MONTREAL -- Montreal’s mayor vowed Monday to tighten regulation of Airbnb as a search continued for six people missing after a fire swept through a building that included Airbnb units in a historic city section where they are banned.

Firefighters initially thought there was one person missing in the blaze Thursday in the eastern Canadian city. However, reports emerged later of illegal Airbnb units in the more than 130-year-old building, and authorities updated the missing over the weekend to seven, including some from the United States.

Montreal police reported pulling the body of a woman from the rubble Sunday evening.

Montreal police Inspector David Shane said the six who are still missing are from Quebec, Ontario, and the U.S., adding that investigators have contacted their families. The fire also injured nine people, including two who were hospitalized.
