MONTREAL -- Tyler Toffoli scored 1:39 into overtime, and the Montreal Canadiens swept the Winnipeg Jets with a 3-2 win in Game 4 of the Stanley Cup Second Round at Bell Centre on Monday.
Toffoli won it on a one-timer from low in the left face-off circle off a cross-ice pass from rookie Cole Caufield after Nick Suzuki won a battle along the boards.
"I think that's definitely one of the bigger ones," Toffoli said about the significance of his goal. "It's fun right now. We're doing a good job, and it just kind of feels like we're all kind of playing as one."

Suzuki had two assists, and Carey Price made 14 saves for the Canadiens, the No. 4 seed from the Scotia North Division, who have won seven straight games and will play the Colorado Avalanche or Vegas Golden Knights in the Stanley Cup Semifinals.
"Obviously, we're excited about the opportunity, but we've got a lot of work ahead of us," Price said.
Montreal's winning streak is its longest in the playoffs since 1993, when it won 11 straight during a run to its most recent Stanley Cup championship.
"We can write our own story," Canadiens coach Dominique Ducharme said. "That's what we want to do."
Logan Stanley scored twice, and Connor Hellebuyck made 39 saves for the Jets, the No. 3 seed, who never led in the series.
"We just couldn't get the first goal," Winnipeg captain Blake Wheeler said. "We just couldn't do it all series, and that plays right into their hands, especially their top four defensemen. They're big and heavy and they do a great job of just clearing pucks and throwing them out of the zone."
The Canadiens have not trailed since Game 4 in the Stanley Cup First Round against the Toronto Maple Leafs, a series they won in seven games. Their streak of 437:53 is the second-longest in Stanley Cup Playoff history, behind the streak of 488:38 they set in 1960.
"They're playing at a really high level right now," Wheeler said. "You just have to give them all the credit."

Erik Gustafsson scored his first NHL playoff goal to give Montreal a 1-0 lead at 8:01 of the first period. He faked a one-timer before moving to the top of the slot for a shot that went in off the left post on the power play.
Artturi Lehkonen made it 2-0 with 51 seconds remaining in the first when he deflected Brett Kulak's wrist shot from the left point.
Stanley cut it to 2-1 at 1:40 of the second period. He received a pass from Josh Morrissey and skated to the left face-off dot before beating Price short side over his blocker.
Stanley then tied it 2-2 at 5:29 with a one-timer from above the right circle that Price missed with his glove. The defenseman scored one goal in 37 games as a rookie this season.
"You know that the team that's down has got their backs against the wall and they're going to bring their best effort," Montreal captain Shea Weber said. "So it's always the hardest one to close out and you know you don't want to give it too many chances. As you've seen in the past, things can turn around really quickly."
After the Jets tied it, the Canadiens outshot them 25-6 the rest of the way.
"[Hellebuyck] gives us a chance to win every night, and unfortunately we weren't able to score enough for him this series," Winnipeg forward Adam Lowry said. "But he gave us a chance every night to be in the game and we just weren't able to buy a couple."
NOTES: Montreal defenseman Jeff Petry did not play after leaving Game 3 with an upper-body injury. He was replaced by rookie Alexander Romanov, who had one shot on goal and one hit in 9:27 in his NHL playoff debut. … Montreal is the third team in NHL history to sweep a best-of-7 series after coming back from down 3-1 in the previous round, joining the Edmonton Oilers in 1990 and the Tampa Bay Lightning in 2011.
