I would like to make a minor note about the disclosure of occupations within PCO.
In 2004 I did a little study of a request that had been sent to PCO for consultation on security grounds. After September 11, guidance was given to federal government departments that certain requests would be pulled out for review by PCO on security grounds, given the new circumstances. PCO later told me that it had undertaken 184 security-related access consultations between September 2001 and March 2003. My calculation was that three-quarters of those security-related consultations by PCO pertained to requests submitted by journalists, members of Parliament, or representatives of political parties. It was straightforward to make that calculation because PCO's own list of referrals included those categories on the list.
