To obtain a pilot licence, the individual has to be highly trained; they have to know just a stretch of a river, maybe 60 miles of it, inside and out, without charts and without the aid of electronic equipment. That licensed pilot becomes our employee, our expert. The navigation officers who work for the Canadian fleet certainly have knowledge of the region they are sailing, but not as detailed as our pilot.
When a Canadian ship is trading in the Great Lakes, it has its own crew. The captain knows his or her own ship, whereas an employee pilot will be boarding a foreign ship that is not constructed for the Great Lakes. It's constructed for the high seas, and it has a crew that has grade two or grade three English and no idea where they're going.
So there's different interaction with a marine pilot and an officer of a Canadian ship. These are two different sets of skills to have.
