Thirty-nine other service members were injured, including 19 critically, after high winds drove flames through a live-fire training area.
WAINWRIGHT, Alberta — Four Canadian soldiers were killed and 39 other service members were injured when a rapidly spreading grass fire overtook troops during live-fire combat training at Canadian Forces Base Wainwright, military officials said.
The fire broke out at about 4 p.m. MDT on Oct. 17 while members of the 3rd Battalion, Princess Patricia’s Canadian Light Infantry, were conducting high-intensity training as part of Exercise APOLLO SHOOTER. Canadian military officials said strong winds caused the fire to grow with unusual speed and overtake the unit’s administrative area. Nineteen of the injured service members were reported in critical condition.
The Canadian Armed Forces identified those killed as Sgt. Morgan Wong, who was from the Loyal Edmonton Regiment and serving with the 3rd Battalion, Princess Patricia’s Canadian Light Infantry, and Privates Shaun Farrell, Aidan Goulding and Hayden Lykkemark, all from the 3rd Battalion. The military said 39 members suffered injuries in addition to the four deaths.
Maj. Gen. Wade Rutland, commander of the 1st Canadian Division, said about 85 soldiers were involved in the combat training when the fire advanced. Officials said winds reached about 96 kilometers per hour, or 60 mph, as conditions changed rapidly. Rutland said the flames traveled about one kilometer in roughly 30 to 60 seconds after the wind shifted, leaving personnel little time to respond.
The cause of the fire remained under investigation Monday. Military officials said they had not found evidence of outside interference and did not believe oil and gas infrastructure in the region was responsible. Officials have not publicly established what first ignited the grass fire, and investigators were continuing to examine the circumstances surrounding the training exercise and emergency response.
The scale of the incident triggered a major medical response across Alberta. Twenty-two ground ambulances and eight air ambulances were sent to assist, according to provincial officials. Patients were transported to hospitals in Edmonton, Wainwright, Calgary and Red Deer. Edmonton health facilities activated a code orange, a measure used to coordinate care during a mass-casualty event.
Military and civilian firefighters worked through the night as high winds pushed the blaze beyond the base’s training area and across the installation boundary. The nearby Municipal District of Wainwright said the fire crossed into surrounding rural land, but no evacuation order was issued. Officials later said the fire was being held and was not expected to spread beyond its existing boundaries.
Prime Minister Mark Carney described the incident as one of the worst peacetime tragedies involving Canada’s military on Canadian soil. He ordered flags on federal buildings across the country lowered to half-staff in honor of the four soldiers. Defence Minister David McGuinty and senior military leaders also expressed condolences to the families, colleagues and units affected by the deaths.
CFB Wainwright is one of the Canadian Army’s major training locations and is home to the Canadian Manoeuvre Training Centre and the 3rd Canadian Division Training Centre. The soldiers involved were training in a prairie environment using live munitions. Reuters reported that personnel taking part in the exercise were preparing for deployment to Latvia, where Canada leads a NATO multinational brigade.
The Canadian Armed Forces said its immediate priorities include supporting the injured service members and the families and units affected by the deaths. Military officials are also examining how the fire developed and spread during the exercise. No final cause for the blaze had been announced as of Monday.
