Pettersson was traded from the Pittsburgh Penguins to the Canucks midway through the 2024-25 season. During his 31 games for Vancouver, the 29-year-old recorded 11 points while averaging 21:09 of ice time. The Canucks also wasted little time signing him to an extension, as Pettersson agreed to a six-year deal worth $33 million less than a week after he was traded for.
