On April 11, 2017, at the conclusion of his four-year collegiate career, Soucy was signed to a two-year, entry-level contract with the Minnesota Wild. He was subsequently re-assigned to the Wild's American Hockey League (AHL) affiliate, the Iowa Wild, for the remainder of the 2016–17 season.[7] Soucy was subsequently invited to the Minnesota Wild's development camp, where he was praised by Wild's director of player development Brad Bombardir for his play during the camp who said: "Carson Soucy just continues to improve and get better every development camp, and this was his fifth development camp. He continues to be one of the most improved, year in and year out, so I was happy with him."[8] After attending the Wild's training camp, Soucy began the 2017–18 season with the Iowa Wild.[9] After playing 67 games in the AHL, accumulating 15 points and a team-leading plus-12 rating,[10] Soucy was recalled to the NHL on April 2, 2018, following an injury to Ryan Suter.[11] He made his NHL debut against the Edmonton Oilers that night, registering three shots and two hits in 15:26 of time on ice. He became the fifth player to make his NHL debut with the Wild that season before being re-assigned to Iowa on April 6.[12]
The following season Soucy failed to impress at the Wild's training camp and spent the entirety of the 2018–19 season in the AHL.[13] When he returned to training camp for the 2019–20 season, he impressed Boudreau, who said: "This year, we didn't know what to expect. And he came in and he was aggressive, and he moved the puck well, and he defended well. So it was all good."[14] During this season, Soucy suffered an upper-body injury and was expected to miss 2–4 weeks to recover.[15] On October 5, 2020, Soucy signed a three-year, $8.25 million contract extension to remain with the Wild.[16]
After two seasons with the Seattle Kraken, Soucy left the club as a free agent and was signed to a three-year, $9.75 million contract with the Vancouver Canucks on July 1, 2023.[18]
