What's at stake:

Unless Canada loses by more than five goals or Finland loses by more than six goals, both teams get a bye to the 2nd round. Firewagon hockey isn't really in the cards.
-> Assuming that neither of scenarios happens (and Norway doesn't pull off their own Miracle On Ice), the loser of this game will play Russia in the 2nd round.

-> If the game ends in regulation, the winner will be the best team of the preliminary round, and will realistically play either the winner of Slovenia-Austria or Slovakia in the 2nd round (with an outside chance of playing Latvia).

If the game doesn't end in regulation, the winner of this game will be the 3rd best team of the preliminary round behind Sweden and US, and will presumably play Switzerland (with an outside chance of meeting Czech).
