If I could add, I think the threats facing the Arctic, if we call them threats, are not of your typical defence sort. They are more about safety and security.
That's a whole other conversation about what we do with the Canadian Coast Guard. With the fact that they are only a safety organization, should that be changing to a security mandate as well, and do we have enough ships and icebreakers? However, that's a different conversation from NORAD and its aerial mandate.
