Mr. Speaker, the role of Norad is to detect and warn our countries of incoming or variations in man-made vehicles or missiles. This agreement has nothing to do with the proliferation of nuclear arms. This is a protection method so that we can see if something is coming in, if something poses a threat to our airspace, and thus provide our countries with a warning in advance.
