What actually varies city to city is the combination of assessed value and mill rate, not a single comparable rate you can rank nationally. A Saskatoon home near the current benchmark of $444,700 can carry a very different bill from a similarly priced home elsewhere in the country simply because the two cities weigh services and levies differently.
A more useful comparison for a Saskatoon owner or buyer is your own bill against comparable Saskatoon properties, since that is the number an appeal to the Board of Revision can actually act on, not a national ranking that has no bearing on your specific assessment.
If you are weighing a move based on carrying costs, comparing actual notices for similar homes beats a national average every time. Get your hand-reviewed valuation from Joel Dyck.
