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 last 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 the Flyers, 3-1, on Monday despite being held to 13 shots.

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

Canadiens right winger Ryan White played four shifts for a total of 3 minutes, 13 seconds 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 in the first as Ottawa held a 13-5 edge in shots in the opening period.

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

Limited to one shot in the first period 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 defenseman 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 in.
