Here in Southern Ontario its just finding the ducks.I live right on Lake Ontario and the places to hunt are endless but knowing where to go is the trick.
Early season there is always lots of teal,later if you use layout boats and do alittle scouting you will find rafts of bluebills and if its late in the season you can shoot the late mallards and blacks.
We use to do alot of late season hunting for whistlers and bufflehead and we were usually the only hunters around for miles and there was an endless amount of old squaw but we would never shoot these because here they are considerd junk.I know of one outfitter around the Brockville area that you may want to try ,I see them on TV all the time ,,try St. Lawrance Outfitters or check out the lake Erie ,Lake St Clair area ,from what I hear its really good,,,,,,,,Chuck
