Why would you be looking for a whitetail hunt in Quebec? Unless you're looking to go to Anticosti island, you aren't going to find anything here that you can't find in NH. In fact, I'd say the hunting would be better in NH, especially north of Pittsburg. If you are set on coming here, try looking here:

I think there is a searchable interface that allows you to narrow your search down to species and area in Quebec.

Good luck.
