Luostarinen put Florida back in front 2-1 at 7:34 of the third period with his second power-play goal. He took a pass from Ekblad and scored with a backhand near the left post.
“Obviously, it is nice being on our power play,” Luostarinen said. “I am trying to take advantage of it.”
Bennett pushed it to 3-1 at 15:26 when he redirected Ekman-Larsson's shot from the left point.
Verhaeghe scored into an empty net at 17:13 for the 4-1 final.
“It is hard to play 60 minutes of good hockey against a good team,” Montreal coach Martin St. Louis said. “They are going to make you struggle sometimes, but I liked that my team tied up going into the third, but you have to be careful of your actions all over the ice.”
NOTES: Canadiens defenseman Mike Matheson had an assist in his 500th NHL game. ... Verhaeghe has six points (three goals, three assists) in his past four games.
