Reinhart tied it 1-1 at 13:16. He picked up the puck following a turnover deep in the right corner, went to the net and beat Montembeault with a backhand.
Montreal’s second power-play goal made it 2-1 at 11:27 of the second period. Slafkovsky’s cross-crease pass clipped the skate of Jones before the puck went in off Bobrovsky’s stick.
“We had a good day off [Saturday], everyone rested, and we were ready to get the two points,” Slafkovsky said. “It was a bounce forward from last week, and everyone fought out there. We have to keep going. It’s not about one win. We have nine left, and we have to keep grabbing points.”
Jones tied it 2-2 at 16:25, scoring from above the right circle by one-timing a Barkov pass.
Suzuki scored at 2:02 of the third to give the Canadiens their third lead of the game at 3-2. He took a cross-ice pass from Hutson and scored with a one-timer from low in the left circle.
“The two power-play goals are the biggest piece,” Florida coach Paul Maurice said. “I think we had [23 shots] blocked tonight, missed the net [on] another [21]. So, we let a lot of offense die in that game.”
Brendan Gallagher scored into an empty net at 18:16 for the 4-2 final.
