Will Sault Ste. Marie Schools Be Closed Tomorrow?
Sault Ste. Marie sits at the junction of Lakes Superior and Huron — making it one of Canada’s most snow-exposed cities. Lake Superior’s enormous surface area creates intense lake-effect snow events under northwest winds, delivering snowfall that can rapidly accumulate in the Sault. The city averages approximately 300+ cm of snow per year, one of the highest totals for any Canadian city of its size. The Algoma District School Board covers a vast geographic area from the Sault northwest along the Lake Superior shoreline to White River, encompassing remote communities with challenging winter access.

Sault Ste. Marie Snow Day History
Algoma DSB averages approximately 8–13 closure days per year. Lake Superior lake-effect events are the primary driver — when cold air crosses the full expanse of the largest Great Lake, it can deliver extraordinary snowfall rates in the Sault. Combined with remote community routes that can become isolated in major events, the ADSB closure rate is among the highest in Ontario.
