Well, I would answer that there could be instances when Canada is involved in a conflict or in an alliance and there is a need for the very high-resolution information you get, and you wouldn't be able to provide it. Or there could be a specific issue that would be applicable to Canada whereby you would need that kind of information and you would not have it. It's not just for sovereignty; flooding can also be seen from a national security perspective.
An example that pops into my mind is being in an alliance in an area of conflict where the U.S. perhaps is not involved, but we are, and we would be required to furnish data and would not be in a position to do that. It's national security, but it's also the defence of Canadian Forces abroad. The five stipulations are national security, defence of Canada, safety of Canadian Forces, Canada's conduct of international relations, and.... So it could be placed here, but Canadian armed forces obviously are not stationed only here.
