While hunting from a boat, may I start shooting at waterfowl while the motor is still running?
Answer: No. Hunting may only commence once the motor has been turned off and the boat (any boat, canoe or yacht equipped with a motor) has stopped its forward progress as a product of the engine’s propulsion.
I'm still unsure about the 'human-powered' stuff though
Read a little below the above-link, and you have this:
What are the regulations around retrieving migratory game birds and subsequent use of harvested birds?
Answer: The regulations require hunters to have an adequate means of retrieving birds and immediately make every reasonable effort to retrieve a migratory game bird that has been killed or injured, and if it is still alive that they kill it immediately. A power boat may be used to retrieve a crippled, injured or dead migratory game bird. However, you may not shoot at a migratory bird while the boat is in motion. Migratory game birds taken must be then counted toward daily bag and possession limits. Also to be taken into account is that some provinces and territories have laws which require that edible meat of harvested game not be wasted, destroyed, spoiled or abandoned.
