List of Canadian tornadoes and tornado outbreaks

This page lists tornadoes and tornado outbreaks which have harshly touched down in Canada since 1792, this is not a complete listing of all events and range from violent to less damaging tornadoes. On average, there are around 80 confirmed and many more unconfirmed tornadoes that touch down in Canada each year, the vast majority are rated as F0 or F1, not regarded as severe and usually cause minor structural damages to barns, wood fences, down small power lines and uproot or snap tree limbs. 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. 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. 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 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. Six medium to large size Canadian cities were hit by significant tornadoes during the 20th century which caused large-scale damage and fatalities, in Regina (1912), Windsor twice (1946 and 1974), Sarnia (1953), Sudbury (1970), Barrie (1985) and in Edmonton (1987).
