Quick Summary

A fire at a Canadian Armed Forces training ground in Wainwright, Alberta, on Saturday resulted in four fatalities and 39 injuries. Online misinformation has spread, claiming that an explosive round from a live-fire drill hit a gas well causing an explosion. However, military officials state that strong winds caused a nearby grass fire to rapidly approach soldiers who were conducting training exercises, with no evidence pointing to natural gas infrastructure involvement. The Alberta Energy Regulator confirmed it has not received any reports of incidents related to oil and gas infrastructure at the base.
