[12] He then skated in three games with Montreal's American Hockey League (AHL) affiliate, the Laval Rocket[13] and would be limited to just two appearances with the Raiders once major junior play commenced due to a hand-injury.

[15] He would ultimately return to Prince Albert for the 2021–22 season,[16] registering fifteen points through 17 games before being traded to the Edmonton Oil Kings on December 1.

[18] After missing the final weeks of the regular season due to injury, he returned for the first game of the 2022 WHL playoffs, and scored three goals and two assists in the Oil Kings' opening round sweep of the Lethbridge Hurricanes.

[19] After likewise sweeping the Red Deer Rebels in the second round,[20] the Oil Kings would advance to the WHL Finals after defeating Winnipeg in five games.

[23] He was named the WHL Playoff Most Valuable Player at the conclusion of the series, setting a team record for most goals by a defenceman in a single postseason (8).

"[26] After his performance across pre-season action, Guhle was widely considered one of the most impressive young players in the Canadiens system and was a perceived frontrunner to make the team's defensive lineup.

[28] In his NHL debut on October 12, Guhle played a team-leading 22:34 minutes of ice time in a 4–3 victory over the Toronto Maple Leafs.

[29] With injuries to the team's more senior left-side defencemen Mike Matheson and Joel Edmundson, Guhle continued to play top-line minutes for the Canadiens.

[35] Guhle spent most of the 2023–24 season playing on the Canadiens' top pair alongside Mike Matheson, which necessitated a move to the right side, a position where the team had less depth than its counterpart.

[41] Entering the 2024–25 season on the final year of his entry-level contract with the Canadiens, Guhle signed a six-year, $33.3 million extension with the team on July 31, 2024.

[26] In the aftermath of the 2023–24 NHL campaign, Guhle indicated that he had been invited to join the national senior team for the 2024 IIHF World Championship, and would compete if he was able to sufficiently recover from a head injury in time.
