This seems like a spectacularly stupid idea very cynically presented:
- Cormorant reputedly tastes awful
- Cormorants are about as much of a challenge to shoot as cardboard ducks in a shooting gallery
- Cormorants do not eat game fish - they are too big
- Cormorants swim/eat with many other birds. Shooting cormorants will disturb all the other birds in the area, causing them to take flight and therefore requiring that all the other birds replace all those calories before continuing their migration, or increasing the mortality rate in migration
- Cormorants nest in colonies with other birds. Shooting cormorants in these colonies will disturb nesting and increase the mortality rate of all the chicks of the other species

As for hunting season, if you proceed with this, at least have the decency of making hunting season the entire year. You do not get to claim that the cormorants are protected for part of the year when the part of the year exempted is that period when all the cormorants have migrated and there aren't any in Ontario.
