Powered by NOAA / National Weather ServiceCommission scolaire Lester-B.-Pearson serves Montréal and the surrounding area in Quebec, covering 50 schools. When winter weather threatens, the closure decision is made district-wide — which is why the forecast above is centred on the district itself rather than any single campus.
Quebec averages about 210 cm of snow per year. Quebec school service centres (CSS) make regional closure decisions. Montreal closes less often than Quebec City and eastern Quebec, where heavier snowfall and ice storms are more common.
We pull the live forecast for the district's own coordinates and score the factors that drive a closure call: snowfall accumulation and its timing relative to the morning bus run, ice and freezing rain, wind chill, and forecast confidence. The result is a probability for a full closure, a two-hour delay, and an early dismissal.
Districts announce closures between roughly 5 AM and 6 AM, working from conditions on the ground rather than the previous evening's forecast. Weather models are most reliable inside 24 hours, so checking after 6 PM the night before gives you the most accurate read.
This is an independent prediction, not an announcement. Always confirm a closure with Commission scolaire Lester-B.-Pearson directly before acting on it.
