Deaths, injuries after explosion and fire at CFB Wainwright

Updated Oct. 21, 2026, at 9 p.m. MT: Two buses carrying soldiers from CFB Wainwright were greeted by flag-waving supporters along an Alberta highway on Wednesday, days after the deadly fire, The Canadian Press reported in a story carried by CTV News. The story’s headline quotes residents saying “Wainwright stands with you.” We have not been able to confirm further details of the send-off, and officials have not said where the soldiers were headed. The cause has not been determined.

Earlier update, Oct. 21, 2026, at 5 p.m. MT: Alberta Premier Danielle Smith said 27 of the 39 soldiers taken to hospital after the fire are still being treated and 13 of them are in critical condition, CTV News reported on Wednesday. The figure replaces the 33 members the defence minister said were in hospital on Tuesday, and it means 12 of the 39 are no longer being treated in hospital, by our arithmetic of the reported numbers. CBC News and CP24 also carried headlines citing 27 soldiers still receiving treatment. CTV News also reported in its headline that Ontario will send 24 nurses to help Alberta’s efforts; we have not seen further details. The cause has not been determined. Source: CTV News.

Earlier update, Oct. 21, 2026, at 9 a.m. MT: A vigil for the soldiers caught in the fire will be held Wednesday night at the Church of the Nazarene in Wainwright, organized by local faith leaders, The Canadian Press reported. It will be the first chance for residents and base personnel to gather formally and grieve, according to The Canadian Press via CP24. Ryan Wood, pastor of the Church of the Nazarene, said of the military members, “They’re hurting. They’re struggling just like everybody else.” Wainwright Mayor Bruce Pugh said the town is also doing things for its first responders, and that for some the vigil “won’t close the book, but it will help close this chapter in a sense.” CP also reported the ages and home communities of the four soldiers killed, as given in its story: Sgt. Morgan Wong, 26, of Edmonton; Pte. Shaun Farrell, 23, of Prince Albert, Sask.; Pte. Aidan Goulding, 23, of North Vancouver; and Pte. Hayden Lykkemark, 19, of Langley, B.C. Flowers have been left at the Wainwright cenotaph and the Memorial Clock Tower, and flags remain at half-mast. The cause has not been determined, and CP’s story did not report any new casualty figures. Earlier, see our report Military names four soldiers killed in CFB Wainwright fire.

Earlier update, Oct. 20, 2026, at 1 p.m. MT: Defence Minister David McGuinty said 33 Canadian Armed Forces members remain in hospital after the fire, The Canadian Press reported on Tuesday. McGuinty visited the base and members recovering in a local hospital on Monday, CP reported. He said he would not comment on their conditions out of respect for their privacy, called the situation “delicate and evolving” and said the government will provide all necessary support to the injured and their families. The report did not say how many of the 39 injured have been released from care, and the 33 figure is the minister’s, not a separate official count. CP also reported that Carney said 50 investigators are on the ground and that residents paid their respects at a memorial clock tower in Wainwright on Monday. The cause has not been determined.

Earlier update, Oct. 19, 2026, at 6 p.m. MT: Chief of the Defence Staff Gen. Jennie Carignan said it is her “intention” to make public the findings of the board of inquiry into the fire, according to CTV News and CP24. Carignan said two other probes are also under way: a joint investigation by the Canadian Forces National Investigation Service, Alberta’s chief medical examiner and the RCMP, and a separate review led by the Canadian Forces Fire Marshal. She said the fire started far from the training area, behaved unexpectedly and engulfed the area where personnel were, and that many details still need to be confirmed. Carignan said she plans to visit CFB Wainwright before the end of the week, and she praised the military’s response and thanked the surrounding community, CTV News reported. The cause has not been determined. Earlier, see our report Military names four soldiers killed in CFB Wainwright fire.

Earlier update, Oct. 19, 2026, at noon MT: About 50 investigators are working at the scene of the fire, with the Canadian Forces National Investigation Service leading the probe and the RCMP supporting it, Prime Minister Mark Carney told the House of Commons on Monday, according to The Globe and Mail and The Canadian Press. Carney said the cause is still under investigation and that the government will provide the resources to finish the probe “thoroughly and quickly.” He said the four soldiers killed will be among the names Canadians carry this Remembrance Day. “These were sons, brothers, partners, and friends,” Carney said. Conservative Leader Pierre Poilievre, who represents the riding that includes the base, spoke from Wainwright and said 19 of the 39 injured are in life-threatening condition, eight are stable in hospital and 12 are receiving outpatient care, which matches the figures given by the province on Sunday. He said some of the burn patients could need weeks or months of intensive care. Rutland has said officials had known about the fire for several hours and believed it was contained before the wind shifted, and the investigation is expected to examine the circumstances. Earlier, see our report Military names four soldiers killed in CFB Wainwright fire and our story on the RCMP’s involvement in the probe.

Earlier update, Oct. 19, 2026, at 8 a.m. MT: The Canadian Armed Forces will hold a board of inquiry into the fire, which Maj.-Gen. Wade Rutland said will take at least a month, CTV News reported. Rutland told a Sunday news conference that the cause is still under investigation, that officials do not believe oil and gas infrastructure or outside interference was involved, and that the fire was about a kilometre away when the wind shifted and drove it toward the unit’s administrative area. He said it is “not normal for a fire to move a kilometre in 30 to 60 seconds,” according to CTV News. Rutland said Charlie Company of 3 PPCLI, which has about 84 soldiers, was on a grenade range and conducting a section attack when the fire started, during high-intensity training ahead of a deployment to Latvia, CTV News reported. A correction to our earlier figures: Acute Care Alberta CEO Dr. Sayeh Zielke said of the 39 injured, 19 were in critical condition, eight were stable and 12 were ambulatory patients receiving care without being admitted, so not all 39 were hospitalized, CTV News reported. Smith said all patients are accounted for. The province’s Code Orange alert, in place for more than 10 hours, was lifted shortly before 1 p.m. on Oct. 18, CTV News reported.

Earlier update, Oct. 19, 2026, at 6:55 a.m. MT: National Defence has officially named the four Canadian Armed Forces members killed: Sgt. Morgan Wong of the Loyal Edmonton Regiment, serving with 3rd Battalion, Princess Patricia’s Canadian Light Infantry (3 PPCLI), and Ptes. Shaun Farrell, Aidan Goulding and Hayden Lykkemark of 3 PPCLI, all based in Edmonton, National Defence said in a Sunday news release. The department said the fire started during live-fire training under Exercise APOLLO SHOOTER and that high winds let it spread rapidly and overtake the unit’s administrative area. Thirty-nine members were injured. See our full report, Military names four soldiers killed in CFB Wainwright fire.

Defence Minister David McGuinty confirmed Saturday that people were killed and injured after an explosion and a major fire at Canadian Forces Base Wainwright in east-central Alberta, The Canadian Press reported.

Earlier update, Oct. 18, 2026, at 8:55 a.m. MT: National Defence published an official news release saying the fire started at about 4 p.m. local time Saturday in the training area at CFB Wainwright and moved quickly beyond the training area’s boundaries. The Canadian Armed Forces confirmed the incident caused deaths and injuries, said the full extent is still being assessed and said it will not release casualty or injury details until next of kin have been notified. In the release, Defence Minister David McGuinty said federal partners, including Public Safety, are working with the Alberta government and municipalities, and offered his thoughts to the families. Chief of the Defence Staff Gen. Jennie Carignan offered condolences to the families of those who died, and Canadian Army commander Lt.-Gen. Michael Wright expressed sadness over the loss of life and injuries, National Defence said. Official casualty figures were released later Sunday, as noted above.

Earlier update, Oct. 18, 2026, at 8:05 a.m. MT: The Canadian Armed Forces issued a Sunday morning update saying the situation continues to evolve and that it will not confirm details until next-of-kin notification is complete, Global News reported. Officials had not yet released casualty figures, a cause or names at that point. Figures and names have since been released, as noted above.

The Canadian Armed Forces has confirmed fatalities and injuries but has not released numbers, according to Global News. The outlet reported that the military’s Sunday update said the situation “continues to evolve.” Global News said it was relying on unnamed military sources for casualty figures and a possible cause, and neither has been confirmed by National Defence or other officials, so Canada News Media is not reporting them.

The Municipal District of Wainwright said the fire had crossed the base fence Saturday, and Global News reported that by around midnight it was being held, with a fire watch set for overnight. Global News also reported that several Alberta hospitals declared a Code Orange, a mass-casualty alert, and that Acute Care Alberta urged people to avoid the University of Alberta Hospital emergency department. Families seeking information can call the Family Information Line at 1-800-866-4546, according to Global News.

Carignan called it a “serious incident at CFB Wainwright” and said the military’s priority is its members, their families and the community, CBS News reported. She later said on X that the Canadian Armed Forces is “fully engaged” with federal, provincial and local authorities, according to Global News. McGuinty said Saturday night he could not recall an incident like this in recent memory and that the Canadian Armed Forces, National Defence and the federal government would share more “in the coming days,” Global News reported. He did not confirm whether weapons or ammunition were involved, CTV News reported. CBS News reported that the RCMP is involved and that no evacuation order was in effect.

STARS Air Ambulance sent crews from its Edmonton and Saskatoon bases as part of the multi-agency response, according to Global News. Elections Alberta closed the advance voting location at the Wainwright Communiplex early Saturday because of the fire and redirected Electoral Division 86 voters to Lloydminster and Vermilion, Global News reported. Monday is voting day in the Alberta referendum.

Some outlets cited unnamed military sources on Sunday for casualty numbers that differed from the official count. Global News reported at least seven dead on that basis, while Carney and Smith confirmed four dead and 39 hospitalized. Canada News Media is reporting the official figures.

McGuinty, speaking to reporters in Ottawa, said he had no other details to share, including the number of casualties or what happened, according to The Canadian Press. He would not confirm how many people died, calling it a “very active and delicate situation,” CTV News reported.

Prime Minister Mark Carney said in a social media post just after 6 p.m. that a “serious incident creating a major fire occurred at CFB Wainwright,” CBC News reported. “Our thoughts are with all the brave women and men affected,” Carney wrote. “We are working closely with the Government of Alberta and local authorities.”

Alberta Premier Danielle Smith said in a post on X that the province was “learning of a significant and tragic fire that is affecting many of our brave military personnel,” according to CBC.

The base is about 200 kilometres southeast of Edmonton. Fire crews were battling a blaze between the base and the nearby town of Wainwright, CP reported, as large parts of the province were hit by a windstorm with gusts of up to 100 km/h. McGuinty said he understood the town was not threatened and was helping the base with the injured and the fire, according to CP.

The Municipal District of Wainwright said the fire south of town “crossed the base fence earlier today and is being actively managed,” CBC reported. The municipality set up an emergency co-ordination centre, told people to avoid the area and keep roads clear for emergency vehicles, and asked residents not to visit the Wainwright Health Centre unless they have a critical medical need.

Acute Care Alberta said around 6 p.m. MT that Emergency Health Services was on scene “supporting care and transport related to an incident at CFB Wainwright,” according to CBC. Conservative MP Dane Lloyd said in a social media post that he had heard of “significant casualties” after an explosion and fire at the base, CBC and Global News reported.

Officials have not determined what caused the fire and explosion. Rutland said Sunday the investigation will examine terrain, field conditions and vegetation, and that he did not believe oil and gas infrastructure or outside interference was involved, CBS News reported. A National Defence spokeswoman said the government would release more information as it becomes available, according to reports. National Defence has since named the four members killed, as noted at the top of this story.

CFB Wainwright is one of the Canadian Army’s main training areas and regularly hosts large exercises with allied forces. The incident came on a day of high winds across the province, after Environment Canada issued wind warnings for southern Alberta, as we reported earlier Saturday. French-language searches for “incendie” rose in Canada Saturday evening as Quebec outlets reported the fire, according to Google Trends. The incident follows a severe national wildfire season, with wildfires burning 4.5 million hectares across Canada in 2026.
