There are plenty of opportunities for shots at bruisers up here during the bow season and many outfitters specialize for bow hunters. If you look for one in the Alberta Bowzone, the area around Edmonton that is bowhunting only, you should find some good opportunities.
I know that in Manitoba, the only way non-residents can hunt some of the best areas (agricultural region) is with a bow and I think the same is true for Saskatchewan. Otherwise, you're further north in the "big bush" where there are still lots of chances but the deer are harder to pattern becasue there is less agriculture.
It's still a great time of year to hunt deer in Canada, they are easily patterned and relativley unspooked by hunting pressure.
Just find an outfitter that knows what a bowhunter needs and you'll still have a great hunt.
