Old bear-attack movie

A friend thinks I know everything. I don't. But I'd like to show off. He says he watched an old black-and-white movie on TV, years ago, about a woman in a cabin in Canada who was attacked by a bear. That's all he gave me--no actors, no other details. I have looked online, using many different key words--black and white movies, bear attack, cabin, Canada, etc. but no luck. And it might have been Alaska. Most bear attack movies have men as the hero, so I thought it'd be easier than this.
