — not a generic “chance of snow.” We publish our methodology, we cite every data source, and we keep the tool completely free.
How we make every prediction
Every probability we publish starts with a multi-model forecast: the Open-Meteo international ensemble (ECMWF, NOAA GFS, DWD ICON), the Canadian Meteorological Centre’s GEM model, and a WeatherAPI cross-check for the same coordinates. Models disagree often enough that a single source is not safe to rely on — so we query all three in parallel and reconcile them before the engine runs.
The engine itself weighs five closure factors: overnight snowfall accumulation, blowing snow and wind, freezing rain and ice pellets, wind chill, and any active Environment Canada warnings. Each factor is scored against a per-province tolerance threshold, then split into two outputs — a school closure probability and a separate bus cancellation probability, because in the Canadian system buses cancel substantially more often than buildings close. We forecast for the exact 5:30 to 6:30 am decision window superintendents actually use. Full details live on our methodology page.
Why we are Canada-only
We deliberately limit coverage to Canada. Regional differences here are too dramatic to blur into a North American average: coastal BC districts close at 8 cm while Alberta operates through 25 cm, Quebec service centres cancel quickly for freezing rain along the St. Lawrence, and Prairie boards use wind chill thresholds that simply do not exist in the southern United States.
Going Canada-only means Environment and Climate Change Canada warnings, the GEM model, Canadian school board policies, and Forward Sortation Area postal-code geocoding are first-class inputs rather than afterthoughts. Type any postal code — M5H 2N2, V6B 4N7, H2X 3Y4 — and we route the forecast through the closure profile of the actual school board that serves that neighbourhood.
Our editorial team
The Snow Day Predictor Canada editorial team tracks Environment Canada warnings, provincial school board policies, and live multi-model weather forecasts to publish the most transparent snow day probability tool available in Canada. We document our methodology, cite every data source, and update province thresholds whenever school boards revise their closure criteria.
Our editorial standards are straightforward: we cite every data source on the page where we use it, we revise province closure thresholds whenever a school board publishes a policy change, and we never publish sponsored content masquerading as forecast or analysis. If a paragraph reads like a forecast, it is a forecast — and the inputs behind it are auditable.
Editorial independence and honesty
Snow Day Predictor Canada is not affiliated with any school board, student transportation consortium, weather provider, or government agency. We are an editorial product — a research and convenience tool — not an official source of closure information.
For the official decision on whether your child’s school is open tomorrow, always check with your local school board, your transportation consortium, or your provincial education ministry. Our forecast is meant to give you a transparent, well-reasoned probability the night before; the final call belongs to the superintendents who make it between 5:30 and 6:30 am.
