2024 Final Tax Due Dates

Property Taxes are made up of three main components: the Township of Chatsworth (local taxes),County of Grey taxes, and Education Taxes. Local taxes are used to provide the Township of Chatsworth property owners with a variety of services including: road maintenance, snow removal, emergency services, arenas, planning and development, and much more.

The County and Education taxes are not retained by the Township – they are simply passed along to these levels of government to allow them to provide their services.  Total property taxes are determined by multiplying the Current Value or “Assessment” of your property by the annual Tax Rate for the property type or “Property Class” plus any applicable special charges.

The final 2024 Local, County and Education tax rates for the Residential property class are summarized here:

To estimate your final 2024 taxes, multiply the total rate for your property’s classification by your assessment value, that MPAC (the Municipal Property Assessment Corporation) determines.

The Township of Chatsworth issues two tax bills per year; an interim tax bill and a final tax bill. Each of these is split into two payment installments. The interim tax bill is based on 50% of the prior year’s total tax bill. The interim tax installment payments are due the end of February and April each year. The final tax bill is calculated using the current year’s tax rates set by council. The interim tax bill is then deducted from the final bill calculation, and then the balance is split into two installments. The final tax bill installments are due the end of July and October each year. Non-receipt of your tax bill does not waive any liability for payment of taxes or penalty/interest charged. Arrears are due immediately. Payments are due on the due dates and in the amounts indicated on your tax bill. If taxes are not paid on the due date, a penalty of 1.25% will be charged on the first day of each calendar month until paid in full. The Finance department has no authority to waive penalty or interest for any reason.

  • Their 2016 property value.
  • How we use sales to determine the value of a home.

If there have been changes to your property assessment due to new construction or property improvements in the current year or the previous two years, you will receive a Supplementary Tax Notice. It will be based on the supplementary or omitted assessment placed on your property by MPAC. The Supplemental Bill is in addition to what may have been previously billed on the property, even if the amounts are not yet due.


The Municipal Property Assessment Corporation (MPAC) is a Provincial Crown Corporation responsible for conducting Ontario property assessments.

Contact MPAC:

  • Call: 1-866-296-MPAC (6722)
  • Fax: 1-866-297-6703
  • Write: PO Box 9808, Toronto ON, M1S 5T9

MPAC is legislatively responsible for updating assessments when changes occur to properties and will send the property owner a Property Assessment Notice or Minutes of Settlement advising of the change. MPAC forwards the Assessment changes to the Municipality for processing the adjustment required which is calculated by a SUPPLEMENTARY TAX BILL and forwarded to the property owner.

You may receive a SUPPLEMENTARY TAX BILL to adjust the taxes when there is:

  • Changes to property’s assessment resulting from a Request for Reconsideration or Assessment Review Board Decision.
    Request Forms for Residential and Non-Residential Properties
  • Change to property value increase/decrease (i.e. addition, new construction or demolition of old structure).
  • Change in Tax Class (classification) of the property.

If your new home or addition is not assessed during the year that it was occupied or completed, or substantially complete, the Assessment Act allows MPAC to assess any new house or addition (that has been omitted from the assessment roll) for the current and any part or all of the two previous years and you will be responsible for the taxes from the effective date.

All properties in Ontario are assessed by MPAC every four years.

To establish your property’s assessed value, MPAC analyzes the property sales in your area. These sales provide the basis for assessed values. MPAC continually collects information about properties to ensure that similar property types are valued consistently within the market area. This method is called Current Value Assessment. It is used by most assessment jurisdictions in Canada and around the world.

For questions about your assessment, please contact MPAC at 1-866-296-6722 or visit

The December payment will have to be adjusted to include any remaining balance or credit. Payment withdrawal date will be on the 28th of each month.

If you own more than one property, a separate authorization is required for each property.

If you are expecting a value change such as building an addition, or constructing a new home, a separate Supplemental Billing will be generated. Your Monthly Plan amounts may be adjusted to include the additional taxation. All tax amounts billed in the current year have to be paid by December. Please call if you have any questions regarding Supplemental Billings.

If a payment is not met for any reason, you will be subject to a finance charge and applicable penalties.  If any two payments are not met, your enrollment in the preauthorized payment plan will be terminated.  To be removed from the plan, or if banking information changes, notify the Township of Chatsworth Tax Department in writing at least 30 days before the next payment is due.
