Four Canadian Service Members Killed in Alberta Base Fire

ReFour Canadian Service Members Killed in Alberta Base Fire

A fire during military training at Canadian Forces Base Wainwright killed four service members and injured dozens, prompting a mass-casualty response across Alberta hospitals.

Four Canadian service members were killed and dozens more were seriously injured when a fire broke out during military training at Canadian Forces Base Wainwright in Alberta, Prime Minister Mark Carney said Sunday. Carney described the incident as one of the country's worst peacetime military tragedies on domestic soil.

The fire erupted Saturday afternoon at the base, where fierce winds with gusts reaching up to 62 mph drove flames beyond the installation and into surrounding rural areas. The Royal Canadian Mounted Police said officers responded to reports of a fire in a training area shortly after 4 p.m. By late Saturday, local officials said the blaze was being held and that property and critical infrastructure had been protected. No evacuation order was issued for nearby residents.

Carney said in a televised address that the families of the four killed service members had been notified and that the situation was still evolving. Those affected included reservists and soldiers from Princess Patricia's Canadian Light Infantry, one of Canada's oldest and most storied military regiments. Personnel had traveled from bases across the country to take part in training exercises at Wainwright.

Defense Minister David McGuinty initially confirmed fatalities and injuries but did not provide a casualty count. He told reporters he could not recall a similar incident in recent memory. The exact number of injured service members remained unclear Sunday, with victims receiving treatment at hospitals in Wainwright, Edmonton, Red Deer and Calgary.

Several hospitals across Alberta activated a «Code Orange,» an emergency designation for mass-casualty incidents, as medical personnel scrambled to treat the wounded. Dr. Warren Thirsk, an emergency department physician at Royal Alexandra Hospital in Edmonton, told CBC News that the volume of patients was unprecedented for the city. «This number of patients would overwhelm the city of Edmonton,» Thirsk said. «It is more patients than any of us want to count right now. It's a disaster.»

Canadian military officials said there were no indications of terrorism, though the cause of the fire remained under investigation. McGuinty said the RCMP was involved in the investigation and described the situation as «very, very active and delicate.»

Cathy Keane, a mayoral candidate in Ontario, said on Facebook that her eldest son was among the military personnel critically injured. «As a mother, right now I need to be with my son and family,» she wrote, saying she was traveling to Alberta.

Carney announced that flags would fly at half-staff on federal buildings nationwide in honor of those killed and injured, and he praised emergency crews who battled the flames through the night. The fire spread into rural areas surrounding the base as crews worked under intense wind conditions, but officials said critical infrastructure was protected.
