Yes, I didn't see any bears in Alaska or the Yukon, but I saw 21 of them in British Columbia, mostly along the Casiar highway
I carried a can of bear spray to be safe, but I didn't have any problems
I'd just have my hands around and yell then slowly roll past them
And of course when your camping you have to hang all your food and anything that gives off a scent (toothpaste, deodorant, cookware, etc.) away from your camp unless you want a bear to come peeking into your tent at night
