MONTREAL - Fire officials now say at least seven people are missing after a blaze destroyed a building in Montreal's historic district Thursday. “We want to announce tonight that we're gonna take down this building slowly, stone-by-stone, to make sure that the environment inside here is safe for all the people from the fire department and the police department to do their work,” said Guilbault. ”“In this sector (the site of the fire), it is not legal to have Airbnb rentals, but we will have to wait for the investigation to be over to find out whether that was the case here or not,” he said
