Of course the program has evolved as we have gone along. The basic direction was there in the Public Safety Act. The Public Safety Act, section 4.81, gives the Minister of Transport—that's why it's Transport and not the Ministry of Public Safety, that was the decision of the day—the authority to specify individuals who pose a threat to aviation security.
It's built on that basis, but as we've evolved we have criteria that are public, we have a reconsideration office, and we have the 7/24 office. We've done all these things to try to keep the program as efficient and effective as possible.
