Jake Sanderson had a goal and three assists, and Tim Stutzle had a goal and an assist for the Senators (22-19-6), who had won two in a row.
“Very frustrating,” Sanderson said. “We played a great 56 minutes but you’ve got to play 60 to win, especially against that team with the high offense and the ability to come back in a game.”
Leevi Merilainen made 13 saves in his 10th consecutive start.
“Our team can hang their head, or they can be mad,” Ottawa coach Travis Green said. “I’d rather us be mad. We played a hell of a hockey game tonight, and that happens. I’ve said it a lot, but it does happen, and we’ve got to move on.”
Slafkovsky gave the Canadiens a 1–0 lead on the power play at 3:06 of the first period. Playing the puck behind the net, Suzuki fed Caufield, who quickly slid it to Slafkovsky in the left circle for a one-timer to the glove side.
Montreal’s Zachary Bolduc had a goal overturned at 11:30 after Ottawa challenged for offside, but Caufield made it 2-0 at 17:50 with the Canadiens back on the power play. After Suzuki won a puck battle against Claude Giroux near the left boards, he fed Caufield, who moved into the left circle and beat Merilainen with a wrist shot through the five-hole.
Brady Tkachuk scored the first of Ottawa’s four second-period goals, cutting it to 2-1 at 42 seconds during a 5-on-3 power play. Giroux got to the rebound of Sanderson’s shot in front of the net and passed to Tkachuk for a wrist shot in the left circle.
“I think they were executing at a much higher level, especially in the second period,” Montreal coach Martin St. Louis said. “They caught us out there for a long time. I think fatigue builds up.”
Stutzle tied it 2-2 at 3:07 of the second, skating along the goal line down the left side and lifting a shot between his legs that went inside the near post.
“I don’t even know what to say,” Stutzle said. “Didn’t give them a whole lot. Felt like we played a really good game, and if you score five, you should be able to win.”
