What Carney told Parliament about the Wainwright fire
Addressing the House of Commons in Ottawa on Monday, Carney said soldiers and reserve members were conducting live-fire exercises at the Alberta base while a fire was burning in the training area. A moment of silence was observed in Parliament before his address, and opposition party leaders paid tribute.
“Driven by ferocious winds, the fire jumped nearly a kilometer in less than a minute to where soldiers were gathered,” Carney said, according to Reuters. He added: “This loss touches every corner of the nation.”
Carney said the investigation is being led by the Canadian Forces National Investigation Service, with support from the Royal Canadian Mounted Police, and that 50 investigators are currently on the ground in Alberta. The Department of National Defence has said there is no indication of terrorism, the military confirmed on Sunday.
Why training continued as the Wainwright flames spread
Maj. Gen. Wade Rutland, commander of the 1st Canadian Division, told reporters on Sunday that military officials had been aware of the fire for hours but believed it was sufficiently distant and contained for training to continue. About 85 soldiers from the 3rd Battalion, Princess Patricia’s Canadian Light Infantry, were conducting “high intensity” combat training with live munitions at two locations — one for throwing grenades and another for practicing attacks on simulated enemy positions — when winds suddenly shifted.
Rutland described the event as “uncommon, rapid,” saying he had “certainly never seen anything like it.” Winds of up to 96 km/h fed the blaze, which began around 4 p.m. local time on Saturday. Investigators have not determined what ignited the grass fire, and establishing the cause could take weeks.
The victims of the Wainwright fire and the toll
The military identified the four soldiers who died as Sergeant Morgan Wong and Privates Aidan Goulding, Shaun Farrell, and Hayden Lykkemark. Of the 39 hospitalized, 19 were in critical condition as of Sunday. Alberta Premier Danielle Smith said many of the injured will require “weeks and months” of specialized, intensive medical care.
Conservative opposition leader Pierre Poilievre, who represents Wainwright in Parliament and was visiting the town, said many survivors suffered severe burns. An emergency response involving 22 ground ambulances and eight aircraft transferred patients to four hospitals in Edmonton, Calgary, and Red Deer, according to CBC.
The battalion had been preparing to become a rapid-reaction force and to deploy to Latvia in the spring as part of NATO’s mission bolstering Eastern European allies, Rutland said. Flags on federal buildings across Canada were ordered lowered to half-staff.
