First, to answer the question you asked me earlier, I would point out that there is an international UN forum on aviation issues. It is the International Civil Aviation Organization. That's the appropriate forum.
Furthermore, the names of known individuals who have been detained and tortured on the basis of false information have already been mentioned: Messrs. Arar, Almalki, Abou El Maati and Nureddin. Many Canadians originally from Middle Eastern countries are rightly afraid to go through the United States. They might feel safe taking a direct flight from Canada to Europe to get to the Middle East. However, if information about them were forwarded to American authorities, those authorities might let them travel but might provide information harmful to those individuals to countries where there is no rule of law, to Syria, for example. The consequences for those individuals could be very serious. In Canada, that kind of system would therefore constitute a threat to innocent people such as those I just mentioned.
