Who assesses property value and taxes
The Municipal Property Assessment Corporation (MPAC) assesses the value of your residential or business property. The City of Mississauga determines your property tax based on the property value assessment provided by MPAC.

Get tax information
If you own property in Mississauga, you can get information about your property tax from the Tax Office, 4thfloor, 300 City Centre Drive from Monday to Friday, 8:30 a.m. to 4:30 p.m.
Appeal assessment of property value
If you disagree with MPAC’s classification or assessment of your property, please contact MPAC directly at 1-866-296-MPAC (6722) with a Request for Reconsideration (RFR).
Businesses can appeal to the Assessment Review Board (ARB); an independent tribunal of the Province of Ontario without making a Request for Reconsideration.
Adjusting your tax account
The City can only adjust your property tax account after receiving notification of a decision from MPAC or the ARB for any change in the value of your property. To avoid any penalty or interest charges, we recommend that you continue to pay your taxes while your appeal is being assessed by MPAC or the ARB.
If you are selling your property while your appeal is under consideration, make sure your lawyer provides for the adjustment of any taxes after the closing date.
