Pierre-Luc Dubois scored twice and added an assist to give the Columbus Blue Jackets a 4-3 win over the Canadiens to sweep the season series with Montreal.
Vladislav Gavrikov and Gustav Nyquist, into the empty net, also scored for the Blue Jackets (28-16-9), who have not lost in regulation in eight consecutive games.
Goaltender Elvis Merzlikins made 27 saves and improved to 10-2-0 since replacing injured starter Joonas Korpisalo.
Tomas Tatar, Max Domi and Shea Weber scored for the Canadiens (24-23-7), who remain eight points out of a playoff spot with 28 games left.
Making his second start in as many days, Carey Price stopped 23-of-26 shots in defeat.
Both teams were playing the second game of a back-to-back series. Columbus lost 2-1 in overtime to the Buffalo Sabres on Saturday while Price blanked the Florida Panthers 4-0 in Montreal.
The Jackets have beaten the Canadiens in four straight games, including all three meetings this season.
