The Northern Tornadoes Project aims to gather information on all the tornadoes occurring in Canada every year. Western University's Severe Storm Survey Team, in collaboration with Environment and Climate Change Canada, conducts damage surveys of recent wind storms.

Approximately 60 tornadoes are identified and verified in Canada each year. Statistical modelling by Environment and Climate Change Canada using tornado, lightning, and population data suggests the actual number is almost four times that number, closer to 230 per year.

Risk associated with tornado events depends on a number of factors including frequency and severity. The Northern Tornadoes Project is working to compile a detailed database of unreported tornadoes to better assess and identify associated risk as well as understand the links to global climate change. Data collection includes high-resolution aerial surveys, satellite imagery, drone surveys and on-the-ground observation.
