What a Saskatoon renter does pay, once approved, is a security deposit and the first month's rent, both due to the landlord directly rather than to a third party involved in the showing.
A tight rental market here shows up as a lower vacancy rate and more competition for a well-priced unit, not as an upfront cash requirement just to walk through the door, which is the mechanism actually driving that cost in the market the question is describing.
If you are an owner deciding whether a Saskatoon rental property is worth more rented out or sold outright at today's $444,700 benchmark, that is a very different comparison than a viewing fee. Get your hand-reviewed valuation from Joel Dyck.
