The Montreal Canadiens have fired head coach Dominique Ducharme, with former Hall of Famer Martin St. Louis replacing him on an interim basis.

Ducharme, 48, was dismissed following a 7-1 rout at the hands of the New Jersey Devils, with Montreal rock-bottom of the league. 

That defeat means Montreal have lost 30 of their 45 games this season, the most of any NHL team the campaign after making the Stanley Cup final.

St. Louis, 46, takes over as a head coach for the first time in his career, having previously held the position of consultant with the Columbus Blue Jackets in the 2018-19 campaign.

"We are very happy to welcome Martin to the Canadiens organisation," general manager Kent Hughes said in a statement.

"Not only are we adding an excellent hockey man, but with Martin, we are bringing in a proven winner and a man whose competitive qualities are recognised by all who have crossed his path."

Hughes released another statement thanking Ducharme for his work over the past year, having stepped into the role of head coach in February 2021.

"We would like to sincerely thank Dominique for his work and contributions to the Montreal Canadiens organisation," Hughes said. 

"At this point in the season, we felt it was in the best interest of the club to make a change."

St. Louis' NHL career saw him play a combined 1,134 games for the Calgary Flames, Tampa Bay Lightning and New York Rangers, racking up 391 goals and 642 assists in that time.

Montreal are on a run of seven consecutive defeats – and 13 from their past 14 games – and have conceded 33 times in their most recent five outings, leaving their new head coach with a mountain to climb to turn things around.
