List of fatal and violent Canadian tornadoes
This page lists all tornadoes that have occurred in Canada that have documented fatalities, or have a rating of F3/EF3 or higher in intensity.
Canada adopted the Enhanced Fujita scale on April 1, 2013, with the country using the Fujita scale before. Both scales measure how violent tornadoes are, measuring damage done by tornadoes to look at how fast the windspeeds would be inside of a tornado; however the Enhanced Fujita scale takes into consideration the condition of buildings prior to the tornado when assessing damage. Less than 5% of tornadoes that occur in Canada are rated as F3/EF3 or higher.
The only officially rated F5/EF5 tornado in Canada is the 2007 Elie Tornado, however Thomas P. Grazulis of The Tornado Project has unofficially rated the 1920 Alameda-Frobisher Tornado and the 1935 Benson Tornado as F5 (neither having any official intensity ratings due to their age).
The deadliest tornadoes in Canadian history were the 1912 Regina 'Cyclone' (at least 28), 1987 Edmonton 'Black Friday' Tornado (27), and the 1946 Windsor–Tecumseh Tornado (17).
