Thank you, sir, for your work.
One of the things that I think the committee has had trouble determining—I know I have—is who owns this issue. It seems like the airport authorities say, “We only land the planes that want to land here.” Nav Canada says, “Our job is to make sure they land safely.” It seems like Transport Canada has kind of hived off responsibility to Nav Canada.
Suppose we were to come forward with certain recommendations. Let's just pick one out of the air, one that has been suggested by numerous witnesses: banning night flights, for example. In your study of this issue, in your work, who do you see would actually have the ability or the authority to do that?
