Payments for Taxes and Water at Banks

Effective June 6, 2016 banks will no longer process water and tax bill payments using paper based processes.  You can continue to make water and tax payments through electronic bill  payment options, but they will no longer accept bill payments that require a paper stub.  Sorry for the inconvenience, however, this is a bank policy change and not a Township of St. Clair policy change.  Options for water and tax payments are in person, mail, on-line banking, telephone banking and pre-authorized payments.  Preauthorized forms can be found below.

Preauthorized Tax Payments

Taxpayers who wish to enroll in the Pre-authorized Tax Payment plan can complete and return the pre-authorized form available by clicking here or can call the Tax Office to request one. If your payment is late, a penalty charge of 1.25% will be added the day following the due date and the first day of each month thereafter.

If you would like to cancel or make changes to previously arranged pre-authorized payments, please click here for a change or cancellation form.

Property Assessment Notices

Property owners are encouraged to visit to confirm their property details and compare their property with others in their neighbourhood. Login information is included with every Notice mailed.

Enquiries about Property Assessment Notices and assessment matters in general may be directed to the Customer Contact Centre at 1 866 296-MPAC (6722) or 1 877 889-6722 (TTY). Property taxpayers may also visit or their local MPAC office. The hours and address for the local office are included on every Notice mailed.

Tax Rates:

Your interim tax bill is calculated at one-half (1/2) of the previous years taxes, adjusted for any changes in assessment during the previous year (annualizing any mid-year changes). Your final tax bill is calculated out as follows: 2007 assessment x 2007 tax rates less interim levy. You should have received a notice from the Municipal Property Assessment Corporation (MPAC) in late 2006 only if your assessment changed from 2006. Please call MPAC directly if you have concerns about incorrect assessments (click here for further information).

Vacancy Rebates (Commercial or Industrial Properties):

Vacancy rebates are available for commercial or industrial properties that provide a tax rebate of 30% or 35% respectively for properties that are unused at least 90 consecutive days (see detailed rules below included in the Ministry of Finance bulletin). The application must be submitted by February 28th of the year following the taxation year to which the application relates.

Tax Capping Parameters:

Tax capping is a mandated Province wide (calculated at the County level) method of ensuring commercial, industrial, and multi-residential properties do not face tax increases greater than 10% of the previous years taxes. This is paid for by increasing the taxes of properties with decreasing assessment in the same tax class. Feel free to call our office if you require further information.
