i have been on many canoe trips to Canada and the Bdub,48. I have been bluff charged by a mama moose, had a fisher walk with me on a no name lake portage, I have had to walk around cubs while mama watched. We have had bears walk through our camp. Not once did they ever act like they were anything other than curious. The one that his nose up against the tent and gave a big sniff got his nose punched by my wife. We are very careful with food handling and scent, but some bears hear and see people and come to check things out. Too often people have left scraps for them or have been careless with food and have conditioned the bears. The ones to not trust are the belligerent old males that creep around like cats, hiding in the brush. Further north where these males have never seen or smelled humans they can be a greater threat. I did worry about my canoe tripping expert companion, a protective cocker spaniel that knew more about canoe tripping the most canoe trippers. When he came on bears he would growl, but never chase, he would just let me know that there was a really big dog over there.
