I'll ask Mr. Swales to add to my answer. Obviously we have three coasts, and the ability to operate in the west, the east and the north is becoming even more important as we are seeing shipping lanes expand in the north and that sort of thing. Having a shipbuilding environment here in Canada is a reasonable undertaking. At this point in time, the balance of getting ships in a timely way with the economic benefits and with the objective of getting a sustainable shipbuilding economy going is a challenge.
Mr. Swales, would you like to add to that?
