List of 21st-century Canadian tornadoes and tornado outbreaks
This is a list of notable tornadoes, tornado outbreaks, and tornado outbreak sequences that have occurred in Canada in the 21st century.. 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 the southern Canadian Prairies, Southern Ontario 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. 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. Each year on average, about 43 tornadoes occur across the Canadian Prairies and about 17 occur across Ontario and Quebec. 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 through 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, in addition to better detection technology i.e. 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, 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 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. Ten medium to large size Canadian cities have been hit by significant strength tornadoes, which caused large-scale damage and fatalities: Regina ; Windsor ; Sarnia ; Sudbury ; Woodstock ; London ; Barrie ; Edmonton ; Goderich ; and Ottawa-Gatineau. All figures for damages are in Canadian dollars.
