There's a question there that is multi-part.
In 1972, when the Pilotage Act came into force, Parliament recognized that there were Canadian sailors going up and down the Great Lakes piloting their own vessels and decided that these people would get special treatment. They were already doing the job. So Parliament put in the Pilotage Act a transition period that would allow these people to come to the authority and receive a pilotage certificate. That never happened. There were always numerous reasons for its not happening.
