Caufield made it 2-0 at 15:03, shooting over Ullmark’s right shoulder from the left circle off a return pass from Mike Matheson.
Alex Newhook pushed it to 3-0 at 3:50 of the third period with a wrist shot from the slot off a pass from Hutson.
Stutzle cut it to 3-1 at 5:30 with a snap shot from the bottom of the left circle.
Caufield made it 4-1 at 7:43, jamming in a rebound in the crease after Ullmark made the initial save on Nick Suzuki’s breakaway attempt.
“They blocked a ton of shots, but we didn’t get those grade-A chances, a lot of them, our line included,” Stutzle said. “I think we’ve got to be better. Obviously, we had high hopes for this game, but you’ve got to give them credit. They played good and we just didn’t play good enough.”
NOTES: Montembeault had his season-opening shutout streak end at 105:30. His longest previous shutout streak at any point of the season was 90:00 from Jan. 14-15, 2023. … Caufield is the first Canadiens player to score in each of the first three games of the season since Tomas Plekanec in 2014-15.
