The most relevant recent shifts for a Saskatoon homeowner run through CMHC's lending guidelines, which qualify a borrower around 39 percent of gross income on housing costs and 44 percent on total debt. Joel Dyck can point to whichever specific change actually affects your situation once you tell him what you are trying to do. Mortgage stress-test and qualification rules change more often than most homeowners track, and because they are set federally through CMHC rather than provincially, searching for a Saskatoon-specific 'housing bill' misses where the actual rule lives.
Property tax and assessment rules, by contrast, are a City of Saskatoon matter, reassessed on the City's own cycle and taxed on 80 percent of assessed value, which is a separate track entirely from anything happening at the federal mortgage-policy level.
If there is a specific change you saw referenced, naming it is the fastest way to get a straight answer instead of a general one. Get your hand-reviewed valuation from Joel Dyck.
