That's a complicated question.
International shipping is governed by what's termed the ISPS--international ship and port facility security--code or regulations, which is governed by the IMO. Of course, Canada is a participant, so we have the same security protocols in place. This is to protect the ship but also to protect the port from people or harmful substances or things of this nature.
The issue with the Arctic in terms of an unwanted presence is that there is very limited capability or facilities in the Arctic. Let's take an example of a vessel that wants to enter Canada's Arctic. There are very few places, if any, where it can actually stop and be vetted before it enters. Under the procedures and protocols of this ISPS, vessels have to maintain a state of security and then pass along crew information and information on who they are and where they are coming from. I don't know where they would be going or what they would be doing, but there is no presence, no dedicated area or facilities or places, apart from an agreed-upon place, such as Churchill, Manitoba. If I had a ship coming over, between me and Transport Canada, or the agencies that govern that, we would say that when the vessel stops in this particular place, we'll dedicate the local member of the RCMP to come on board, as part of our security procedure, to look over the documentation, such as who's on board and things of that nature. That's really it. Where they decide to do this, if at all, is usually between the ship operator and the government.
