This page lists notable 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. On average, there are close to 80 confirmed and many more unconfirmed tornadoes that touch down in Canada each year, the vast majority are rated between F0 to F2 in damage intensity level and usually result cause minor structural damage to barns, wood fences, down small power lines and uproot or snap tree limbs. They still pose a danger to the public. Of the provinces, Ontario, Alberta, Manitoba and Saskatchewan average the most tornadoes or close to 15 per season followed by Quebec with less than 10. All other province and territories have significantly less threat from Tornadoes. The peak season in Canada is in the summer months when clashing airmasses move north, as opposed to the spring season in the US southern-central plains, although tornadoes in Canada have occurred in spring, fall and in the most rarest of cases, winter. The Fujita scale was invented in 1971 by Ted Fujita of Chicago, Illinois. It was renamed the Enhanced Fujita Scale on February 1, 2007.
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 use of digital recording devices by citizens. Tornadoes in Canada are enough of a threat for a public warning system to be in place, overseen by the national weather agency, Environment Canada.
For a variety of reasons, such as Canada's lower population density and stronger housing construction due to the colder climate, 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. Seven medium to large size Canadian cities were hit by significant strength tornadoes (F3 or higher) during the 20th century which caused large-scale damage and fatalities, in Regina (1912), Windsor twice (1946 and 1974), Sarnia (1953), Sudbury (1970), Woodstock (1979), Barrie (1985), and in Edmonton (1987).
