The problem with AirBnb is that if you live anywhere in the downtown core (particularly King West in Toronto), you're likely to encounter AirBnbs being rented out to parties. And especially on a consistent basis. It's extremely annoying in condos when you have loud obnoxious guests who rent it for a weekend night not just in their units, but in the hallways.

Not to mention, that consistently in a condo that my family owns, we consistently see weekend warriors leaving empty beer bottles and garbage in the elevators and condos.

Yeah, it's not technically AirBnb's fault or even necessarily the condo board's fault. It's partially a result of living in an area with irresponsible young people combined with short-term renters who don't care. But when rules, bylaws, and laws have no real teeth, people aren't incentivized to actually deal with the problems that neighbouring tenants face.
