Avalanches

An avalanche occurs when a mass of snow releases from a slope and flows downhill. Avalanches are a natural part of the mountainous environment; hundreds of thousands of avalanches occur in Canada every year.

Avalanches are directly tied to terrain, such as a steep slope. Once in motion, avalanches can also run onto flat terrain and even uphill.

Why prepare for avalanches

Avalanches are most frequent in the mountains of British Columbia, Yukon, and Alberta, but avalanche fatalities have also occurred across the country. Inuit and northern communities may experience more frequent and intense avalanches in the future due to climate change. Learn more about recent and historical avalanches in Canada.
