Montreal — Scott Gomez and Marc-Andre Bergeron scored in the first period to give Montreal its first two-goal lead of the season, sending the Canadiens on to a 5-1 win over the Islanders last night.

Max Pacioretty, Mike Cammalleri and Maxim Lapierre also scored for Montreal (4-5), which won in regulation for the first time in 13 games dating to last season.

Jaroslav Halak made 21 saves in his second straight start after helping the Canadiens stop a five-game losing streak Tuesday night with a 2-1 shootout win over Colorado. Halak lost his shutout bid 54 seconds into the third when he misplayed a dump-in behind his net that led directly to Josh Bailey’s short-handed goal.

Bailey drew New York to 3-1 after Bailey easily stripped the puck from Halak and came out front to slide a backhand into the gaping net while the Slovak goalie made a desperate lunge to get back in position.

Martin Biron stopped 38 shots for the Islanders (1-4-3), who claimed their first win of the season one night earlier when John Tavares scored the deciding goal in a 4-3 shootout win over Carolina.

Bergeron and Cammalleri connected on the power play as the Canadiens went 2-for-6, the first time Montreal has scored more than once with the man advantage since a season-opening 4-3 overtime win in Toronto on Oct. 1.

Including the last four games of last season, the Canadiens hadn’t won in regulation since a 6-2 win in Toronto on Apr. 4. Montreal also lost four straight to Boston in the first round of the playoffs.
