I'd like to make a point. The fines are considered surcharges. Canada Post has been going through updating their invoices and their financial system, and they do not have a process for reversing surcharges. If there is a mistake—and generally these are often mistakes on the Canada Post end so there's an issue at induction—and the employee believes that something has been done wrong, they automatically fine the mailer. There is no process at Canada Post for reversing those fines. They do not have an accounting process to do that.
