An explosion and fire in high winds has resulted in “significant casualties” at Canadian Forces Base Wainwright, located east of Edmonton, MP Dane Lloyd said in a social media post on Saturday night.

“Hearing terrible news out of CFB Wainwright,” Mr. Lloyd wrote. “Please keep our soldiers, their families and the community of Wainwright in your prayers. God be with them all.”

Minister of National Defence David McGuinty said he was saddened to share there have been “both fatalities and injuries.”

“I cannot recall an incident like this in recent memory,” he said. “This is a very, very active and delicate situation.”

Three military sources confirmed there are multiple fatalities. The Globe is not naming the sources, who are not authorized to comment publicly.

RCMP spokesperson Corp. Gina Slaney said she had been authorized to speak on behalf of the Canadian Forces, to confirm that a fire was reported at the base around 4 p.m., and had extended beyond the boundaries of the training area. She said she could not confirm injuries or fatalities, but that RCMP around the province had been called out to help.
