The responsibility for SAR actually is kind of coordinated through an organization--ICAO. We are a member of that organization. Basically, all ICAO members agree on search and rescue boundaries. Those are not sovereign boundaries; those are totally different. So in the case of Canada, it's very clear: it's the American border and the North Pole, but on both coasts it actually extends beyond Vancouver Island for 1,100 kilometres and on the east coast it goes out to sea for 1,600 kilometres.
Basically, what that says is that in those defined boxes Canada has agreed to take the search and rescue responsibility. So if you have a vessel that's sailing across to England and it's in distress 300 or 400 miles from Halifax, it's our responsibility. Now, I think it's important to point out that if you're a Canadian registered ship and you're off the coast of Bermuda--I'm not sure if it's Bermuda, probably the U.S. or whoever owns that piece--it's an international agreement that your national flag doesn't matter. In SAR, it's humanitarian. We have this responsibility and we execute that responsibility.
