A notable shortcoming of the Canadian implementation of the do-not-call list is that the list of numbers is given to telemarketers in plain text, in the form of a simple spreadsheet or CSV file without any protection or traceability. Technologies for securing personal data are readily available, as shown by Australia's Do Not Call Register, which "is a secure database where you can list your numbers to avoid receiving unsolicited telemarketing calls and marketing faxes." In contrast to the CRTC's uncontrolled distribution of telephone number lists, the Australian system consists of a "List Washing Service", precisely as proposed by the minority opinion which was disregarded by the CRTC.
