Derek Lalonde Is Just What the Montreal Canadiens Need – Hockey Writers – Montreal Canadiens

The Montreal Canadiens made an unexpected coaching change this week when Trevor Letowski, who played for the Martin St. Louis for five seasons, resigning as an assistant coach to spend more time with his family. The Canadiens quickly filled the void by hiring Derek Lalonde, the former Detroit Red Wings head coach and longtime Tampa Bay Lightning assistant, who had just been released by the Toronto Maple Leafs.
The Coach Who Left His Mark on the Room
Letowski’s five seasons in Montreal were defined as much by his relationship with the players as by whatever he drew on the whiteboard. He joined the Canadiens in the summer of 2021 after ten years coaching in the Ontario Hockey League (OHL), first with the Sarnia Sting and then the Windsor Spitfires.
He won the Memorial Cup as an associate coach in 2017 before becoming head coach the following season. His path to the NHL bench came through Dominique Ducharme, with whom he coached at two World Junior Championships, including a gold medal run in 2018.
When Letowski was hired in 2021, he described the job as player relationships rather than tactics. He said part of his role as an assistant is to keep stars like Cole Caufield and Nick Suzuki comfortable during the NHL season, something he can relate to as a seventh-round pick who fought for every opportunity.
Why Time Can Work in Montreal
Being popular and being the right fit that a team needs at a given time is not always the same. Montreal’s penalty kill was a problem for most of last season, despite signs of improvement late in the regular season and the playoffs. That’s not a knock on Letowski’s value as a coach or person, or a claim that the penalty kill was solely his responsibility. Player development and management are real skills, and the Canadiens appreciated what he had to offer.
But the big problem is, or maybe it was justifiable: NHL coaching staffs need more than one strength. The defensive structure and special teams have been Montreal’s most obvious soft spots. The Canadiens built something real under St. Louis, with a roster composed of a young core and a blue line led by Lane Hutson, who is producing at a high level in the backfield. What that team lacks is a coach whose NHL record is built on tactics, systems and more than just motivation and trust.
Lalonde Happened To Be Found At The Right Time
Tactics and systems are exactly what Derek Lalonde brings to the table, drawing on over 30 years of coaching experience. Most notably, he spent four seasons as an assistant for the Tampa Bay Lightning from 2018 to 2022, helping the team win back-to-back Stanley Cups.
While no single assistant coach deserves full credit for the roster, Lalonde’s impact on Tampa Bay’s defense was well-documented and has followed him throughout his career. That’s the real value of Montreal: adding a coach with a proven track record in a position that Canada desperately needs.
Part of what makes that stretch so important is who Lalonde learned from during his time. He spent those four years working for Jon Cooper, one of the most respected bench managers of his generation and builder of a Tampa Bay dynasty that reached three straight Stanley Cup Finals. Cooper’s staff is known for pushing structure and detail on a roster loaded with offensive talent, and Lalonde was in the room for all of that, tasked with the special defense and special side of that equation.
That kind of learning under a coach of Cooper’s caliber, combined with the two titles it produced, is not something many assistant coaches get to document. Montreal didn’t go out and buy that kind of experience when the week started, but Letowski’s decision created an opening, and Lalonde’s availability is exactly what a rookie in the NHL grind could use.

His recent stance cemented the same reputation. Last season in Toronto, Lalonde helped guide the Maple Leafs to a top-10 penalty kill in the league, a mark better than what Montreal produced during the same period. He also spent two and a half seasons as head coach in Detroit, where the results were mixed, but even that stretch began with him pointing to team defense and special teams as specific areas the Red Wings needed to fix.
Lalonde is also expected to step into a bigger role than a regular assistant. Reports from Montreal describe him as the lead assistant for St.
The assignment reflects the organization’s confidence in what Lalonde brings. Instead of simply replacing Letowski with someone like him, the Canadiens brought in a coach whose strengths align with perhaps their greatest need.
The Great Image of St. Louis and the Canadiens
None of this diminishes what Letowski meant to this Canadiens team. What was revealed about his exit this week described him as someone who was highly respected in the organization, and the team’s desire to keep him around in some way reflects that. But hockey decisions rarely come down to one factor, and a random move can end up fixing a problem the team knew it had, even if that move and that problem were never connected.
Montreal spent last season watching their defensive line bend and unravel against elite competition, and now they have a coach on staff whose entire NHL CV is built to prevent just that. Letowski’s exit was not a weakness on his part or a response to Montreal’s defensive mistakes but an opportunity for the Canadiens to address a problem they already knew they had.
Lalonde is one of the most qualified coaches available for the specific job Montreal needs. Now it will be seen how quickly he meets Martin St. Louis, the entire coaching staff, and the players. If that transition goes well, the Canadiens will be addressing one of their biggest weaknesses, and moving on from last season will need to strengthen their defensive game as much as anything they do offensively.
