Questions raised about Airbnb rentals after Montreal building fire.

Six people, including Americans, are missing after a fire swept through a building that included illegal Airbnb units in Montreal's Old City, where short-term rentals are banned. The fire injured nine people, including two who were hospitalized, and killed at least one woman. Montreal Mayor Valérie Plante vowed to tighten regulation of Airbnb and work with the Quebec provincial government to enforce stricter regulations on short-term rentals. The cause of the fire is under investigation, and no one has been charged.
