Guss, you wont be able to do it completely on your own in Ontario. If you are a non-resident, you will have to go through an outfitter. I have hunted moose 3 times in Ontario. All 3 times we should have had filled tags, but mistakes at the last minute put the odds in the moose's favor. Its not impossible to do it on your own. I have never used a guide, but do have to go through an outfitter. I would say do your homework, and find a good outfitter in a decent area, and give it a whirl. Make sure you find some instructional tapes that teach you how to call. That will help you alot.
