This page lists tornadoes and tornado outbreaks which have touched down in Canada since 1792, this is not a complete listing of all events and range from violent to less damaging tornadoes. A tornado is a violent rotating column of air which is in contact with both the surface of the earth and a Cumulonimbus cloud or in rare cases the base of a Cumulus While there is no single agreed upon definition generally more than six Tornadoes in a day in the same region is considered a tornado outbreak.

The Fujita scale ( F-Scale) or Fujita-Pearson scale, is a scale for rating Tornado intensity based on the damage tornadoes inflict on human-built structures The Fujita scale ( F-Scale) or Fujita-Pearson scale, is a scale for rating Tornado intensity based on the damage tornadoes inflict on human-built structures The peak tornado season in Canada is in the summer months, as opposed to the spring season in US.

The reported increase in numbers of tornadoes in recent years may reflect better record keeping rather than an actual increase in tornado occurrence (although natural increase has not been ruled out), in addition to better detection technology ie. Doppler weather radar and satellite imagery. A weather radar is a type of Radar used to locate precipitation, calculate its motion estimate its type ( Rain Satellite imagery consists of photographs of Earth or other planets made by means of Artificial satellites. The upswing could also be attributed to other factors, such as improved aerial and ground damage assessment after the fact in sparsely populated areas (particularly the case in remote parts of the Canadian Prairies and Northern Ontario, for example), better trained spotter capabilities and increased population in places like the great plains/Canadian Prairies than in the past. The Canadian Prairies is a region in western Canada, which may correspond to several different definitions natural or political Territorial evolution Those areas which formed part of New France in the pays d'en haut, essentially the watersheds of the Ottawa River, The Great Plains are the broad expanse of Prairie and Steppe which lie east of the Rocky Mountains in the United States and Canada The Canadian Prairies is a region in western Canada, which may correspond to several different definitions natural or political Tornadoes in Canada are enough of a threat to public safety for a public warning system to be in place, overseen by the national weather agency, Environment Canada.

For a variety of reasons, such as sturdier construction for buildings to withstand the harsher winters and Canada's lower population density, Canadian tornadoes have historically caused far fewer fatalities than tornadoes in the United States. The United States of America —commonly referred to as the The deadliest tornado in Canadian history, the Regina Cyclone of June 30, 1912, does not even rank in the top 25 when compared to American tornado fatalities.
