For a home sale in Saskatoon, that principle runs through the listing agreement rather than a rental bylaw. A seller signs with a listing brokerage and agrees in writing to a commission, which is negotiable and often tiered, a higher rate on the first slice of the price and a lower rate on the balance. The listing brokerage then shares part of that commission with whichever brokerage brings the buyer, so on a resale purchase the buyer typically owes their own agent nothing directly.
Saskatoon rentals work on the same hire-and-pay logic without needing a bylaw to enforce it. A landlord who engages a licensee to fill a vacancy pays that licensee under their own written agreement, and a tenant who separately hires an agent to find a rental pays theirs. What the Saskatchewan Real Estate Commission actually polices is disclosure and honesty in that agreement between the parties, not a set fee schedule, and it does not publish rates for either side.
If you are selling rather than renting, the practical question is what you net once that written agreement is signed. Joel Dyck puts a commission figure in front of you before you list, and seller closing costs, including that commission, run 4 to 6 percent of the sale price in total.
