Fire at Canadian military base kills four, injures 39
A grass fire swept through Canadian Forces Base Wainwright on Saturday, with Prime Minister Mark Carney calling it one of the worst peacetime military tragedies in Canadian history.

What happened
A grass fire broke out around 16:00 local time on Saturday at Canadian Forces Base Wainwright in rural Alberta, igniting on a training range during live firing exercises. Uncommonly strong winds caused the fire to spread rapidly and shift direction toward soldiers conducting exercises. Four service members—Sgt Morgan Wong, Pte Shaun Farrell, Private Aidan Goulding, and Pte Hayden Lykkemark—were killed, with 39 others hospitalized, 19 in critical condition. Many suffered severe burns. Royal Alexandra Hospital in Edmonton activated a code orange disaster protocol, deploying 22 ambulances and eight aircraft over a 10-hour emergency response.
Context
Canadian Forces Base Wainwright is one of the Canadian Army's busiest training bases, located 120 miles from Edmonton and 180 miles from Calgary in Alberta, with over 1,000 personnel stationed there at any given time. The base also hosts Royal Canadian Air Force operations. The scale of casualties and the severity of burns among the injured indicate intensive ongoing medical care will be required. Prime Minister Carney characterized the fire as violent and fast-moving, with military and civilian crews fighting it through the night in severe conditions.
What's disputed
The initial cause of the grass fire remains under investigation. Local media initially reported it may have been started when a gas main was struck during the live firing exercise, but military investigators later stated they do not believe any explosions were caused by oil or gas infrastructure. The defence ministry has found no indications of terrorist activity.
