Tyler Toffoli scored his first two goals for Vancouver since being acquired in a trade with Los Angeles earlier in the week, and added an assist as the host Canucks put an end to the league-leading Boston Bruins' five-game winning streak with a 9-3 victory Saturday night.

Defenseman Troy Stecher had a goal and two assists and J.T. Miller had three helpers for the Canucks, who snapped a two-game losing streak and improved to 3-4-2 in their past nine games.

Bo Horvat, Adam Gaudette, Tanner Pearson, Loui Eriksson, Elias Pettersson and Jake Virtanen also scored for the Canucks, and goaltender Jacob Markstrom made 34 saves. Alex Edler and Quinn Hughes added two assists apiece.

Boston's David Pastrnak scored twice, breaking a tie with Toronto's Auston Matthews for the NHL lead in goals. Pastrnak's third-period goal was his 45th of the season. Chris Wagner also scored for the Bruins.
