A preliminary investigation into the deadly fire at CFB Wainwright suggests a munition from a live training exercise sparked a fast-moving grass fire, causing Saturday’s explosion, according to multiple military sources.
On Sunday, Prime Minister Mark Carney confirmed that four service members perished and their next of kin have been notified, adding that dozens more were seriously injured.
Separate military sources told Global News that at least seven people died and dozens more were injured at the base, located around 200 kilometres from Edmonton.
The Department of Defence and Alberta Premier Danielle Smith are slated to hold a news conference at 3 p.m. MT.
Here are the latest developments (all times local to Alberta):
1:35 p.m.
Alberta health officials say they have ended the Code Orange alert that was invoked Saturday night for some hospitals in Edmonton and elsewhere.
Code Orange is a call for hospitals to essentially clear the decks, find staff and free up beds as necessary to handle a mass casualty incident.
The province says its response to Saturday’s fire involved 22 ground ambulances, six planes and two helicopters, and included help from Saskatchewan.
The patients in Wainwright have now been moved to four hospitals: two hospitals in Edmonton, one in Red Deer and one in Calgary.
1:30 p.m.
Gil McGowan, organizer of a pro-Canada rally currently underway at the legislature in Edmonton, says the Wainwright tragedy “hangs like a real dark cloud” over the event.
McGowan, the head of the Alberta Federation of Labour, says the way first responders from around Canada selflessly stepped up to offer aid is a poignant reminder of why Canada is better united.
Albertans vote Monday on whether the province should stay in Canada or whether it’s time to hold a second, binding referendum on leaving Confederation.
Polls of Albertans before Premier Danielle Smith called the referendum and since then have indicated strong support to stay in Canada.

Wainwright Mayor Bruce Pugh, in an interview, says he knew something was wrong Saturday afternoon when the regular window-rattling boom of artillery that inaugurates the start of military training exercises at CFB Wainwright suddenly fell silent.
Immediately after, he says, there were sirens and the sound of helicopters racing in.
He says that just before midnight military medical personnel literally dropped from the sky to help, their red parachutes illuminated by flare lights.
