Not sure how that works. There are so many issues to contend with. I know while duck hunting you cannot shoot from a moving boat and you have to use steel shot. Yet on our island, which is on the same lake, we can shoot trap off our shore and use lead. I think you need to look into the firearms act side of things, not hunting.
On a side note, not really related to this, my uncle was once charged by the MNR for shooting from a moving vehicle. What happened was that he shot a duck, left his blind to retrieve it, but it was still alive. He shot it again while his hunting partner was driving the boat and the MNR saw this and charged him. He took it to court and won. His argument was that he was "making every reasonable effort to retrieve downed game." Which he was and the court accepted that since a lot of duck hunters know that a wounded duck will dive under water to try and stay alive.
