Nineteen of the 39 injured service members were in critical condition as military officials investigated how the fast-moving fire began.
WAINWRIGHT, ALBERTA — Four Canadian service members were killed and 39 others injured when a fast-moving grass fire swept through a live-fire training exercise at Canadian Forces Base Wainwright, military and provincial officials said.
The fire broke out at about 4 p.m. MDT Saturday, Oct. 17, in the base’s training area while soldiers from the 3rd Battalion, Princess Patricia’s Canadian Light Infantry, were taking part in high-intensity combat training. Strong winds caused the flames to spread rapidly and overtake an administrative area used by the unit. Nineteen of the injured were in critical condition Sunday, according to Alberta health officials.
The Canadian Armed Forces identified the four soldiers killed as Sgt. Morgan Wong, Pvt. Shaun Farrell, Pvt. Aidan Goulding and Pvt. Hayden Lykkemark. Wong was a member of the Loyal Edmonton Regiment serving with the 3rd Battalion, while Farrell, Goulding and Lykkemark were members of the battalion. Their families had been notified before their names were released.
Maj. Gen. Wade Rutland, commander of the 1st Canadian Division, said military officials had been aware of a grass fire in the training area but initially believed it was sufficiently contained for training to continue. A sudden shift in the wind then sent the fire toward soldiers. Rutland said the flames traveled about a kilometer in roughly 30 to 60 seconds, an unusually rapid advance.
About 85 soldiers were participating in the training when the fire spread, according to military officials. The exercise involved live munitions and was part of preparations by the battalion for rapid-response duties and future deployment. Investigators had not determined what first ignited the grass fire, and officials said they would examine the circumstances surrounding both the fire and the decision to continue training.
Military and civilian emergency crews mounted a large response as the fire spread beyond parts of the training area. Alberta officials said 22 ground ambulances and eight air ambulances were involved, while military search-and-rescue technicians parachuted into the area to support the response. Injured personnel were treated in Wainwright and transferred to hospitals in Edmonton, Calgary and Red Deer.
Hospitals activated mass-casualty procedures as patients arrived. Alberta officials said 19 people were in critical condition, eight were stable and 12 were receiving treatment for less serious injuries. The emergency measures were later lifted after patients were accounted for and transported. Alberta Premier Danielle Smith said some of the seriously injured could require weeks or months of specialized medical care.
The fire was driven by unusually strong winds across the region. Officials said winds had generally remained below 50 kilometers per hour earlier in the day before rapidly intensifying, with gusts reaching about 96 kilometers per hour. The blaze crossed established firebreaks and moved beyond the base fence into surrounding rural land, but local officials said no evacuation order was issued and critical infrastructure was protected.
Prime Minister Mark Carney described the deaths as one of the worst peacetime tragedies for the Canadian military on home soil and ordered flags on federal buildings lowered to half-staff. Defence Minister David McGuinty offered condolences to the families, friends and colleagues of those killed and said the government would support the injured and others affected by the fire.
Military officials said there was no indication of terrorism or outside interference. The 3rd Battalion suspended training after the incident, and investigators were expected to examine the fire’s origin, weather conditions, training decisions and whether existing safety procedures should be changed. Officials cautioned that establishing the full sequence of events would take time.
