They have started cracking down on regulations here as well. This last March there was a fire in a building in Montreal where it was found to be many illegal short-term rentals. Several people died in the fire. Some of the listings showed rooms with no window, so no possible escape.
One of the problems is that city councils do not have the personnel to keep up with all the listings, licenses and inspections. They want to put the onus on Airbnb to make sure the permit numbers are legitimate, but of course Airbnb does not want that responsibility, saying they are just a listing agent, and assume all permits are vetted.
I admit to never checking to see if I have rented a legal listing. I have never asked for a permit, or checked to see if it was legitimate.
Out of curiosity, I checked in my home town, and found a rental just up the street. I did not know it was listed, and do not see anywhere for a permit to be listed or checked. So there is no knowledge of any safety alarms, the legality of the suite, etc. This is concerning.
At least we know hotels have to pass safety inspections, and pay a tourism tax to the local government.
