Thank you for your answer, but I don't think I understand how Transport Canada determines [Technical difficulty—Editor].
If I take off in a plane, there's no way for NAV CANADA to know that, so I assume there are other authorities to which that information has to be declared in advance—in this case, Transport Canada.
Is that how it works?
How was the pilot of the aircraft able to declare that the flight was for humanitarian reasons and continue on their way?
