Major fire at Canadian Forces Base Wainwright in Alberta killed four soldiers and injured dozens, with at least 19 in critical condition. Prime Minister Mark Carney called it one of the worst peacetime tragedies for Canadian forces.
The fire broke out during high-intensity combat training with live munitions, spreading rapidly due to strong winds. Officials say it did not appear tied to terrorist activity, though cause is under investigation.
The incident has led to a coordinated emergency response, with hospitals activating 'code orange' for severe cases. Military and emergency crews worked through the night in challenging conditions to contain the blaze and assist the injured.
The fire's origin is still unclear, with officials noting it was not linked to oil and gas infrastructure or outside interference. Investigations continue into the cause of the blaze.
