I am 5'11 tall, 210 lb's. I wear a size large Marmout jacket. I read the Canada Goose Snow Mantra and Expedition run big, would a medium fit me?
Yeah, I think a medium should fit you well. These do run pretty big so sticking with a large might be a bit much. Also, a little further down there is a guy who answered that he is 5' 11" 180 lbs and he wears this jacket in small and wouldn't want to size up.
