I can start, Madam Chair, and see if my colleagues wish to add anything.
It is a group team sport in this area, in that it is about all domain awareness. You need to keep your eye on the air and sea as well as land.
As we look to fill in the gaps that the Auditor General has identified in terms of awareness, you have to think across multiple departments. Transport Canada has already spoken to what they do. We do have ship patrols in the area when the season is appropriate. We also have our own air, but there's also the existing North Warning System and its upgrade, as well as the eventual replacement for NORAD modernization. That is all about the complete picture.
What I would flag, which is of interest to me, is that where the ships are of a large size and are complying with the law and are self-identifying, that's not a gap. You have smaller ships that are not required to use the identification system, and it's with our partner departments that we piece together that information to try to build the complete picture. We have mentioned numerous tools. I didn't mention satellites as well, which have already been flagged in terms of a tool.
It's that complete set. The Auditor General has flagged some gaps. We are discussing our plans to fill in those gaps as a group, but that's really the core of it.
I'm looking to my colleagues to see if they wish to add anything.
