For an owner-occupied purchase with a legal secondary suite, lenders and CMHC generally treat that arrangement more favourably than a pure investment purchase, since you are living in part of the property and the suite income offsets your own housing cost. The suite still has to be a permitted, legal unit under City of Saskatoon rules for any of that income to count.
A pure rental purchase with no owner-occupancy is underwritten differently, and minimum down payment requirements are higher than the standard 5 percent to $500,000 then 10 percent above that applies to an owner-occupied purchase. Confirm with your lender early which category your purchase falls into, since it changes both your qualifying income and your required down payment.
