Thank you very much. That's a very good question.
Before seeking funding and approval for a new polar class icebreaker, we assessed options, including long-term leasing and long-term contracting. The reality is there isn't anyone to lease from. Worldwide, I believe the last significant build in icebreakers was in the 1980s. The only place where there might be a lease possibility is Russia. They have been leasing some of their old, heavy nuclear icebreakers, which are way too big, expensive, and old. So that's not a consideration.
We're quite confident that the icebreakers we have now—the Louis St. Laurent, the Terry Fox, and our four medium icebreakers—will be able to do the job until we have a new polar class icebreaker. So we looked at other options, but there just isn't a market out there.
As to where one would be placed, when a polar icebreaker arrives--and we're aiming for 2017--the decision will have to be made then, depending on a variety of considerations. If that sort of decision were being made today, it would have to be south of 60, because north of 60 there are no facilities in place for maintenance and other regular work. So the home base would have to be south of 60, as is the case with our current icebreakers. I won't speculate on what the situation might be 10 years from now and what the options might be.
