Statement of account
To request a statement of account, please complete the form Request for a statement of account. A $20 administration fee (per property) will be charged to your account, and the statement will be emailed to the address indicated on the form.
New property owners
If you are a new property owner and the school tax bill you receive is in the name of the previous owner, this bill belongs to you: Please pay it to avoid interest charges. Change of ownership occurs once an official certificate from your municipality’s assessment department has been received. However, there may be a delay (from a few weeks to a few months) in obtaining or processing information related to the transfer of ownership. We thank you for your patience during the processing of the ownership change.
It is also possible that the school tax bill for your new property was sent to the previous owner. You are still required to pay your bill by the due date. If you are a new homeowner and have not received a school tax bill, please complete the following form to notify us, or contact our customer service at 514 384-5034.
If you have sold your property and receive the school tax bill for the sold property at your new address, you must at your earliest convenience forward the school tax bill to the new owner or email a copy to us at [email protected] indicating that the property has been sold.
Change of mailing address
The property owner or an authorized representative can make this request by email by completing the form: Request for change of mailing address
Power of attorney
The Access to Information Act limits the disclosure of personal information concerning individuals. For anyone other than property owners, there are formalities to complete in order to access accounts.
To grant a power of attorney to a designated person, you must complete the Power of attorney form.
To revoke a power of attorney to a person, you must complete the Revocation of power of attorney form.
Refunds
Refunds due to negative certificates or decisions made by the Tribunal administratif du Québec are issued once the certificates have been received from the municipal evaluators.
Refunds due to overpayments are issued at the owner’s request or following a review of the credit balance. The service charge for issuing a refund for overpayment is $25. Unless an immediate refund is requested by the owner, credit balances of less than $325 are carried forward to the next year.
Payment transfer
A $15 fee will be charged when a school tax payment is made to the wrong account by a homeowner: a statement of account will be issued following the transfer.
Reminder notices and debt recovery
Interest is charged on all late or insufficient instalment payments.
A $25 service charge is added for every returned cheque (NSF, stop payment, frozen account, etc.).
The CGTSIM periodically mails out reminder notices indicating balances due. Interest is calculated as of the due date of each reminder.
In case of non-payment, the CGTSIM may recover its debts in three ways:
- Seizure and sale of personal property
- Sale of property for non-payment of school taxes
- Personal action under common law
