Any occupation where there is a risk of personal (or pecuniary) injury to the client should (and does) require some form of licensing. The license ensures that a minimum standard of competency has been met by the person offering the service.
But we found that an Uber drive isn't meaningfully more dangerous than a licensed taxi drive. And an Airbnb stay isn't meaningfully more dangerous than a licensed hotel stay.
Closer to home, in my province, there have been issues with AirBnB operators not being properly insured. If you were injured because of something unsafe on the property, compensation could be difficult or impossible. There have been instances of airbnb rentals that have hidden cameras in rooms you would assume to be private. I personally would feel safer if bad behaviour can get a person banned from renting rooms.
Anecdata, but what the fork was going on here? And do we think it would happen at a hotel? https://torontosun.com/news/provincial/hunter-toronto-woman-...
