Timmins Snow Day Predictor – DSB Ontario North East and Northeastern Catholic
Will Tomorrow Be a Snow Day?
Canada's most accurate snow day predictor
Timmins is one of Northeastern Ontario’s largest communities, sitting deep in the Canadian Shield where winters are long, cold, and snowy. The city averages approximately 300+ cm of snow per year – roughly double Toronto’s total – and experiences sustained extreme cold from December through March. The District School Board Ontario North East serves Timmins plus a vast, sparsely populated northern territory connected by highways that can become impassable in severe weather, making both snowfall and extreme cold frequent closure triggers.
Will Timmins schools be closed tomorrow? Enter your city in the predictor above for tonight’s closure probability, updated hourly from Environment Canada data. Always confirm with your school board’s official channels before making plans.

Timmins Snow Day Triggers – What Closes Schools Here
Timmins closures are driven by two distinct northern factors:
- Heavy Northern Ontario snowfall: Timmins receives 300+ cm annually. Major snowfall events combined with Canadian Shield terrain and forested, drifting-prone roads regularly close schools.
- Extreme cold: Sustained temperatures below −35°C are common in Timmins winters. When wind chill reaches −40°C or colder, cold-day closures are triggered to protect students waiting at rural bus stops – a pattern more like the Prairies than Southern Ontario.
- Highway conditions: DSB1 buses travel long distances on Highways 101 and 655 to serve outlying communities. When these routes are snow-covered or experiencing whiteout conditions, buses cannot run safely.
- Ice fog and freezing conditions: Extreme cold combined with any moisture can produce ice fog and treacherous road conditions across the region.
How Often Do Timmins Schools Close?
The DSB Ontario North East averages approximately 8–13 closure days per year — among the highest closure rates in Ontario, reflecting both heavy Northern Ontario snowfall and frequent extreme cold events. December through February are peak months.

Frequently Asked Questions – Timmins Snow Days
Which school board and bus portal does the Timmins predictor track?
The predictor simulates decisions for the District School Board Ontario North East (DSBONE) and the Northeastern Catholic District School Board. The official transportation authority it mimics is the Timmins branch of the Nipissing-Parry Sound Transport Service (NPSSTS).
How much snow triggers a high cancellation percentage on the Timmins predictor?
Because Timmins is in Northern Ontario, infrastructure is highly adapted to winter weather. The predictor rarely shows a high percentage for standard snowfall; it usually requires a major storm warning forecasting over 20 cm of rapid snow or severe blowing snow that reduces highway visibility to zero.
Does extreme cold temperature affect the Timmins snow day predictor?
Yes, temperature is a massive factor in Northern Ontario. The predictor’s probability jumps significantly if the wind chill is forecasted to hit -40°C or colder. At this extreme temperature, school bus diesel engines risk freezing up, and it becomes unsafe for students to wait at outdoor bus stops.
If the Timmins predictor shows a 90% chance of a snow day, can I stay home?
No, you must wait for the official confirmation. Timmins road crews are incredibly efficient at clearing roads overnight. Even if the predictor shows a very high percentage the night before, human spotters checking the roads at 4:30 AM might still find them safe enough to clear buses for morning routes.
What time does the Timmins snow day predictor get replaced by official updates?
The predictor is useful for night-before planning, but official, binding decisions are posted online between 6:00 AM and 6:30 AM. Parents look for the final status directly on local news outlets or the school board transport pages before waking up their children.
