The Township of Stone Mills would like to advise residents of an error on the 2026 final tax bills that are scheduled to be mailed on Monday, June 22, 2026.

Due to a printing error, all tax bills indicate that the account is enrolled in preauthorized payments. Please note that this statement does not apply to all property owners.

Only property tax accounts that are currently enrolled in the Township’s preauthorized payment program will be subject to automatic withdrawals. If you are not enrolled in the program, your tax bill must be paid using one of the Township’s regular payment methods by the applicable due dates shown on your bill.

For those who are interested in setting up a Due Date or Monthly Pre-Authorized Payment Plan for payment of Property Taxes, please visit our website www.stonemills.com for more information.”

We apologize for any confusion this error may cause and appreciate your understanding.

If you have questions about your tax account or whether you are enrolled in the preauthorized payment program, please contact the Township office at 613-378-2475 or email taxes@stonemills.com.
