Lars Eller doused the tension with an empty-netter.
Price made 35 saves for his 38th win, tying his career best.
The second period wasn’t a minute old when Tomas Plekanec completed a nifty three-way passing play with Alex Galchenyuk and P.A. parenteau to get the Canadiens on the board.
Max Pacioretty’s shorthanded goal, scored off a bad play by Islanders goaltender Michal Neuvirth, made it the dread 2-0.
Matt Martin had a chance to get the Islanders back into it but muffed his shot and was robbed by Carey Price.
Torrey Mitchell was injured on a first-period faceoff and did not return.
