Canadian Prime Minister Mark Carney says a "serious incident" has caused a major fire at a military base in Alberta.
"A serious incident creating a major fire has occurred at CFB Wainwright, in Alberta," Carney said in a social media post.
"Our thoughts are with all the brave women and men affected," he said.
The Canadian Forces Base is near Wainwright, Alberta, a town about 180km southeast of Edmondton.
Alberta Premier Danielle Smith described the fire at is "significant and tragic" and said it was affecting many military personnel.
Carney said the federal government was working closely with Alberta officials and local authorities. He said he and Smith were in close contact, as were their ministers and officials.
Smith thanked first responders and those providing care and support to those affected.
Neither Carney nor Smith provided details about what caused the fire or whether anyone was injured.
Canadian Conservative Opposition Leader Pierre Poilievre said he had spoken with Carney and the defence minister to offer support to those affected by the fire.
"Pray for Wainwright, everyone," Poilievre said in a social media post.
He urged people in the area to follow emergency instructions and keep roads clear for first responders.
The fire came days before the province is set to vote on beginning a process that could lead to its seeking independence from Canada.
