That total is not commission alone. Commission in Saskatchewan is negotiable and often tiered, with a higher percentage on the first portion of the price and a lower percentage on the balance, so there is no single provincial rate to quote, and a seller should agree the exact structure in writing with their agent before listing.
Legal fees cover the lawyer's work at Information Services Corporation registering the transfer, along with the title search and payout of any existing mortgage, while other adjustments true up whatever the seller has already prepaid, like property tax, so the buyer does not pay it twice.
