If you want to hunt Canada check out Spirit Creek Outfitters, I was told that they take more big bears in the spring hunt. hunts are over bait. I saw my first bear within 15 minutes of being dropped off and continued to see bear everyday I hunted.
If you think about Montana, I would consider Montana Mountain / Elk Creek Outfitting (Heron, MT). They operate in the far west of the state. They have some beautiful color phases of black bears out there. I have hunted elk and deer with them before. Some of the references I spoke with sang the praises of their bear hunts. Brad is a hell of a guide, and the whole operation is top-notch. I'll be making it back out there for bear at some point.
