most of my Canadian deer hunts have been in Alberta and BC, I have hunted a bunch of area's and places over the yrs, in Canada besides them, but that's where I have done most of my hunts, in Canada!
so no real one spot or area for me!

for me, I always enjoyed seeing different parts of states or provinces , so tried to hunt different area's rather than keep returning to same area's over and over, thought I have hunted a few spots back to back yrs!

I have also known a bunch of folks from all over Canada, that have had me up in off season to visit and or back to hunt(some times just tag along, with them hunting ), also used to snowmobile trial ride a lot in Canada too yrs ago, mostly on the eastern side of things(Ontario, Quebec, New Brunswick)

one thing I do seem to notice however is, northern Canada, or Canada in general (same can be said here in the states) as it seems most area's just don't seem to have the COLD temps and winters they used too, I recall hunting back in the late 80's early 90's and temps would be in the minus 40 and lower at times and always had snow, in northern AB< BC, SASK> , they were known for some super low temps when deer hunting , taught you for sure how to dress to stay warm, or you were in for a long cold day !

but the last decade or more, snow and cold doesn't seem as reliable as it used to be,
not sure that makes hunting better or worse LOL

as them cold temps used to make deer have to feed more, but warmer temps make sitting all day easier , so double edge sword I guess !!
