Landslides
Thousands of landslides occur every year in Canada, but most are small. They occur in all regions but are most damaging in the mountainous regions of British Columbia and Alberta and in the St. Lawrence Lowlands of Quebec and Ontario. Large landslides are less common, occurring only about once every 10 years in Canada.

Landslide facts
- Learn about landslides, research data on landslide activity and browse satellite Earth observational data.
- The speed of a landslide can range from extremely slow to extremely rapid.
- The largest Canadian landslide known occurred in 1894 at Saint-Alban, Quebec. It involved 185 million m3 of material and created a 40 m deep scar that covered an area of 4.62 million m2 (roughly the size of 80 city blocks).
