Nylander made it 2-0 at 5:39 of the second period when he cut around Lane Hutson in the slot and shot glove side on the power play. Morgan Rielly assisted on the goal for his 400th in the NHL.
Marner pushed it to 3-0 at 8:24 when he took a pass from David Kampf and shot from the top of the goal crease while short-handed with Montembeault out of position.
“I thought Dave was going to one-time it at first to be honest but as soon as I saw him cradle it and put his head up for me, I just tried to jump past my check and get to the net and he made a heck of a play to get it back to me,” Marner said.
The Canadiens cut it to 3-1 at 9:26 when Gallagher swatted a rebound out of the air at the top of the goal crease while on the power play.
“I thought we had a great first period, unlucky bounce, and then the second felt comfortable, and, you know, then we give up a short-handed goal,” Canadiens captain Nick Suzuki said. “Then we had to climb back, I thought we had a good third period, but we just couldn’t score.”
Tavares scored Toronto’s third special teams goal to make it 4-1 at 12:15 on the power play when he put in his own rebound in the slot. It was the fifth straight Toronto power play with a goal.
“Every game is important but no doubt when you are playing teams in your division jockeying for positioning with how the playoff format is set up, [these games] are important so I think it was just the way the schedule was set up this week,” Tavares said. “Good week all around but we know we still have a lot of areas to get better in.”
NOTES: Maple Leafs forward Max Pacioretty fell awkwardly in the slot after taking a hit from Canadiens defenseman Mike Matheson late in the first period and left the game because of a lower-body injury. “We’ll have to see in a day or so what's going on there with him,” Berube said. … The Maple Leafs were without captain Auston Matthews for a third straight game because of an upper-body injury. He skated Saturday for the first time since sustaining the injury. Berube said, “He’s going in the right direction. … He’s feeling better.” Toronto is 38-19-2 without Matthews since he entered the NHL in 2016-17.
