How will reassessment effect my 2017-2020 taxes?

Halton Region has experienced higher market value increases than the province as a whole. Oakville’s market value increases are approximately 28 per cent. If your assessment has increased by more than 28 per cent you will experience an assessment related increase in your taxes that will be phased-in over the four year period.


2012 (old) market value — $600,000
2016 (new) market value — $850,000
Increase — $250,000

This example represents a 42 per cent increase or 10.5 per cent increase year over year from 2017 to 2020. The town’s overall average increase is approximately 28 per cent or 7 per cent year over year. If your assessment has increased more than the town’s overall average, you will have a property tax increase due to reassessment. The difference between the average town increase of 28 per cent and the increase of 42 per cent from the example above is 14 per cent. The 14 per cent difference will be phased-in over the four year period 2017 to 2020, or approximately a 3.5 per cent increase per year (excluding any budgetary related changes).

Please note that all percentages are estimates.

Deadlines for Request for Reconsideration (RfR) and/or appeal

If your property or a portion of it is classified as residential, farm, managed forest or conservation land for the 2018 tax year, the deadline to file a Request for Reconsideration (RFR) with the Municipal Property Assessment Corporation (MPAC) is included on your Property Assessment Notice. The Request for Reconsideration deadline for the 2018 tax year is April 2, 2018. If you submit a RFR, the last day to file an appeal is 90 days after the issue date listed on the RFR results letter you receive from MPAC. For all other property types, you may choose to either file a RFR with MPAC or file an appeal directly to the Assessment Review Board (ARB). The Request for Reconsideration deadline for the 2018 tax year is April 2, 2018, and the ARB Appeal deadline is April 3, 2018.

Tax information

Realty (property) taxes are levied by the town. Taxes provide the main source of revenue to deliver services supplied by the town, the region and school boards located in Oakville. Payment dates for tax payments are set in accordance with legislation that requires the Town to pay the Region of Halton and school boards a proportional share of the tax levy. Consequently, all tax payment options require that taxes are fully paid by September 30 annually.

Properties are assigned a tax class depending on the use or purpose of each property. Annual tax rates are set and applied to each tax class. The tax levy for property is calculated by using the applicable tax rate and the assessed value assigned to each property. To look up your property tax assessment use the Tax Assessment Comparison Tool. This tool contains assessment information for the 2018 taxation year. Additional assessment information can be obtained on the MPAC About my Property website.

Assessment information

The assessed value of a property is commonly referred to as the current value assessment or CVA. The CVA is an estimate of the market value of a property at a fixed point in time (the valuation date), or the amount the property would sell for in an open market on a given date (i.e. what a willing buyer would pay a willing seller for the property).

In Ontario, the Municipal Property Assessment Corporation (MPAC) assigns the assessed value and tax class to all properties every four years. Municipalities have no authority to assign, alter or change the assessed value or tax class of property.
