There is a growing supply of rental units in the city core:
1. Purpose built rental buildings coming on stream with hundreds of units, and more on the way.
2. Newish (last 5 years) condo buildings that still have units the developer can't sell without taking a big loss. Therefore some of them are being rented out short to medium term
3. Past condo owners who purchased units as an investment property, and have been renting them out for years. The Airbnb business has dropped substantially and will probably not recover for another year. Owners are forced to look for longer term tenants.
and ... will hotels realize that the only way to increase occupancy rates in the foreseeable future is to offer monthly rates??? If so, they will be in competition as well.
All of this supply and cost pressure will only lead to lowering of rents which is a good thing if you are a renter but very bad if you are a real estate investor.
