"He's a dominant player when he's on his game, and we need that from him," Maple Leafs goalie Jack Campbell said of the forward. "He's such a special player and he's bringing it, so I think he's getting the guys going. And other guys are stepping up and ultimately everyone's doing the best they can, and Willie's leading."
Campbell made 14 of his 27 saves in the third period, and Morgan Rielly scored for Toronto, which is the No. 1 seed in the Scotia North Division and took the lead in the best-of-7 series.
"[Campbell] was unbelievable," Nylander said. "The work he put in before the playoffs started shows what it takes to compete at this level. He's been unbelievable for us, a huge part of our team."
Nick Suzuki scored for Montreal, the No. 4 seed. Carey Price made 27 saves, including a lunging stick save on Jason Spezza during a Toronto power play in the first period.
The Canadiens have scored four goals in the series, including a 2-1 win in Game 1.
"I'm not frustrated at all, to be honest," Price said. "I believe in these guys. These guys are talented guys, I see their shots in practice every day and I have no doubt that they have the ability to score a goal. They're trying out there, I know they are, and it's going to come. They're playing pretty solid defense on their side, but we're going to find a way to get through that. Their goaltender is playing well, we're going to have to make it more difficult for him."
