Paul Cotter and William Carrier scored, and Adin Hill made 37 saves for Vegas (9-0-1).
“We got 19 out of 20 points, so to me, that’s pretty good. We’re not going to push that aside or overlook it,” Vegas coach Bruce Cassidy said. “We haven’t always looked our best, and I’ll be the first to say that. Tonight included. But it’s not easy to win.
“A lot of different guys scoring. Tonight, it’s Cotter and Carrier and we get points. It’s not relying on the top guys. Our top guys are probably struggling a bit to get points to the table. We’ll need that eventually.”
Sean Monahan and Nick Suzuki scored, and Sam Montembeault made 23 saves for Montreal (5-2-2), which is 4-1-1 in its past six games.
“We knew we were playing well. It just seemed like we were swimming against currents sometimes,” Canadiens coach Martin St. Louis said. “In the past, we would have lost ourselves in that emotional challenge. Tonight, we talked about it. Tonight, we had to regulate."
