Maybe I will start, Mr. Chair. The vice-chief may have things to add.
I think we've already touched on the importance of the Arctic offshore patrol ships and the voyages that they've already taken. There's more to come on that front, so presence is important.
The other one I would flag is the ongoing maintenance of the North Warning System. That work is important. We've also discussed that there are ongoing discussions about NORAD and continental defence modernizations. There's more to follow on that as well, but it's premature to say anything beyond that at this stage.
Vice-chief, did you have anything to add?
