Assessment values on your property are updated by the Municipal Property Assessment Corporation (MPAC) 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.

2020 MPAC property assessment postponement and COVID-19

The Ontario Government announced that the 2020 Assessment Update has been postponed. Property assessments for the 2021 taxation year will continue to be based on the fully phased-in January 1, 2016 current values (i.e., the same valuation date in use for the 2020 taxation year). For more information, visit MPAC’s 2020 Assessment Update.

General assessment information

The last property assessment notices 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 including 2021). 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, 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, please watch the MPAC video, How Your Property Tax is Calculated.
