Sudden wind shift ignites grass fire during live-ammo drill, killing four soldiers at CFB Wainwright

An internal Canadian Armed Forces memo reveals that a live-ammunition training exercise at CFB Wainwright on Saturday began under low fire-risk conditions, but an abrupt wind shift ignited a grass fire that quickly overran the range. Strong gusts, part of a high-wind warning issued by Environment Canada, drove the fire toward the personnel area, breaching a fire guard and spreading outside the base, prompting the evacuation of a nearby residence.

Four soldiers from C or Charlie Company, Third Battalion of the Princess Patricia’s Canadian Light Infantry, were killed, while 31 suffered serious injuries and several others sustained minor wounds. Fifteen of the wounded were intubated and transported to the University of Alberta and Royal Alexandra hospitals. The fire has been contained but remains smoldering, and investigators from the Canadian Forces National Investigation Service, supported by the RCMP, are on site. Prime Minister Mark Carney declared the incident one of the worst peacetime tragedies in Canada and ordered flags at half-mast on federal buildings.
