The Organization?s customer agreements require customers to keep their contact details up to date, including their mailing address. From time to time, mail sent by the Organization to customers at their address on file is returned to sender. On the basis that such customers have not updated their mailing address, the Organization will place a return mail flag on their accounts directing that mail not be sent to their address until such time as their address has been updated (?return mail flag?). Between February and March 2020, due to a system error, the Organization sent 2019 tax slips to the holders of accounts with return mail flags on them (sent to the last address noted on the customer account). An individual, who was not a customer, informed the Organization that they received mail for a customer with the Organization.
