The skinny: The Canadiens scored two power-play goals in a 2:51 span late in the second period and held on for a 4-2 win over the New York Islanders Sunday night at the Bell Centre. The victory snapped a four-game winless streak for the Canadiens. Special teams mismatch: The Canadiens power play, which went into the game ranked No. 3 in the NHL, took advantage of an Islanders penalty-killing unit that is the league’s worst. Lars Eller snapped a 1-1 tie when he beat Montreal native Kevin Poulin from the faceoff circle at 16:14 of the second period. That ended a 12-game goal drought for Eller. Michaël Bournival made it 3-1 when he redirected Raphael Diaz’s shot from the blue line at 19:04. The Canadiens went 2-for-5 on the power play. Kids’ night out: The line of Eller, Brendan Gallagher and Alex Galchenyuk continued to be the most dangerous trio for the Canadiens. Galchenyuk and Eller had a goal and two assists each while Gallagher had a goal and an assist. Gallagher opened the scoring early in the second period with his team-leading eighth goal of the season, and Galchenyuk had an insurance goal midway through the third period. PK streak ends: When Pierre-Marc Bouchard scored a power-play goal at 7:23 of the second period, it was the first goal against the Montreal penalty-killing unit since San Jose’s Logan Couture scored on Oct. 26. The Canadiens had successfully killed off 21 penalties before Bouchard connected on a shot from the point. Brock Nelson added another power-play goal in the third period as the Islanders went 2-for-4 with the extra man.
