Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).

At the time of publication, ISO/IEC 18056:2004 is available from ISO and IEC in English only. CSA will publish the French version when it becomes available from ISO and IEC.
