Legality is the first gate, not an afterthought. Secondary suite permissions, parking requirements and separate egress are confirmed with the City of Saskatoon, and a suite that was framed in after possession without any of that is not income in a lender's eyes. Lenders commonly credit a portion of documented legal suite rent toward qualifying and credit an undocumented suite at nothing, which changes what you can borrow.
Then there is the ownership structure. A good share of Stonebridge is townhouse and apartment style condominium, where a bare land or conventional condominium corporation under The Condominium Property Act, 1993 can restrict rentals outright or cap how many units may be leased. Read the bylaws and the estoppel certificate before you assume you are allowed to rent at all, because that restriction survives your purchase.
If it clears both gates, the case for Stonebridge is stability rather than a fat yield. Newer building envelopes mean lower maintenance for the first stretch of ownership, tenancies run under The Residential Tenancies Act, 2006, and vacancy in a neighbourhood with this much retail and Circle Drive access tends to be low. Budget $400 to $600 for an inspection and $800 to $1,500 in legal fees, and have the property valued properly before paying a premium for a suite.
