Canadiens 4, Senators 1

OTTAWA - Jaroslav Halak made 45 saves and Tomas Plekanec had three assists as the Montreal Canadiens extended their winning streak to three with a 4-1 win over the Ottawa Senators on Tuesday night.

Mike Cammalleri, Marc-Andre Bergeron and Andrei Kostitsyn all scored for the second night in a row and Scott Gomez added an empty-net goal.

Cammalleri scored for a third straight game late in the first for Montreal, which beat Philadelphia 3-1 on Monday night despite being held to 13 shots.

Mike Fisher scored his 13th goal of the season early in the second for Ottawa, which had a five-game home winning streak snapped despite a 46-27 shots advantage.

Brian Elliott stopped 23 shots in his ninth straight start for the Senators, who earned a 4-3 shootout win at Anaheim on Sunday to wrap up a 1-3-1 road trip.

Plekanec, who assisted on Cammalleri's goal, helped set up Bergeron's second power-play goal in two games midway through the second period as Montreal regained a 2-1 lead.

The Czech centre got his third point on Kostitsyn's fourth goal during a power play with 2:18 remaining in the game. Gomez scored his fourth goal into an empty net with 1:05 left.

Canadiens right winger Ryan White played four shifts for a total of 3:13 in the first before he was removed from the game because he was ineligible. Montreal recalled White from Hamilton of the AHL earlier in the day but neglected to inform the NHL about the roster move.

Halak made his second start in four games, improving to 6-4. The Slovak goalie came up with a number of big stops as Ottawa held a 13-5 edge in shots in the opening period.

Limited to one shot in the first period on Monday, the Canadiens struggled to get anything through to Elliott before Plekanec teamed up with Cammalleri on a 2-on-1 late in the period.

Checked by Ottawa defenceman Anton Volchenkov, Plekanec fed a pass to Cammalleri, who fired the puck into the left side of the net for his fifth goal in three games 18:32 into the period.

Fisher tied it 1:46 into the second when he was left alone in the slot to put Milan Michalek's rebound past Halak.

White was called up because defenceman Paul Mara was unable to make the trip after he left Monday's game because of an upper body injury.

Montreal lost another blueliner in the first when Jaroslav Spacek was struck on the right knee by former Canadiens winger Alex Kovalev's shot. Spacek left the game and didn't return.

NOTES: The Senators, 6-0-1 at home in November, began a stretch in which they will play 10 of 15 games in Ottawa, including Saturday's visit by the Carolina Hurricanes at Scotiabank Place (7 p.m., CBC, Team 1200) ... The Canadiens have allowed just one goal in each of their last three wins after giving up a total of 15 during a 0-3-1 skid that preceded their current streak ...
