Keep playing until there's a winner. For this level of the sport, so be it if the game runs an extra hour.

If Canada had won by shoot-out, I wouldn't have considered it an olympic-calibre win. I would have simply considered that they had to shut the lights off and at the end of the day someone had to get the medal. Especially since the US team got to the finals undefeated and with more points than the Canadian team. It seriously devalues the game.
