Property Assessment and Appeals
The Municipal Property Assessment Corporation (MPAC) is responsible for assessing all properties in Ontario. Municipalities use this assessment in the calculation of property taxes (Explained in 'How Taxes are Calculated'). The assessment is calculated using property values, recent property sales and other pertinent information to establish a "market value" for each property. Property owners will receive a notice from MPAC advising them of their assessed property value. The notice will also include information on how to question that value or appeal for a change.
All property in Ontario is assessed once every four years by MPAC. Each property is assessed based on what fair market value a willing buyer would pay a willing seller for the property on a legislated valuation date.
To help provide property tax stability and predictability, the Ontario Government has introduced a phase-in program where market increases in assessed value between assessment cycles will be phased in over four years. The full benefit of a decrease will be applied immediately.
**If you have any questions regarding your assessment please contact MPAC at 1-866-296-6722 or refer to their website www.mpac.ca **.
Taxpayers can appeal their property assessment using the following forms:
