"He made a big save and the bench goes wild," Panthers head coach Paul Maurice said.
Netting his first goal with the Panthers, Givani Smith, acquired from the Red Wings last month, extended the lead even further when he followed up on his own shot, plucked the rebound out of a pile of players in front of the net and fired the puck past Montembeault to make it 4-0 at 16:03.
Matching a franchise record with their fourth power-play goal of the period, Tkachuk capped off the historic middle frame with an exclamation point when he took a pass from Reinhart, walked the puck into the right circle and ripped shot off the far post and in to make it 5-0 at 19:17.
The goal also marked Florida's 12th five-goal period in franchise history.
"The last seven or eight games, I think we've really found our game," Bennett said. "We're starting to find some confidence. We're definitely having a lot of fun playing hockey right now."
Not going down without a fight, Rem Pitlick and Josh Anderson both scored at 2:12 and 8:06, respectively, of the third period to cut Montreal's deficit to 5-2. Speaking of fighting, there was also a lot of that. Over the final 20 minutes, Tkachuk, Smith and Ryan all dropped the gloves.
That aggression stemmed from an incident in the first period when Canadiens defenseman Mike Matheson knocked Panthers forward Eric Staal out of the game with a questionable hit.
After the game, Maurice said both Bobrovsky and Staal would be re-evaluated on Friday.
At 9:11, Lomberg put the game out of reach when he re-directed a pass from Carter Verhaeghe past Cayden Primeau, who relieved Montembeault to start the period, to put Florida on top 6-2.
"When you get a guy with that amount of respect in the locker room, a real veteran, a true pro and a leader, to see him get hit like that definitely lit a bit of fire under us," Lomberg said when asked about how the hit on Staal affected the rest of the game. "We wanted to make sure we got the two points because ultimately that's what he wanted us to do."
