Steven Stamkos had two goals and added an assist and the Lightning beat the Canadiens 4-2 Monday night in a matchup of the Atlantic Division's top teams.
Both have 93 points, but Montreal has played one fewer game.
"It's definitely a confidence booster when you get the offence going in a game like this, especially down the stretch," Stamkos said.
Valtteri Filppula and Victor Hedman also scored for the Lightning, who have outscored Montreal 16-5 in winning all four games between the teams this season.
Montreal, which lost for the sixth time in eight games (2-4-2), got goals from Tomas Plekanec and Pierre-Alexandre Parenteau.
"We started off slow," Montreal centre Alex Galchenyuk said. "We didn't play a full 60 minutes and that cost us."
Stamkos secured the win with his 39th goal, an empty-net power-play goal with 1:05 to play.
Filppula opened the scoring during a power play at 10:07 of the first when his right circle shot was redirected by a sliding Montreal defenceman Andrei Markov past Carey Price.
Max Pacioretty made an ill-advised pass from neutral ice back into the Canadiens zone that Stamkos stole and made it 2-0 from the right circle with 4:02 left in the first.
"Funny things happen when we play Montreal," Tampa Bay coach Jon Cooper said. "It was a weird play."
Hedman put the Lightning up 3-0 after skating alone down the slot 2:45 into the second.
"They got a lucky bounce on the first goal. I gave them the second goal," Pacioretty said. "The third one was a good play. We played a good team game. Those things happen."
Plekanec tied Larry Robinson for 23rd place on the Montreal goals list with 197 after a power-play tally at 11:10 of the second.
Parenteau cut the Montreal deficit to 3-2 just 34 seconds into the third from the low slot after Plekanec stole goalie Ben Bishop's pass behind the net.
"I didn't do us any favours turning the pack over," Bishop said. "After that we kind of buckled down. One of those things where you bend and don't break."
The Canadiens had P.K Subban's drive hit the post and Pacioretty's breakaway shot stopped by Bishop during a six-minute stretch after Parenteau's goal.
Bishop, 9-1-2 against Montreal, made 32 saves. Price stopped 30 shots and is 10-10-5 against Tampa Bay.
Montreal centre Brian Flynn left with an upper body injury and didn't return after getting high-sticked by Brenden Morrow at 2:21 of the first.
Canadiens left wing Brandon Prust took part in two of the three fights, and also got a goalie interference penalty after checking Bishop into the end boards.
"It's hockey," Cooper said. "Prust, that's what he does. He tries to get under a teams' skin."
