Quick Summary

A fire at a Wainwright military base in Alberta killed four soldiers and injured 39 others, including 27 who required hospitalization. The incident occurred on Saturday during high-intensity combat training exercises involving live grenades for the 3rd Battalion, Princess Patricia’s Canadian Light Infantry. High winds caused by a change in wind direction intensified the fire, which spread to a training area despite efforts by firefighters who were restricted from directly combating it due to safety zones around the grenade range.

The deadly fire broke out on a grenade launcher range during military exercises on Saturday, with high winds propelling it across the base, Brigadier-General Vanessa Hanrahan, commander of the Canadian Forces Military Police Group, told reporters on Thursday. “A subsequent change in wind direction and velocity significantly increased the fire’s intensity,” she added, with the flames spreading to a training area at the Wainwright military base in Alberta.
