The Saskatchewan Real Estate Commission requires commission to be agreed in writing before a trade takes place, though it regulates licensees rather than setting or publishing rates, so the exact arrangement varies by transaction and by brokerage.
There are exceptions. Some buyer representation agreements include a clause where the buyer covers a shortfall if the seller's offered commission falls below what the buyer's agent charges, so read that agreement closely, ideally with your own lawyer, before you start touring homes.
Ask your agent directly how they are compensated on a specific deal, alongside your own legal fees of $800 to $1,500, before you make an offer, so there are no surprises at closing.
