Closure decisions for École publique Hélène-Gravel are almost always made at the district level. If CS public du Grand Nord de l'Ontario Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the CS public du Grand Nord de l'Ontario Schools forecast).
Ontario averages about 150 cm of snow per year. Ontario school boards make independent closure decisions. Northern boards have higher thresholds than southern Ontario. Toronto rarely closes, while Ottawa, Sudbury, and Thunder Bay close more frequently for heavy snow and extreme cold.
We score the live forecast at this location against the factors that drive closure calls: snowfall total and intensity, when the heaviest accumulation lands relative to the morning commute, ice and freezing rain, wind chill, and how confident the forecast models are. You get a probability for a full closure, a two-hour delay, and an early dismissal.
This is an independent forecast, not an official announcement. Confirm any closure with CS public du Grand Nord de l'Ontario Schools before acting on it.
