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).

The first tornado tracked through Milverton to Conestogo Lake (west of Elmira). The second moved from Salem to Lake Bellwood (north of Guelph). The same storm cell later triggered a tornado warning in Toronto and caused extensive flooding with over 140mm (7") of rain in some northern sections of the city, washing out many roads as well as damaging infrastructure such as storm sewers and electrical systems. An unusual tornado possibly touched down within the Toronto, Ontario city limits, although never officially confirmed by Environment Canada. In its wake, the storm left a trail of damage that, according to the Insurance Bureau of Canada, represented the highest insured loss in the province's history, exceeding $500 million. That's more than two and a half times Ontario's losses during the infamous ice storm of 1998 and the second largest loss event in Canadian history.

It was the most tornadoes confirmed in Ontario in a single 24-hour span day since 1985 and matched the annual provincial average.

  • June 22 - June 23, 2007. Eastern Prairie Outbreak. A rare combination of weather systems converged on a June weekend causing severe thunderstorms which spawned at least 8 tornadoes across Southeast Saskatchewan and Southern Manitoba. The most significant, and the first confirmed F5 tornado in Canada was an F5 which touched down near Elie, Manitoba [10] destroying 4 homes, flipping one home-owner's Chrysler Fifth Avenue onto a neighbour's roof, and heavily damaging a flour mill. Because the tornado crossed directly over one of the most travelled portions of the Trans-Canada Highway, a large number of photos and videos were taken [11]. The F5 Elie tornado was described "as bad as they ever get here in Canada" by meteorologist Dave Carlsen of Environment Canada, while he told Canwest Global affiliate CKND-TV [1][12][13]. A large F3 wedge tornado also touched down near Pipestone, Manitoba and Baldur, Manitoba[14]. Surprisingly there were a minimal amount of reported injuries resulting from all of the tornadoes. There were also sightings of 3 small tornadoes becoming one[15]. One of the tornadoes in this outbreak also traveled 15 km (9 miles) south of Baldur, Manitoba and was rated an F3 on the Fujita scale.

Debris reported 1.5 km away (nearly a mile), 50 kg drums moved. Another tornado is sighted in the area but unconfirmed touchdown.[19]
  • July 23, Leduc County, Alberta. A tornado formed over Edmonton International Airport just before sundown amid severe thunderstorms in the Edmonton area as a result of the jet stream depositing cold air into the region's hot, 40 degree Celsius (104 degrees Fahrenheit) weather. The tornado touched just south of the Highway 2/2A junction, scattering rock, dirt, hay and small debris on 16 km (10 miles) of 2A, involving the towns of Kavanagh and Millet. Despite its large appearance, no major damage or injuries were reported, although power was out for a few hours in the vicinity and lightning ignited a range fire west of the airport.

Despite the weakness of the tornado, some roofs detached from houses, and trees and electricity poles broke, causing electrical shortages in an areas stretching from Britianna Bay in the west to Carlington Heights to the east. The damage path was up to 150m wide before lifting. In Gatineau, Québec, severe damage was reported, including detached roofs from a school in Gatineau sector and a commercial building in Hull sector, as well as many trees and electricity poles falling down, which were more likely the results of a microburst or strong winds alone, as no tornado has been reported by witnesses.[56][57] The same storm system also caused a minor F0 tornado in Downtown Windsor,[58] ripping part of the roof off of the local CUPE union hall, damaging some windows on neighbouring homes, and blowing out the windows on an automobile in the union hall's parking lot. The funnel cloud was first spotted over the western part of Windsor, near the University of Windsor, drifting southeast. Damage is reported to be low, with no injuries or deaths.[59]
