Because Warman sits outside Saskatoon's boundary, City of Saskatoon rules do not apply there. Warman has its own assessment, its own Board of Revision, and its own property tax and mill rate, distinct from anything inside the city.
Buyers choosing Warman are usually trading a highway commute for newer housing stock and lower entry pricing than a comparable Saskatoon suburb, a tradeoff worth running against real numbers before deciding.
