A rapidly spreading fire at a military training base in Alberta has resulted in four fatalities and left dozens injured, officials confirmed. The blaze broke out Sunday evening at Canadian Forces Base (CFB) Wainwright, one of the busiest military training sites in the country.

Alberta Premier Danielle Smith reported that 39 individuals were hospitalized following the incident, with at least 19 in critical condition. The exact cause of the fire remains under investigation, but Maj. Gen. Wade Rutland, commander of the 1st Canadian Division, said the fire originated from a grass area within the training grounds and spread quickly. Authorities have stated there is no indication the fire was related to any terrorist activity.

Prime Minister Mark Carney described the event as “one of the worst tragedies for the forces on Canadian soil in peacetime,” underscoring the severity of the incident and its impact on the Canadian military community.

Emergency responders worked through the night to contain the fire and assist those affected. Details about the identities of the victims and the total number of individuals involved in the training exercise were not immediately released.

CFB Wainwright plays a key role in preparing Canadian military personnel for various operations and trainings. The base’s leadership has pledged full cooperation with investigators to determine the fire’s cause and prevent similar incidents in the future.

The military community and government officials have expressed condolences to the families of the deceased and support for the injured as recovery efforts continue. Further updates are expected as the investigation progresses.
