Relationship between assessment and tax

What is a property assessment?

Your property 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. Assessed values reflect the physical condition of the property as of December 31, of the previous year.

Property Assessment Appeals

Property owners have 60 days after the assessment notice date to make a complaint about their property assessment amount.

Property assessment notices are mailed in January so property assessment appeals can be handled before tax notices are issued. Property assessment amounts may be appealed, property tax amounts are not appealable.

Assessment Review Board


Since 1995, Provincial legislation states that municipalities must use market value assessments to determine each property's fair share of revenue requirements from property taxes for municipal and provincial education services.

The market value standard has been used around the world since the 1970s. It is considered to be the most fair, equitable, and transparent manner to distribute property tax revenue requirements.

Market value assessment is a method that reflects the relative economic capacity and ability of property owners to pay taxes.
