Montréal Snow Day Predictor — French and English School Board Closure Forecast
Montréal Snow Day Predictor
Canada's most accurate snow day predictor
Will Montréal Schools Be Closed Tomorrow?
Montréal is Canada’s second-largest city and one of its snowiest — averaging approximately 210 cm of snow per year. Despite this, Montréal has one of the lowest school closure rates of any major Canadian city this snowy, reflecting the city’s world-class snow removal infrastructure (one of the largest urban snow removal fleets in the world) and a cultural expectation that winter is managed rather than surrendered to.
When Montréal does close schools, conditions are typically severe: 30+ cm accumulations, freezing rain on roads, or blizzard conditions that render the city’s extensive but hilly terrain genuinely impassable even with ploughing. Our predictor applies a higher closure threshold for Montréal boards than for Ontario boards with similar snowfall.

Why Montréal Closes Less Often Than You’d Expect
Montréal employs one of the world’s most advanced urban snow removal operations. The city has approximately 3,000 snow removal vehicles and uses a systematic approach: ploughing → collection → removal to dumps. A major storm that delivers 30 cm can have major arterials cleared within 12–18 hours. Combined with Montréal’s extensive metro system (which operates regardless of surface conditions) and a cultural baseline of winter resilience, schools can often remain open under conditions that would close boards in other provinces.
Montréal Snow Day History
Montréal boards typically see 2–4 closure days per year — despite 210 cm annual snowfall. Major events that trigger closures include severe nor’easters (50+ cm events), intense freezing rain storms that coat roads and sidewalks in ice, and multi-day blizzard events with significant wind and blowing snow.
When Do Montréal Boards Announce?
Boards announce by 6:00–7:00 AM via board websites, TVA Nouvelles, Radio-Canada, 98.5 FM (French), and CTV Montréal (English). The provincial government maintains a consolidated closure listing at education.gouv.qc.ca.

Frequently Asked Questions — Montréal Snow Days
Why does Montréal close schools less often than Toronto despite more snow?
Montréal’s snow removal infrastructure is significantly more advanced and better resourced than Toronto’s on a per-road-km basis. Culturally, Montréalais also have a higher winter tolerance. The result is that conditions that would close Toronto schools often leave Montréal schools open. Closures in Montréal typically signal genuinely extreme conditions.
Do French and English boards close at the same time?
Often but not always. CSSDM (French) and EMSB (English) make independent decisions. In extreme events both typically close. In borderline conditions, one sometimes closes while the other remains open.
