Montreal crushed the Detroit Red Wings, 8-1 behind Andrew Shaw's hat trick and Max Domi's five-point performance.
Domi scored twice and had three assists in Montreal's third win in nine games, putting the Habs sixth in the East and keeping them one point ahead of Pittsburgh and Carolina.
The Red Wings' losing streak stands at six games with Anthony Mantha scoring Detroit's lone goal in the second period.
Netminder Jimmy Howard was pulled in the second after allowing six goals on 22 shots and Jonathan Bernier made 10 saves in relief.
The Wings are on the road for the next two NHL games.
They visit the Coyotes Saturday in Arizona and the Avalanche next Tuesday in Colorado.
