Most Saskatoon listing agreements are exclusive right to sell, typically for a 90 to 180 day term, because it gives the agent full incentive to market the property hard without worrying that the seller will quietly sell around them.
An exclusive agency arrangement can suit a seller who already has a likely buyer lined up, such as a relative or a tenant, and only wants professional help if that private deal falls through. The tradeoff is that the agent may market it less aggressively, knowing the commission is not guaranteed either way.
Read the definitions section of the agreement rather than assuming, since the two forms create very different incentives for the same signature. Get your hand-reviewed valuation from Joel Dyck.
