Price blanked the Maple Leafs on three power plays and was especially sharp in the second period, when he turned aside 13 shots to preserve a one-goal lead.

Both teams paid tribute before the game to Pat Burns, who died of cancer Friday. Burns, in his first year as an NHL coach, guided the Habs to the 1989 Stanley Cup Finals and also coached the Maple Leafs during his career.
