Supplementary Tax Bills

Supplementary tax bills are issued when there has been a change in the assessed value of your property outside of the regular assessment cycle and additional taxes are owing. The Municipal Property Assessment Corporation (MPAC) provides the Township with the supplementary or omitted assessment values for the current year and up to two years prior when:

  • Land value is omitted from the assessment roll
  • Use of the property changes
  • Property is improved due to construction, addition, or renovation

You will receive a Property Assessment Change Notice from MPAC informing you of the supplemental or omitted assessed value and date. Supplementary and omitted property tax bills are typically due in two instalments regardless of the number of years for which you are billed.

Contact MPAC at 1-866-296-6722 or MPAC online for more details on how your property is assessed.

Estimate your Supplementary or Omitted Tax Bill
MPAC determines your assessed value. If you have not received your notice of supplementary assessment value from MPAC, you can use your purchase price as a guide to help you set aside funds in anticipation of receiving a supplementary or omitted tax bill. As an estimate, multiply the purchase price (or supplementary assessment value) by the applicable year’s tax rate.
Current Assessment Value

The Municipal Property Assessment Corporation (MPAC) is responsible for assessing all property in the Township. Its main responsibility is to calculate assessed values and to classify properties according to their use. These values are provided to the Township on the annual assessment rolls. The Township, County and the Province use these values when calculating property taxes and education taxes.

Tax Account Information

How do I change my address?
 To have property tax bills sent to a different address, submit a completed online Change of Address Form.
I am selling my property and only want to pay the taxes I owe, how can I do this?
Your lawyer will calculate your per diem tax amount (the exact amount you owe up until the day the sale closes) and be in contact with you. The Township is not involved in calculating your per diem tax amount.
Why did I receive a tax bill when I am on the PAP plan with the Town or my Mortgage holder?

You will still receive a tax bill if you are enrolled in the preauthorized payment plan. Your enrolment status will be indicated on your tax bill under your mailing address on your remittance stub(s) that will say "DO NOT PAY, you are on our PAP plan". If your mortgage holder pays your property taxes on your behalf, tax information along with due dates will be sent to the Mortgage company. Once paid in full, a final tax invoice will be sent to you updated with a paid stamp. If you received an arrears notice, please contact the tax department for further information.

Oops! I missed my preauthorized payment. What do I do now?

You will receive a letter advising that a payment has been returned by your bank. A fee of $25.00 is applied to your account. Payments are only attempted through PAP once – otherwise payments will need to made through any of the other available payment options. If the payment remains outstanding, the PAP will be cancelled due to non-payment. If any two payments are returned by your bank, the PAP plan will be cancelled. To reactivate your PAP plan, your account will need to be brought up to date.

Help! I made a duplicate payment on my property tax account

If you have made a duplicate payment on your taxes, you can get a refund returned to you or leave as a credit balance to be applied towards upcoming tax installments.

Please submit your request for refund in writing to finance@adjtos.ca. We will prepare a refund and send a cheque to the property owner(s) and mailing address on file.

I paid on time, why did I get charged penalty interest?
It is the Township’s policy to impose a penalty charge if payment is not received by the specified due date. If you paid your bill via internet banking, or at your banking institution on the day in which the amount was due, there is no guarantee that we will receive the payment that day as there is usually a 2-3 business day processing period, which means we will likely receive it late.

If you make your payment(s) online or at your bank, please ensure that payment is applied to your property tax account and not mistakenly against your utility account as these are separate accounts within the Township. 

My children attend school at a Public School, how do I change  my schoolboard taxes to go to that Board?

MPAC (Municipal Property Assessment Corporation) has an online School Support Portal. The portal is accessible by visiting https://www.mpac.ca/en/MakingChangesUpdates/SchoolSupportDesignation or mpac.ca. The portal enables residential property owners to add or update their school support designation information through AboutMyProperty. Tenants registered with MPAC will follow a different path in the portal, similar to voterlookup.ca, to add or update their school support designation information. 

Tax Certificates

Tax certificates are available upon request and payment of the applicable fee of $50.00 per roll. Once completed the Tax Certificate, Water Certificate (if applicable) and Receipt of Payment is sent via fax and mail. Response time is within 10 business days from receipt of request and payment.

Resolving Assessment Concerns

Accurate assessed values are the cornerstone of the property tax system. The Municipal Property Assessment Corporation (MPAC) assesses all properties in Ontario.

You must ask yourself if you can sell your property for its assessed value. If your answer is ‘yes’ your assessed value is accurate.

If your answer is ‘no’ you can:

  1. Ask MPAC to review your properties assessed value. Visit www.mpac.ca or by calling 1-866-296-6722 (Monday to Friday 8:00 a.m - 5:00 p.m)
  2. File a Request for Reconsideration with the Assessment Review Board (ARB).
