Property Taxes

Due dates

Normally, property taxes are due twice per year:

  • Interim bill (calculated as 50% of the previous years' total taxes) – last business day of March
  • Final bill – last business day of August

Supplementary and omitted tax bills

We may also issue supplementary and omitted bills throughout the year. These bills are due within 21 days from the day we issue them. They show any additions or improvements to your property, which increase your property's assessment. Municipal Property Assessment Corporation (MPAC) determines its value.

Haven't received your tax bill?

Haven't received your tax bill and the due date is drawing near? Please call us at 705-687-3412 ext. 2227 or send us an email at We don't consider failure to receive a tax bill a reason for non-payment.

Tax refunds, reductions and rebates

We calculate your property taxes based on your property assessment, which is determined by MPAC. If you do not agree with your assessment, please contact MPAC directly.

You may qualify for a cancellation, reduction or refund of taxes, if:

  • Your building experienced a fire or was demolished
  • Your assessment contains a significant error that is clerical or factual in nature (this does not include errors in judgment in assessing the property; in this case, contact MPAC directly)
  • Your property could not be used for its normal use to do repairs or renovations for at least 3 months during the year
  • Your property was previously non-residential but has changed use in the year
  • Your property was granted exempt status in the year

Application for tax appeal

If you qualify for a cancellation, reduction or refund of taxes based on the above, please submit an application for tax appeal no later than the last day of February year after the application's year.

Provide details of your appeal

Please provide the details of your appeal along with copies of any relevant documents that support your appeal (e.g., demolition permit, contractor invoices, fire department report).

How property taxes are calculated

We calculate your property taxes using the current value assessment (CVA) of your property and multiplying it by the combined upper tier, lower tier, and education tax rates for your property's tax class.

Current value assessment (CVA)

A CVA is a dollar value assigned to your property, which MPAC determines. Please contact MPAC directly if you have any questions about your assessment or visit their website to find out how your property assessment is determined.

Tax rate

The overall tax rate applied to your property is made up of a combination of different tax rates: the education tax rate, the upper-tier tax rates, and the lower-tier tax rates. To find out which tax rate is applicable to your property, see our Tax Rates page.
