Four Canadian soldiers killed as a wind-driven grass fire overran live-fire training at CFB Wainwright

Four members of the Canadian Armed Forces died and 39 were injured when a fire swept through a training area at Canadian Forces Base Wainwright in Alberta on Saturday afternoon, October 17, according to National Defence. The Associated Press and BBC report that 19 of the injured were in critical condition.

What's confirmed

In a release dated October 18, National Defence said the incident happened at about 4 p.m. Mountain time. Soldiers from 3rd Battalion, Princess Patricia's Canadian Light Infantry, part of 1 Canadian Mechanized Brigade Group, were conducting live-fire training under Exercise APOLLO SHOOTER. A fire started during that training, and high winds pushed it rapidly across the unit's administrative area, the department said.

The department named the four who died: Sergeant Morgan Wong of the Loyal Edmonton Regiment, serving with 3rd Battalion, and Privates Shaun Farrell, Aidan Goulding and Hayden Lykkemark of 3rd Battalion. Defence Minister David McGuinty and Chief of the Defence Staff Gen. Jennie Carignan issued condolences.

What officials have said about how it happened

Maj. Gen. Wade Rutland, who commands 1st Canadian Division, told reporters that commanders had known about a grass fire for hours and believed it was contained well enough for training to go on, AP reported. CBC News reported the same account: Rutland said range control knew about the fire for several hours, but it was decided that training "could carry on for a certain amount of time." Then the wind turned. Rutland said the flames covered about a kilometre in well under a minute, which he called abnormal, according to the BBC.

CBC News, citing weather data, reported that winds gusted and changed direction around 4 p.m. that day, when Environment Canada had a wind warning in place for central and southern Alberta (CBC).

Early local reports suggested a gas line had been struck. The military later said investigators don't believe oil or gas infrastructure caused any explosions, and that there is no sign of terrorism, the BBC reported. The cause of the fire itself has not been made public.

How has the military responded?

Prime Minister Mark Carney called it one of the worst peacetime tragedies in the Canadian military's history, according to the BBC. Speaking in the House of Commons on Monday, he said the Canadian Forces National Investigation Service, supported by the RCMP, is leading the investigation, with 50 investigators on site, CBC reported.

Alberta's health service said its emergency response ran about 10 hours and used 22 ambulances and eight aircraft, the BBC reported. Edmonton's Royal Alexandra Hospital declared a mass-casualty code orange on Saturday night and stood it down Sunday.

In an Oct. 22 update, National Defence said 27 members were still in hospital and 12 had been released. About 28 civilian burn-care specialists were flown from Toronto to Edmonton on a military aircraft. The department said military police are investigating independently of the chain of command, to find whether any criminal or service offence occurred, and that a separate Board of Inquiry will be convened.

What don't we know yet?

• What started the fire on the range, and why training continued once it was burning. National Defence had not released a cause as of Oct. 27.
• Whether the death toll will rise. Officials have said many of the injured have severe burns.
• When the military police investigation and the Board of Inquiry will report.

We'll update this story as National Defence releases more.
