What is a Property Assessment?
Property assessment is the process by which a municipal or provincial authority determines the market value of a property for taxation purposes.
Why Does a Property Assessment Matter in Real Estate
In Canada, property assessments are conducted by provincial agencies (such as MPAC in Ontario or BC Assessment in British Columbia) or local municipalities. The assessed value is used to calculate annual property taxes.
Assessments are typically based on:
- Comparable property sales
- Property type and size
- Location and neighbourhood trends
- Renovations or structural changes
These assessments are updated regularly, often every 1–4 years. Homeowners receive a notice showing their property's assessed value and have the right to challenge it if they believe it's inaccurate.
Understanding your assessment is important because:
- It directly affects your property tax bill
- It may differ from market value
- Errors or overvaluations can be appealed
Accurate property assessments help fund essential local services like schools, roads, and emergency services.
Example of a Property Assessment in Action
A homeowner in Vancouver receives a 2025 property assessment notice showing an assessed value of $1,150,000, which will be used to calculate their annual municipal property tax.
