Last updated: Sunday, Oct. 18, 2026, 12:45 p.m. MT. Officials are expected to give a detailed briefing in Wainwright this afternoon.
Four Canadian Armed Forces members are dead and dozens more are seriously injured after a fire tore through a training area at CFB Wainwright in east-central Alberta on Saturday.
Prime Minister Mark Carney confirmed the deaths in Ottawa at about 10 a.m. Mountain time Sunday. Their families have been notified. The dead have not been named.
“Yesterday afternoon, a violent, fast-moving fire swept through Canadian Armed Forces Base in Wainwright, Alberta,” Carney said. “What followed was one of the worst tragedies for the forces on Canadian soil in peacetime.”
The Department of National Defence says the fire started inside the base’s training area at about 4 p.m. Saturday and “spread rapidly beyond the boundaries of the training area.” The military says the full impact is still being assessed.
The confirmation comes about 15 hours after Defence Minister David McGuinty first said there were “both fatalities and injuries” but gave no numbers. Read our report on McGuinty’s late-night news conference.
“The nation is in mourning”
Carney said those affected came from bases across the country and included reservists and soldiers from the Princess Patricia’s Canadian Light Infantry, the infantry regiment based in Edmonton and at CFB Shilo in Manitoba.
He said military and civilian crews fought the fire through the night “in some of the worst conditions imaginable.” Paramedics, nurses and doctors in Wainwright, Edmonton, Red Deer and Calgary are treating the wounded.
“The people of Wainwright are taking care of their own,” Carney said, thanking those giving blood and “feeding and housing the emergency crews.”
“Those we lost and who were injured were training to defend Canada. To serve Canada. Now Canada serves them.”
Flags are at half-mast on federal buildings. Premier Danielle Smith has ordered the same for provincial buildings.
Families are starting to speak. An Ontario woman told CollingwoodToday her eldest son, who serves in the military, was critically injured in the fire.
A town that lives with the base
In Wainwright, this is personal. The town of about 6,600 sits right next to the base gate, and many residents serve or used to.
Mayor Bruce Pugh told Global News the person who lives across the street from him is a serving member. He said the Canadian Armed Forces is “like a family, very similar to this community.”
Residents told Global they could hear the exercises Saturday until they went quiet. Then came the sirens.
What caused the fire at CFB Wainwright?
The cause is under investigation. The RCMP is involved, and the military says there is no indication of terrorism.
Global News, citing multiple Canadian Armed Forces sources, has reported two versions. One says live fire from a training exercise struck a gas line or gas well on the base, causing an explosion. The other, attributed to a preliminary investigation, says a munition from the exercise started a fast-moving grass fire, which then caused an explosion.
Neither has been officially confirmed. The military has not said what training was underway. Past exercises at Wainwright have involved artillery and armoured vehicles.
Global reported, citing the federal government, that there are more than 200 active gas wells and pipelines in the area. No official has connected them to the fire.
Environment Canada had a wind warning in place Saturday, with gusts up to 100 km/h. Our Saturday coverage has more on the windstorm and how fast the fire spread.
People nearby heard it happen. A man who lives near the base told CBC News he heard “booms” all morning, which is normal during exercises. In the mid-afternoon he heard one huge “bang,” and then the noise stopped. The wind picked up, and later he saw smoke and fire from his house.
A veteran who lives in Wainwright told Postmedia he was at the base gym when it started. He said he knew live-fire drills were underway, and described a loud explosion and people with severe burns.
Hospitals under Code Orange
The Wainwright Health Centre took the first patients before they were moved to larger hospitals. Pugh told CBC it received four casualties and served as the initial triage point, calling it the “largest mass casualty event we’ve seen.” He told The Associated Press the small hospital was not built for this and praised its staff. At least 10 ambulances were parked outside Saturday night.
Global News reported that more than a dozen military personnel were parachuted into Wainwright late Saturday and went to the health centre.
STARS sent helicopters from Edmonton and Saskatoon. One landed at the University of Alberta Hospital, which has Edmonton’s burn unit. Smith thanked Saskatchewan for “additional air ambulance capacity.”
Acute Care Alberta declared Code Orange, the mass casualty designation, at several hospitals Saturday night and warned that “extremely few” ambulances were available in the Edmonton area.
Dr. Warren Thirsk, an emergency physician at the Royal Alexandra Hospital, told CBC both the Royal Alex and the University of Alberta Hospital were under Code Orange. He called it “a one in every 15- to 25-year disaster.”
“It is more patients than any of us want to count right now,” he told The Associated Press.
Canadian Blood Services says it is monitoring supply in Alberta and has donation appointments open.
Wainwright fire being held, officials say
The Municipal District of Wainwright said by late Saturday the fire was being held and property was protected. Global reported it was contained around midnight. Crews kept a fire watch overnight. No evacuation order was issued.
On Sunday morning, a CBC reporter at the edge of the base found a fresh fire break and charred land inside the boundary.
The fire also closed the Wainwright Communiplex advance poll on Saturday, the last day of early voting in Alberta’s referendum. Voters were redirected to Lloydminster and Vermilion. Monday’s vote runs 9 a.m. to 8 p.m.
Briefing in Wainwright this afternoon
McGuinty flew to Edmonton on Sunday morning. “To the families and everyone in Wainwright: Canada stands with you,” he posted.
Carney has asked senior officials “on the ground in Wainwright” to give Canadians a detailed account this afternoon. The briefing will include McGuinty, Emergency Preparedness Minister Eleanor Olszewski, Maj.-Gen. Wade Rutland of the Canadian Army, and provincial ministers. No time has been announced.
Smith is in Edmonton and has convened her emergency management cabinet committee. “The loss of life and injuries are heartbreaking,” she said.
About CFB Wainwright
CFB Wainwright, about 200 kilometres southeast of Edmonton, is one of Canada’s busiest army training bases. About 1,300 military and civilian staff work there. It covers about 609 square kilometres and houses the Canadian Manoeuvre Training Centre, where units train together under realistic battlefield conditions, the 3rd Canadian Division Training Centre, and about a dozen other units.
The base has seen fatal training accidents before, most recently in 2014, 2017 and 2020, each involving one death. The deadliest Canadian military training accident in recent decades was at CFB Chilliwack in B.C. in 1988, when six students were killed in an explosives training accident.
