Since their founding in 1909, the Montreal Canadiens have been involved in several trades with teams across the NHL over multiple decades. There have been some high-profile players moved in and out of the team, with the Canadiens by far the most successful team in league history.
But not all trades can be successful, and many of them could even be considered regrettable for various reasons. Whether that’s because the results that followed a trade disappointed, or a fan favourite was moved under difficult circumstances, or someone with a bright future was lost due to the team’s desire to win now, there have been many regrettable trades in franchise history.
Here are some of the most regrettable trades for the Montreal Canadiens.
Naturally, the best trade to begin with is arguably the most infamous in franchise history. Patrick Roy is still viewed as one of the top three goaltenders in the history of the NHL. He is regularly discussed alongside Dominik Hasek and Martin Brodeur in debates over who deserves the title outright.
Entering the 1995-96 season, Roy had already lifted the Stanley Cup twice alongside a plethora of individual awards, including two Conn Smythes, three Jennings Trophies, and two Vezina Trophies. The problem was that the Montreal Canadiens were disappointing in 1994-95. They had just 18 wins in the lockout-shortened season, finishing sixth in the Adams Division and missing the post-season.
After starting 0-4-0 the following season, Jacques Demers was replaced by first-time head coach Mario Tremblay. General manager Serge Savard was also ousted in favour of Réjean Houle. Tremblay had a long playing career with the Canadiens, winning five Cups and even being a roommate with Roy during the earlier stage of the goaltender’s own career.
After retiring, though, Tremblay and Roy’s relationship strained, with the former regularly commenting on him as part of his radio career, which nearly led to a physical confrontation between the pair. Despite this animosity with their star, Canadiens ownership felt that Tremblay was the man to get things back on track.
Results did improve under Tremblay, with the Canadiens going 12-3-1 before facing the Detroit Red Wings in what would become one of the most infamous games in history. On December 2nd 1995, at the Montreal Forum, the Canadiens suffered a devastating 11-1 loss. By the end of the first period, Roy had allowed five goals on just 17 shots. However, Tremblay did not pull him from the game and kept him in for another four goals. His team was down 9-1 before Roy was eventually pulled from the game.
This was the final straw for the goalie. He immediately went to team president Ronald Corey and told him he would never play for the team again. Roy was suspended by the team. Four days later, he was sent to the Colorado Avalanche in a package deal alongside team captain Mike Keane for Jocelyn Thibault, Martin Ručinský and Andrei Kovalenko.
Roy continued to have great success with the Avalanche. They won the Cup the year he was traded and winning another in 2001. He picked up his third Conn Smythe trophy. He added another Jennings in 2002 before retiring in 2003. For the Canadiens, Tremblay lasted just one more season, and the deal is still viewed today as one of the most lopsided trades in NHL history.
Losing a future Hall of Famer, and seeing him succeed so much after leaving the team, for a coach who would never be a head coach in the NHL again, and arrived at the team already on negative terms with the star goalie, is surely one of the most regrettable decisions, let alone trades, in Montreal Canadiens history.
This next trade had far less of an impact compared to Patrick Roy’s departure. It is still another significantly lopsided deal when considering the entire picture in the aftermath.
Many people may not associate defenceman Ryan McDonagh with the Montreal Canadiens. He had a long career with the New York Rangers and Tampa Bay Lightning. However, he was the Canadiens’ 12th-overall selection in the 2007 Draft.
The 2007 Draft class is already impressive for the Canadiens considering they also picked Max Pacioretty and P.K. Subban, but it could have been even greater had the team kept McDonagh around instead of trading him for Scott Gomez. Both players were part of a much larger package. Tom Pyatt and Michael Busto went to Montreal, and Chris Higgins, Doug Janik, and Pavel Valentenko went to New York.
However, they were the key pieces to the deal. Gomez won the Calder Trophy as the league’s best rookie in the 1999-2000 season. He had two Stanley Cups to his name by the time he was dealt to the Canadiens in 2009. The team needed a top-line centre, and Gomez’s consistency during his time in the NHL was considered sufficient to forgo a top defensive prospect such as McDonagh.
The Canadiens got 196 games out of Gomez, with increasingly diminishing returns over the next three seasons, before he was bought out in January 2013. McDonagh, meanwhile, has been a solid defenceman for both the Rangers and Lightning, playing 1058 games with 441 points (86 goals, 355 assists), and lifted the Stanley Cup twice in 2020 and 2021.
Imagine if the Canadiens had opted to keep McDonagh, potentially creating a defensive partnership between him and Subban for years to come. It’s a decision that many in the organisation no doubt look back on and wish could have played out differently, with McDonagh still playing at the age of 37 while Gomez, 10 years McDonagh’s senior, hung up his skates after the 2015-16 season.
Another trade where the Montreal Canadiens gave up a talented young defenceman in favour of help at forward saw Mikhail Sergachev traded to the Tampa Bay Lightning for Jonathan Drouin. Sergachev was the ninth-overall pick of the Canadiens in the 2016 Draft, while Drouin was taken third overall in 2013.
Drouin’s early seasons in the NHL were stop-start, with his third year in Tampa his best, with a then-career-high of 53 points (21 goals, 32 assists) in 73 games. This was enough to convince the Canadiens to part ways with Sergachev. He had played just four games in the NHL at the time of the deal.
Again, though, the Canadiens gave up a player who would go on to win multiple Cups in exchange for one who did not live up to lofty expectations. Sergachev, playing on a Tampa team that also had Ryan McDonagh, won back-to-back Cups in 2020 and 2021.
He has spent the last two seasons with the Utah Mammoth. In those seasons, he registered 53 and 59 points, respectively. He continues to be a premier player on the blue line in the NHL at just 28 years old. He has amassed 630 NHL games so far and could top 1,000 when all is said and done.
Drouin, meanwhile, has played just 41 games more than Sergachev. He is already 31 years old, and last played for the Canadiens three years ago. He did make 321 appearances over six seasons in Montreal. But injuries and inconsistent offensive production led to his release as an unrestricted free agent in 2023.
Stints with the Colorado Avalanche, New York Islanders, and St. Louis Blues have followed. But Drouin finds himself a UFA once again in 2026, while Sergachev is locked in for another five years at an AAV of $8.5 million.
