In many U.S. cities, the long term rental market has slowed down. Much commerce is at a standstill. That means no one is interviewing to hire. People have lost their job or are nervous about losing their job.Additionally, what you will also see is that more Toronto condo owners will pull units off of Airbnb and migrate them over to long term rental market.
Give it a year or so until the worldwide economy rebounds and travel to Toronto increases. You will see condo owners jumping back into the Airbnb market real fast.
Just like the 2009 recession, people will move back home or double up with friends. It has a sharp and noticeable impact on rents and vacancies.
