The Regina Cyclone, or Regina tornado of 1912, was a tornado that devastated the city of Regina, Saskatchewan, Canada, on Sunday, June 30, 1912. It remains the deadliest tornado in Canadian history with a total of 28 fatalities and about 300 people injured. At about 4:50 p.m., green funnel clouds formed and touched down south of the city, tearing through the residential area between Wascana Lake and Victoria Avenue, and continuing through the downtown business district, rail yards, warehouse district, and northern residential area. Meteorological synopsis The tornado formed south of the city and continued for another north before dissipating. It was approximately wide. The tornado's wind velocity has been estimated at . Occurrence The tornado hit Regina at approximately 5:00 p.m. on June 30, 1912. The tornado formed 18 km south of the city and was roughly 150 metres wide by the time it reached Regina.

"In just twenty minutes it completely leveled a number of houses, and caused other houses to explode as the pressure inside the structures rose when the tornado passed overhead." The affluent residential area to the south was substantially diminished, but the tornado left houses untouched here and there immediately adjacent to houses which were flattened. "[I]n the warehouse district, it destroyed many of the storage buildings. The CPR Roundhouse was stripped to the rafters, and boxcars were pulled from the tracks and hurtled into the air." Such damage was especially appalling to see as well as experience since Regina had been built on an entirely featureless plain, lacking any trees or vegetation other than natural wild prairie grass and without any hills or rivers apart from the tiny spring runoff Wascana Creek, which only flowed in early spring. "The cyclone claimed twenty-eight lives and was the worst in Canadian history in terms of deaths. It also rendered 2,500 persons temporarily homeless, and caused over $1,200,000 in property damage. It took the city two years to repair the damage and ten years to pay off its storm debt." Aftermath The city forced those rendered homeless by the disaster to pay for the
