Instead of an annual cap, Saskatoon's assessments hold steady across a full revaluation period and then move in one step when the next cycle lands, which is why a notice can feel dramatic in the last year of a cycle and mild in the first. There is no yearly ceiling smoothing that jump the way a capped system does elsewhere.
If your assessment jumped sharply between cycles and you believe the new figure is wrong for your specific property, the remedy here is an appeal to the Board of Revision within the deadline printed on the notice, not a cap that limits the increase automatically.
None of this changes what your home would actually sell for today, since assessment and market value are measured differently in Saskatchewan. Get your hand-reviewed valuation from Joel Dyck.
