Summary

A grass fire at Canadian Forces Base Wainwright in Alberta on October 17, 2026 killed four members of the Canadian Armed Forces and injured 27 others. The fire began during training on the automatic grenade launcher range and spread rapidly as high winds pushed it across the training area, where firefighters could not directly combat it due to its location. Reports differ on the ignition source: one account attributes it probably to live rounds fired during drills, while the cause is described elsewhere as still unclear and under investigation. Military police and a board of inquiry are examining the circumstances. Some reports describe the fire as moving toward soldiers conducting the exercise, and others say it was monitored rather than suppressed while in a permanent danger area. Training at the base has resumed. Officials have not confirmed these accounts.
