They extended their lead to 2-0 in the second period when Rich Peverley blew a slapshot past Leafs goalie James Reimer, quieting the raucous home crowd.
Defenseman Peter Harrold came closest to pulling one back for the home side with 4:09 left in the game, but his slapshot rattled Lundqvist's left-hand post and bounced harmlessly out.
