Supplementary Tax Bills

Supplementary tax bills are usually issued three times per year (spring, summer and fall) and are in addition to any other tax bills that may have been issued.

Supplementary tax bills are sent out as a result of a change in your property during the taxation year. These changes can include, but are not limited to: new residential homes, new commercial, residential or multi-residential units, changes in tax classes, additions or renovations to buildings and previously exempt properties that become taxable.

The Supplementary tax bills are on 8 ½ x 14” blue paper and are due at different times throughout the year rather than the regular March, May, July and September due dates. The bills themselves also indicate what time period they are for and the reason for the change. These bills follow the Supplementary Assessment Notice that you would have received from MPAC prior to the issuance of the tax bills. 

The Assessment office is responsible for assessing the properties and forwarding the information to the City for billing. Sometimes these bills can span more than one year depending on when the assessment office is able to visit your property and the supplementary assessment cycle.

Supplementary tax bills do not include any property tax arrears or credits that may be on account. 

If you are on the City’s Monthly Pre-authorized Tax Payment Plans, you must contact the Tax Office if you would like your payments be increased to include the additional taxes owing.

If your mortgage company is responsible for paying your taxes you will need to forward the Supplementary Tax bill to them for payment.

If the property is sold before the supplementary tax bill is issued, the bill will be sent to the current owner of record and it will be up to the solicitor’s involved in the original transaction to calculate each owner’s liability.

If you have questions with regard to your Supplementary Tax bill, please contact the Tax Office at 705-742-7777 x1865.

If you have questions with regard to your Supplementary Assessment Notice, please contact MPAC (Municipal Property Assessment Corporation) at 1-866-296-6722.
