The total number of casualties from the incident has not been released, but hospital officials have claimed that the number is high enough to “overwhelm the city of Edmonton.” Seven people are confirmed dead, but that number could grow higher.

“It is more patients than any of us want to count right now,” the official told CBS News. “It's a disaster. It's a one in every 15-to-25-year disaster."
