Yes, of course, and of course we've had discussions.
As you quite correctly pointed out, national defence is responsible for that. I know the Minister of Defence has, within her mandate provided by the Prime Minister, a responsibility for the renewal of NORAD. You're right that the system as it was designed many years ago was to deal primarily with airplane incursion into Canadian airspace. Now there is an evolving series of threats, including, obviously, hypersonic missiles. That renewal is part of that responsibility.
I'm aware of that work, but questions with respect to its progress are better put to the Minister of Defence.
