Wainwright fire: 4 soldiers killed, 27 hospitalized, investigations continue One week after a deadly fire at Canadian Forces Base Wainwright, four soldiers are dead and 27 remain hospitalized. Multiple investigations are underway into how the fire started and spread. One week has passed since a deadly fire at Canadian Forces Base Wainwright in Alberta. Officials say four soldiers were killed and dozens more were injured when a fire swept over the base on Oct. 17. On Thursday, officials said 27 injured soldiers remained in various hospitals, with 13 in critical condition. Twelve others have since been released. The dead have been identified as Pte. Shaun Farrell, 23, of Prince Albert, Sask.; Pte. Aidan Goulding, 23, of North Vancouver; Pte. Hayden Lykkemark, 19, of Langley, B.C. ; and Sgt.Morgan Wong, 26, of Edmonton. The Oct. 24 update was published at 3:04 p.m. EDT. The fire started as a result of a training event taking place on the anti-grenade launcher range, Brig. -Gen.Vanessa Hanrahan, head of the military police, told Thursday's press briefing. She said the training was routine. It is not clear exactly how the fire started. Officials said no gas infrastructure was damaged.Officials Rule Out Explosion At Wainwright FireHanrahan told reporters there was no indication that there was an explosion of any kind that resulted in the fire or that an explosion was triggered by the fire. Maj. -Gen. Wade Rutland of the 1st Canadian Division told reporters that, just before 4 p.m. local time, the fire spread to the pairs range, where soldiers train in pairs to provide covering fire.Military officials would not touch on why training continued despite the fire when pressed by reporters Thursday. Hanrahan said it is part of the military police investigation. The investigative team is still out there determining all of the decision-making that happened once the fire started, up to and including when they responded to the incident involving the tragedies, she said.She said it would be inappropriate for her to speculate now about all of those decisions and any of the other aspects of the investigation. Once the investigative team has time to review all the evidence and do what it needs to do, she will be in a better position to provide accurate information, Hanrahan said. On Thursday, Rutland said high winds contributed to the fire's spread.High Winds Helped Spread The Base FireUncommonly high winds took a pre-existing range fire towards the pairs range and it overtook the soldiers' position, he said. The fire crossed the base fire guard and burned beyond the training base. Hanrahan said in her opening remarks that firefighters were unable to suppress the fire because it was in a permanent danger area of the base. Instead, the fire was being monitored, she said.Permanent danger areas can be contaminated with unexploded munitions. Rutland began his part of the briefing by correcting information he had given previously. I said the injured soldiers were conducting a section attack range. This was incorrect, Rutland said.They were setting up for a pairs range. This is where two soldiers attack a target, taking turns covering and firing for one another. In our training sequence, soldiers re-qualify on their weapon individually, then conduct a pairs range, and then move on to the next progression, which is a section attack range. There are several investigations in the works and it is not clear how long they will take.Board Of Inquiry Will Examine Incident DetailsA military-led board of inquiry will look into the broader circumstances and make recommendations. Normally, those investigations are done to illustrate systemic issues for us to take actions on, Chief of the Defence Staff Gen. Jennie Carignan said Thursday. The military says a board of inquiry is a fact-finding investigation to determine how an incident happened and how similar incidents can be prevented in the future.Rutland said previously the overall investigation would take at least a month, but on Thursday he broadened that timeline to account for the inquiry. This underestimated the scope of the upcoming board of inquiry, which will take as long as it takes to examine all facets of the situation, he said. Hanrahan said that inquiry has not been launched but it will be in the near future.Independent Military Police Investigation Is UnderwayHanrahan said the military police investigation is being conducted independently from the Canadian Armed Forces chain of command. Their role is to establish the facts and determine whether any criminal or service offence may have occurred, she told reporters, adding 30 people are working on the investigation. The involvement of the military police should not be interpreted as an indication that an offence has taken place.She said the investigation's findings will be provided to Canadians but did not say how long it will take. The Alberta Chief Medical Examiner's office, which probes fatalities in the province, is also conducting an investigation. No timeline was provided for that investigation either.
