Canadian Prime Minister Mark Carney announced Sunday that four service members were killed and dozens more seriously injured after a fire broke out during military training at a base in Alberta, calling it one of the country’s worst peacetime military tragedies on domestic soil.
The deadly fire erupted Saturday at Canadian Forces Base Wainwright, where fierce winds fueled flames that spread beyond the installation and into surrounding rural areas. Canadian military officials said there were no indications of terrorism, though the cause remained under investigation.
Carney said in a televised address that the families of the four service members killed had been notified and that the situation was still evolving.

Canadian Defense Minister David McGuinty initially confirmed fatalities and injuries but did not provide a casualty count, Digital previously reported.
“I cannot recall such an incident in my short time for sure as a minister, but I cannot recall an incident like this in recent memory,” McGuinty told reporters.
The exact number of injured service members remained unclear Sunday, with victims receiving treatment at hospitals in Wainwright, Edmonton, Red Deer and Calgary.
Several hospitals across Alberta activated a “Code Orange,” an emergency designation for mass-casualty incidents, as medical personnel scrambled to treat the wounded.

“This number of patients would overwhelm the city of Edmonton,” Dr. Warren Thirsk, an emergency department physician at Royal Alexandra Hospital, told CBC News. “It is more patients than any of us want to count right now. It’s a disaster.”
