Yes, it's just one game, but Michigan crushed its Canadian exhibition opponent, Western Ontario, 10-1, while Ohio State lost their's, Ryerson, 4-7. It appears Ryerson is one of the better Canadian teams, while Western Ontario isn't.
Michigan's first two regular season opponents, Clarkson and Saint Lawrence tied and lost to Canadian teams, respectively, so even considering the parity of hockey and they're road games, especially since neither team has been particularly good in recent years (I still don't get why they're scheduled in the first place).
