Quick Summary

A sudden wind change caused a grass fire during a live-ammunition training exercise at CFB Wainwright in Alberta, resulting in the deaths of four soldiers and injuries to 31 others. The incident occurred on Saturday despite initial low fire risk conditions; strong winds up to 100 km/h contributed to the rapid spread of the blaze. The Canadian Armed Forces memo released Sunday details that the fire jumped a fire guard and forced evacuation of nearby homes, with casualties primarily from C Company, Third Battalion of the Princess Patricia’s Canadian Light Infantry. Prime Minister Mark Carney described it as one of the worst peacetime tragedies in Canada's history.
