Powered by NOAA / National Weather ServiceÉcole secondaire publique L'Héritage is a high school in Cornwall, Ontario, part of CÉP de l'Est de l'Ontario Schools. The forecast above uses the school's own coordinates, so it reflects conditions at this campus rather than an average across the wider area.
Closure decisions for École secondaire publique L'Héritage are almost always made at the district level. If CÉP de l'Est de l'Ontario Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the CÉP de l'Est de l'Ontario Schools forecast).
High schools start earliest, so they feel a storm before the rest of the district does — the first buses often roll while roads are still being treated. That earlier start time is one reason a district watching a morning storm may call the day off entirely rather than run a delay.
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 CÉP de l'Est de l'Ontario Schools before acting on it.
