Let me intrude for a moment.
The air carriers collect the information, and I agree with you that they, like a whole host of companies, use the data they collect for their marketing purposes, but the point we're talking about is that at least in Canada the data they are collecting can only be shared with anybody else provided they get the consent of whoever is providing it.
The range of information that an air carrier is going to generate from an individual passenger that is relevant to the air carrier's purposes is presumably legion. It goes right from how big they want to make their aircraft to the range of the seat, etc. The issue we're talking about here is that it's the air carrier that actually collects the API—they're required to by statute—and that it is therefore they who have to share it with the Americans, but we have to be careful. Some information that air carriers will be using for their own purposes is protected under Canadian law by PIPEDA. The question is what exemptions we are going to grant for that information, and that is an excruciatingly difficult question. I completely agree with that.
