Extreme weather fuels deadly training-ground fire at Alberta base, killing four soldiers

A wildfire broke out during a live-fire training drill at CFB Wainwright in east-central Alberta on Saturday, quickly overrunning the area as a cold front shifted winds to near 100 km/h and temperatures fell from almost 20 °C to about 10 °C. Experts said the combination of dry grass, low humidity around 20 % and forecasted gusts created “extreme” conditions that allowed the fire to travel a kilometre in under a minute.

The blaze, which started as a grass fire, killed four soldiers and left dozens with serious injuries while troops were conducting grenade throws and a simulated attack. Maj-Gen. Wade Rutland said range control knew of the fire for several hours but deemed the training acceptable, and the cause remains unclear. Environment Canada had issued yellow alerts earlier, and both meteorologists and wildfire specialists say the weather warnings were issued well before the incident. Military police and the Canadian Forces National Investigation Service are now investigating the response and decision-making.
