Global News reports that when a customer saw smoke coming from the restaurant and called 911 a little after 5pm, people were still lined up, "oblivious to the situation." Once the eight or so firetrucks arrived, however, everyone got wise to the situation and self-evacuated.
Thankfully no one was seriously injured, though a firefighter suffered minor injuries that reportedly did not require hospitalization. Crews were seen working as late 2:30am.
While the building is basically gone, the franchise owner wants to rebuild.
"I've seen the pictures and it virtually burnt to the ground,” an A&W Canada spokesperson said to the Free Press, as cited by Munchies. “The franchise owner really wants to rebuild and there are a number of steps he'll have to go through, but he wants to get it [...] open this year.”
Considering demand is this high, we see his point.
