Four military personnel were killed and dozens injured in a major fire at CFB Wainwright, a Canadian Forces base southeast of Edmonton, Alberta. The incident occurred during a training exercise on Saturday. Alberta Premier Danielle Smith confirmed 39 patients are being treated in hospital, with at least 19 in critical condition. The cause of the fire remains under investigation.

The fire broke out while soldiers were engaged in a training exercise. Strong winds spread the flames beyond the base. The Alberta government described the fire as “significant and tragic.” Prime Minister Mark Carney called the incident a “serious incident” and expressed support for those affected. Defence Minister David McGuinty did not provide casualty figures or details about the cause.

This is not the first major incident at CFB Wainwright. Past fatalities on Canadian military bases have been recorded, though details of previous events are not specified. The current fire has raised concerns about safety protocols during training exercises. The investigation into the cause is ongoing, with authorities working to determine whether an explosion or other factor contributed to the blaze. The incident has prompted statements of sympathy from provincial and federal leaders.
