Assessment information

Assessment values on your property are updated by the Municipal Property Assessment Corporation (MPAC) usually every four years. Assessment increases are phased-in over the four-year period. Decreases in assessment are implemented immediately.

MPAC administers a uniform, province-wide property assessment system, which determines current value and classifications for all properties in Ontario. The authority to do so is in accordance with the provisions of the Assessment Act. The City of Vaughan does not determine these property value assessments.

2021 MPAC property assessment postponement and COVID-19

The Ontario Government announced that the 2021 Assessment Update has been postponed. Property assessments for the 2022 and the 2023 taxation years will continue to be based on the fully phased-in Jan. 1, 2016 current values. For more information, visit 2022 Property Assessment Notice | MPAC.

General assessment information
The last property assessment notices due to reassessment were mailed to residents in Vaughan on June 13, 2016. The values are utilized to calculate the municipal (City of Vaughan and York Region) and education portions (Province of Ontario) of the property tax bill for the tax years 2017 through to 2020 (now 2022 and 2023). An assessment increase does not necessarily mean your property tax will increase. When property values increase, the tax rate is adjusted down to accommodate the increase as the City of Vaughan receives the same total amount of tax dollar revenue.


With respect to residential properties, back in 2016, the average market change increase for the average house in Vaughan was approximately 34 per cent (four-year phase-in change was approximately 8.22 per cent), which means those who have an assessment increase above the average may see an increase on their tax bill and those who have an assessment increase less than the average could see a reduction on their tax bill, with respect to the reassessment impact only. For a detailed explanation of this process, watch the MPAC video: How Your Property Tax is Calculated.

If you believe your residential property assessment is incorrect in comparison to similar properties in your area, you have the option to submit a Request for Reconsideration through MPAC – who will review your assessment free of charge. The deadline to submit a Request for Reconsideration for the 2022 tax year is March 31, 2022, or the deadline that is printed on the Property Assessment Notice should you receive one.


Property owners are encouraged to visit to view a profile of their property and learn more about how their property was assessed. Video tutorials on How MPAC Assesses Property and the Reconsideration Process are available.
