Welcome to Manitoba!
I haven’t pursued any bears myself yet but I can refer you to a guide. Best part: he’s a trad bowhunter! Darren Shipp owns Wild North Taxidermy & has guided with several outfitters in Manitoba & Ontario. I can’t speak for him of course, but he’ll probably be happy to point you in the right direction if not set something up himself. His contact info is at: http://www.wildnorthtaxidermy.com
I hope this helps.
PS: (if you don’t mind saying) where are you coming here from?
