[5] After four years with the Rangers, Lefebvre left the NHL and decided to join old friend Sebastien Bordeleau for one season with Swiss-based SC Bern of the Nationalliga A where he and his team won the league championship prior to his retirement from active play.

[6][7] On June 4, 2009, the Colorado Avalanche announced that Lefebvre would serve as an assistant coach of the team's American Hockey League (AHL) affiliate, the Lake Erie Monsters.

Following the Canadiens' purchase and subsequent relocation of the Bulldogs franchise to become the second iteration of the St. John's IceCaps in 2015, Lefebvre was kept on as head coach.

[10] After finishing with the worst record in the AHL during the team's inaugural 2017–18 season, Lefebvre was relieved of his head coaching duties in April 2018.

As part of tradition, each player on the winning team can take personal possession of the trophy for a day during the summer following the championship series, a practice that has led to several misadventures.
