For a field hunt I would look at the Peace Country of Alberta. It is pretty well the staging ground for huge numbers of waterfowl.
I tend to hunt smaller wetlands here in the South Country. A couple dozen dekes and my waders. Take the canoe along in case the slough is deeper than my chest waders. (I don't have a bird dog)
Season opened in the Peace on Sept 1st. Today was the opener in the South but I missed it due to a kid in the hospital. We had a snow storm in Calgary but by the time we got back to Redcliff it was a rain event. I plan to get out early Wednesday to a secret little slough.
