The tornado peaked at F4 on the Fujita scale and remained on the ground for an hour, cutting a swath of destruction in length and up to wide in some places. It killed 27 people, and injured more than 300, destroyed more than 300 homes, and caused more than C$332.27 million in property damage at four major disaster sites. The loss of life, injuries and destruction of property made it the worst natural disaster in Alberta's recent history and one of the worst in Canada's history.
