There's a lot in that question, Mr. Chair. I'll do my best, and I will then turn to my colleague, the vice chief, to see if she wishes to add anything.
First and foremost, an ongoing presence is important. There were exercises with allies up there in recent weeks, but even sailing ships up in the north is important as well.
In terms of the specific question around future proposals, it is in the mandate letter to the minister to bring forward a proposal to modernize NORAD and the continental defence. I can't comment much further on that today, but that is in the mandate letter.
In terms of technology, it's one of those things. There's technology now, but it's also an ever-evolving field and the department does indeed have a research program to monitor the latest and greatest and ensure that industry is engaged, but I think it's premature to comment on what type of technology would be best suited to the risk.
Maybe I'll pause there and see if the vice chief wishes to add anything.
