The Municipal Property Assessment Corporation (MPAC) prepares property assessments. Township of Severn uses the current phase-in assessment and classification of properties to set municipal tax rates and collect property taxes.

Supplemental tax bills

You may receive a supplemental tax bill because MPAC has made a change to your property’s assessment value. This value is what is used to calculate your property taxes. This supplementary tax bill is in response to a Property Assessment Change Notice that you should have received from MPAC. 

What's a Property Assessment Change Notice?

If your new home was recently built or if you’ve completed renovations to make your new home your own, you’ll receive a Property Assessment Change Notice (PACN).

MPAC sends these notices each month between April and November.

You may receive a PACN if:

  • there was a change to your property such as an addition, new construction or renovation
  • MPAC assessed a structure like a pool, or a garage, for the first time
  • there was a change to your property’s classification (e.g., if you built a new structure on your property to run a business, that new structure may be classified as commercial)
  • your property, or part of it, no longer qualifies for a tax incentive for farmland, conservation land, or managed forest
  • your property, or part of it, no longer qualifies as tax exempt (e.g., you converted an old church into your dream home)

Your PACN includes the updated assessed value and classification as a result to any changes to your property.

If you disagree with the assessment increase, have questions, or did not receive your PACN, please contact MPAC directly at 1-866-296-6722. Township of Severn cannot respond on behalf of MPAC

Property tax appeals

If you believe your property assessment is incorrect, please contact MPAC to request a review of your assessment.

If you are not in agreement with the outcome of MPAC's review, you can then file an appeal with the Assessment Review Board—an independent tribunal of the Ontario Ministry of the Attorney General.
