Ontario’s Property Assessment and Taxation System
Property assessments are determined by MPAC.
Assessments are shared with municipalities.
Municipalities determine investments required to build thriving communities.
Your property assessment and the property taxes you pay are not the same thing.
The information on this page will help you better understand the relationship between your property’s assessed value and your property taxes.

Does an increase in my MPAC property assessment
mean my property taxes will go up?
Not necessarily. When a province-wide assessment update occurs, the most important factor is not how much your assessed value has changed,
but how your assessed value has changed relative to the average change for your property type in your municipality.
Explore the examples below to see how changes to property assessments can impact property taxes.

Questions about your property taxes?
Property taxes are calculated using the assessed value of your property and multiplying it by the combined municipal and education tax rates for your property class.
Your municipality or local taxing authority determines their revenue requirements, sets municipal tax rates and policies, and collects these property taxes to pay for your municipal services.
You can search for your municipality and contact them for more information about your property taxes.
