Frequently asked questions about the online service
The secure online platform allows you to view the school tax bill for your property or properties for the current year, as well as a multi-year history in most cases. You can also check your statement of account to track your payment history. Click on the “bill” icon to access your school tax bills, or on the “account statement” icon to view your statement.

The platform also allows you to opt for online billing from your profile. By choosing this option, you will receive an email each year, around July 2, notifying you that your school tax bill for the current year is available on the platform.

No, payment cannot be made through the platform. Payment instructions are provided on your school tax bill or on the School tax payment page. In short, you are asked to pay your bill through your financial institution (at the ATM, at the counter, or online) or by sending us a cheque by mail.
