I can tell you that we—NORAD here—monitored the flight path of the balloon for most of its flight path over Canada. As has been discussed in the media, there were some radar gaps throughout some of its flight path. As far as the actual oversight location is concerned, the high-altitude surveillance balloon of the PRC came in proximity to some of the Canadian bases, but I cannot speak of the actual response of those Canadian bases. If you allow, I'll turn to General Prévost to potentially address that aspect of the question.
