This is a list of notable tornadoes, tornado outbreaks, and tornado outbreak sequences that have occurred in Canada in the 21st century. (2001 through 2100). Due to increasing detection, particularly in the US and southern Canada, numbers of counted tornadoes have increased markedly in recent decades although number of actual tornadoes and counted significant tornadoes has not. In older events, the number of tornadoes officially counted is likely underestimated.
On average, there are around 80 confirmed and unconfirmed tornadoes that touch down in Canada each year, with most occurring in Southern Ontario, the southern Canadian Prairies and southern Quebec. Canada ranks as the second country in the world with the most tornadoes per year, after the US. The most common types are F0 to F2 in damage intensity level and usually result in minor structural damage to barns, wood fences, roof shingles, chimneys, uprooted or snapped tree limbs and downed power lines. Fewer than 5% of tornadoes in Canada are rated F3 or higher in intensity, where wind speeds are in excess of 225 km/h (140 mph). Prior to April 1, 2013, Canada used a slightly modified Fujita scale, and as of that date the Enhanced Fujita scale, again slightly modified, was put into use to rate tornado intensity, based on the damage to buildings and vegetation.
Ontario, Alberta, Manitoba and Saskatchewan all average 15 tornadoes per season, followed by Quebec with fewer than 10. New Brunswick and the British Columbia Interior are also recognized tornado zones. All other provinces and territories have significantly less threat from tornadoes. The peak season in Canada is in the summer months when clashing air masses move north, as opposed to the spring season in the United States southern-central plains, although tornadoes in Canada have occurred in spring, fall and very rarely winter.
The reported increase in numbers of tornadoes in recent years may reflect more reporting by citizens and media involvement rather than an actual increase in tornado occurrence (although some natural increase has not been ruled out), in addition to better detection technology i.e. Dopplerweather 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 (EC).
For a variety of reasons, such as Canada's lower population density and generally 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. Urban centres are not immune from the threat of severe tornadoes. Nine medium to large size Canadian cities have been hit by significant strength tornadoes (F3 or higher), which caused large-scale damage and fatalities: Regina (1912); Windsor (1946 and 1974); Sarnia (1953); Sudbury (1970); Woodstock (1979); London (1984); Barrie (1985); Edmonton (1987); Goderich (2011); and Ottawa-Gatineau (2018).
July 1 – an F1 tornado was confirmed near Lac Saint-Jean, Quebec. It tore the roof from a house and knocked out power to several communities.
July 4 – four tornadoes touched down in Southern Ontario causing minor damage. Three were given an F0 rating, and were confirmed near the towns of Argyle, Campbellville and Ayr. The fourth was rated as an F1 and touched down in the Fenelon Falls area knocking over a silo. Two other tornadoes were reported, but not confirmed, near the towns of Arthur and Bancroft. No injuries were reported.
June 11 – Laval, Quebec was struck by an F1 tornado that damaged trees, and many warehouses in the industrial park just north of Autoroute 440. It also caused some vehicles to go off the road as it crossed west to east both lanes of Autoroute 15 during rush hour.
July 2 – a tornado touches down on an area of Narrow Hills Provincial Park northwest of Nipawin, Saskatchewan. It destroyed several residential trailers, turned over a tractor-trailer unit, and caused a number of injuries; the storm also dropped baseball-sized hail that is typical of tornado-producing thunderstorms in the Prairies.
August 10 – two F1 tornadoes occurred near the Ottawa, Ontario region. The first near Burnstown, 10 km (6.2 mi) southeast of Renfrew. It ripped the roof off a barn, snapped several trees and destroyed a shed. The second tornado happened near Thurso.
August 19 – Southern Ontario tornado outbreak of 2005. These associated storms caused extensive widespread damage in a path from Stratford (20 km (12 mi) west of Kitchener), to Peterborough, and along Georgian Bay near Collingwood. A storm cell just to the north of Fergus spawned two F2 strength tornadoes that were particularly damaging, tearing apart trees, farms and overturning automobiles driving on a highway. 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 140 mm (5.5 in) 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 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.
July 14 – a tornado touches down near Gretna, Manitoba, flattening crops, damaging equipment sheds, and tore up trees and power lines.

July 17 – an F1, or possibly a weak F2, hit a La Baie du Diable campground in Ferme-Neuve, Quebec moving RVs and breaking trees.
July 25 – an F0 tornado destroyed a barn in Lac Saint-Jean, Quebec. The same storm produced hail that reached 5–6 cm (2.0–2.4 in) in diameter and caused $2 million damage in the agricultural community.
August 2 – a number of homes and cottages damaged or completely destroyed by a tornado in Combermere, Ontario located in the upper Ottawa Valley. The same storm system spawned an outbreak of fourteen confirmed tornadoes mostly concentrated north of Peterborough in the Haliburton, Kawartha and Madawaska areas, which damaged cottages in the area, some severely. It was the most tornadoes confirmed in Ontario in a single 24-hour span day since 1985 and matched the annual provincial average.

A tornado swept along a corridor of 20–50 m (66–164 ft) wide and 3 to 5 km (1.9 to 3.1 mi) long extending from Pokemouche through Evangeline. The tornado estimated in the lower F1 range (wind estimated around 120 km/h (75 mph)) caused structural damage to a few properties and uprooted/snapped a few trees along the corridor. The sighting of the actual funnel cloud / tornado was reported by a few members of the public. Ended at 47°42′N64°51′W / 47.7°N 64.85°W / 47.7; -64.85
May 15 – An F1 tornado struck the Mitchell, Ontario area around 60 km (37 mi) northeast of London, causing minor damage. It was the third significant tornado to hit the Mitchell area in a three-year span. The same storm system that caused this tornado also produced two other tornadoes (an F0 and an F1) in The Thumb area of Michigan, northern Indiana, and Ohio before crossing Lake Huron into Ontario.
June 22–23 – A rare combination of weather systems converged. on a June weekend causing severe thunderstorms which spawned at least eight tornadoes across southeast Saskatchewan and southern Manitoba. The most significant, and the first confirmed F5 tornado in Canada which touched down near Elie destroying four homes, flipping one home-owner's Chrysler Fifth Avenue onto a neighbour's roof, and heavily damaging a flour mill. 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. A large F3 wedge tornado also touched down near Pipestone and Baldur. Two tornadoes at Lampman and Carnduff, Saskatchewan reported property damage and one injury, Surprisingly there were a minimal amount of reported injuries resulting from all of the tornadoes.
