Reading Your Property Assessment Notice

Every four years, we mail a Property Assessment Notice to every property owner in Ontario. Your 2016 Notice reflects the assessed value and classification of your property as of January 1, 2016. We continue to update property information during non-Assessment Update years. Notices are mailed to property owners throughout the year to inform them of changes made to their property information.

You can also see how your property value has changed since the last assessment.

The Assessment Overview shows the assessed value on Jan 1, 2016 and Jan 1, 2012 and the difference between those values.

Phase in

If your property value has increased, you'll see the phase-in schedule for applying that value. We will phase in the increase gradually over four years, however if your property value has decreased we apply the decrease immediately. 

To learn more about how we phase in an increase in property value or apply a decrease, please see How Phase In works.
