A live-fire training exercise at Canadian Forces Base Wainwright in Alberta reportedly ended in a major explosion and wildfire Saturday, leaving at least seven people dead and dozens injured, according to local outlet Global News. 

The report said a projectile was fired during the FTX that struck “a gas line or gas well” within the base’s training area, triggering an explosion before strong winds spread the fire. 

🇨🇦 At least 7 killed, dozens injured at Canadian army base after live-fire exercise hits gas well An explosion and fire tore through CFB Wainwright in Alberta, the Canadian army’s main live-fire training base, on Saturday afternoon. Multiple military sources told Global News that at least seven people were killed and dozens injured. Local social media accounts claim over 100 injured. According to the same sources, a live-fire exercise struck a gas line or gas well on the range, triggering the blast. The base has had gas wells and pipelines running through its training area since the late 1980s. Strong winds pushed the fire past the base fence into the surrounding countryside, and NASA satellites picked up a line of hotspots across the range. Wainwright’s hospital was overwhelmed, and Edmonton hospitals declared a “code orange” disaster protocol as the wounded were flown in. Defence Minister David McGuinty confirmed deaths and injuries but gave no numbers or cause, saying he could not recall anything like it in recent memory.

Located about 130 miles east of Edmonton, CFB Wainwright is a major Canadian Army installation used to prepare troops for combat operations. 

Despite the information blackout, posts, rumors and minimal reporting indicate the Wainwright Incident began as a Canadian Forces live-fire exercise: 1. Temperatures exceeded 20°C with 20% humidity and gusts up to 100 km/h—fire weather in Alberta. 2. Artillery or other fire (one post says grenade launcher) apparently caused a grass fire that burned into an active natural gas well, or hit the well and caused an explosion that started the fire. 3. Winds drove this grass fire into a conflagration. Soldiers may have got caught in this. 4. The fire then burned into base ammunition storage, causing a mass casualty incident. 5. Extreme winds continue fueling rapid expansion as the fire spreads from federal land into the MD of Wainwright. 6. No Alberta Emergency Alert. Highly suspicious and shows at least a complete communication breakdown with the Alberta and Canadian governments. Gross negligence. 7. Albertans are dead, missing and injured en masse. A Code Orange (mass casualty alert) is in effect. This is a horrible tragedy. Praying for everyone affected. Why do this exercise in fire weather? Why the complete lack of information from the feds? The feds aren’t God. The longer they withhold pertinent information, the less I will trust Canadian governing institutions. Something is fishy here. Can’t put my finger on it. It must be gross incompetence. Right?

Bloomberg data shows its training grounds contain natural gas infrastructure, including wells and buried pipelines. 

NOVA Gas Transmission, called NGTL, appears to have a pipeline that runs through part of an area on the base called “Permanent Danger Area 3B H1.” 

“I cannot recall an incident like this in recent memory,” Minister of National Defense David McGuinty said.
