Certainly, as we mentioned before, CADs in North Bay have a pretty good visual capability throughout the majority of Canada. The Arctic's obviously very difficult, though. There's not a lot of infrastructure up there, and certainly not a lot of civilian radars up there either. This is where the north warning system becomes very, very important. That said, it is getting old and will need to be replaced at some point. We're looking at that through the NORAD aspect right now, so Admiral Gortney, who is the four-star commander of NORAD down in Colorado Springs, has tasked NORAD to specifically look at this to see what future technologies we would need, to best provide us with early surveillance of any enemy who might want to impact North America.
We're looking at it. We don't have the details yet. The north warning system is there for a period to come, but it's certainly prudent planning to do so.
