I'll start off.
On the issues of ice highways and the infrastructure, most of the areas where we are operating are in such austere areas--for example, Alert--that what we move in, we move in by air. In some of the other areas where we have port operating logistics sites, a lot of that is also done by air.
One of the things missing in the north is the critical infrastructure to move things around--railways, etc. So to answer your question on the issue of illegal trafficking of drugs and personnel, undoubtedly you could have increased access. It's a vast area. The problem is, when you land there, where do you go? That's the real issue. It is such an austere area...I would be interested. How many on the committee have seen the north? So then you know what I'm talking about when I say it's austere. The colours of grey and white are all you see for a vast part of the year.
To be able to move things in and around that area would be quite a logistical feat. You would have to be able to fly in or support something of that nature, which then gets to the issue of how you know what's in your sky and how you manage it. We do that right now through NORAD, which is our warning, and it gives us the ability to see who's flying in our air space through our early warning sites, which allow us to see if we have aircraft.
Could someone come in through our north? Yes. It would be very difficult, though, and there are easier ways to do it.
