A supplementary property assessment is done when a new building, renovation or an addition to an existing building is completed in the current calendar year. The supplementary tax bill will reflect the number of months the building was completed or occupied during the year.

Provincial legislation requires that your City apply the same tax rates to supplementary assessments that were applied for annual property tax purposes. This includes both the Municipal tax rate and the Provincial Education tax rate.

Your assessment is an estimate of the price your property may have sold for on the open market by a willing seller to a willing buyer, as of July 1, of the previous year.

​"Market Value is the amount that a property...might be expected to realize if sold on the open market by a willing seller to a willing buyer."
Municipal Government Act Section 1(n), Province of Alberta.

Municipalities are required to reassess all properties annually. Your current assessment is based on the market value as of July 1 of the previous year.


Assessed values are reviewed at three points in the valuation process:

  1. By the City's internal checks and balances
  2. By the Alberta Government's annual assessed audit process
  3. By individual property owners' review of their notice
