County of Wellington Tax Rebate

The County of Wellington offers a tax relief program for low-income seniors and low-income persons with disabilities. The intent of this program is to provide a mechanism to assist those least able to pay a significant increase in taxes due to a reassessment. Applications must be received by the first of November of the taxation year in which the relief is being requested. For more information, please contact the Township of Mapleton's Finance Department at 519-638-3313 or visit the County of Wellington tax relief webpage.

Ontario Senior Homeowners' Property Tax Grant

In addition to the tax rebate offered by the County, the Province provides a grant to help low income seniors with the cost of their property taxes. For more information on the Ontario Senior Homeowners' Property Tax Grant program, please visit the Ontario Ministry of Finance website.

The Municipal Property Assessment Corporation (MPAC) has the role of accurately valuing and classifying properties in Ontario in accordance with the Assessment Act and the regulations established by the Ontario Government. MPAC provides a range of services including the preparation of the annual assessment rolls for use by municipalities and the Province of Ontario to calculate property taxes and education taxes. When your municipality/local taxing authority sets property tax rates, your assessed value and classification are used to determine your property taxes. An assessment increase does not necessarily mean your taxes will increase.

For questions about your property taxes, please contact the Township of Mapleton at 519-638-3313. 

For more information about MPAC, please call 1-866-296-6722.

To ensure your correct school support designation is provided to Elections Ontario in time for the next municipal and school board elections on October 26, 2026, it should be reviewed and, if needed, updated by June 1, 2026. 

While Elections Ontario maintains the Permanent Register of Electors in Ontario for provincial, municipal, and school board elections, MPAC (Municipal Property Assessment Corporation) is legislatively responsible for collecting school support designation information.  

What is school support?
Whether you own or rent your home, your property is linked to a school board – even if you don’t have children or your children aren’t currently attending school. While you’re not required to make a designation, you do have the option to choose which school board you support. If you don’t make a choice, your support will default to the English-Public school board.    

How to update school support designations
Property owners can change their school support designation online using MPAC AboutMyProperty™ or our online portal for tenants. To get started, choose the option that applies to you:  

• I am a property owner 
• I am a tenant 

A step-by-step guide is available in English or French. 

Please note: Registration may take up to 24 hours to activate. 

You can submit a paper Application for Direction of School Support form in English or French and mail or email it to MPAC. 

To learn more or update a school support designation, visit mpac.ca/schoolsupport.

The Municipal Property Tax Assessment Corporation (MPAC) will periodically notify the Township of additional or omitted assessment values on your property resulting in a supplementary / omitted tax bill being issued. The supplementary / omitted tax bill is in addition to what has been previously billed on the property. This bill does not include payments already made to your tax account or future installments that have been previously billed and are still outstanding.

If you received more than one bill, multiple years were affected. Each years’ taxes are calculated using the tax rate at the time. Each bill notes the change in assessment value along with the effective date of the change, and each bill covers from the effective date to December 31^st of that same year.

Reasons for Issuing Supplementary / Omitted Bills

You will have received a notice from MPAC notifying you of this change in assessment value.

This is usually due to building activity, new construction, renovations/improvements, or a reclassification of your properties tax class either for the entire property or a portion of the assessment such as changing from farmland to residential.

If you disagree with your assessed value or supplementary / omitted assessment, you can file a Request for Reconsideration (RFR). Please see your Notice of Assessment from MPAC for the deadline to file. Please contact MPAC at 1-866-296-6722 or visit www.mpac.ca for more information.

If you recently purchased farmland, made changes to your farmland ownership and are already taxed at the reduced farm property tax rate, or need an exemption, you must confirm your continued eligibility by completing an Eligibility Application which can be found by going to www.agricorp.com/farmtax.

Due to the recent change in ownership, it is possible that the property was assessed as Residential (RT) where previously it was Farmland (FT).

For more information contact Agricorp at 1-888-247-4999 or contact@agricorp.com.

Methods of Payment:

Your supplementary / omitted tax bills can be paid by the following methods:

• In person by cash, debit or cheque (made to "Township of Mapleton"
• Cheque mailed to PO box 160, Drayton ON N0G1P0
• Online banking using your 19-digit property roll number
• Pre-authorized payment plan - see note below for adjustment

If you are enrolled in a Pre-authorized  Payment Plan, your monthly payment will be adjusted according to the due dates on the bill.

If you are enrolled in the Pre-authorized Installment Plan, your supplemental bill is included in this plan.

If you did not own the property for the entire period you are being billed for, you should contact your lawyer to advise them that you have received these retroactive tax bills. Taxes are levied against the property and not the person. It is the legal responsibility of the current owner to pay the property taxes. 

Past due payment penalties will apply at a rate of 1.25% on the first day after the due date and interest at a rate of 1.25% will be added each month thereafter.
