Following the Games, he joined the Nordiques making a memorable debut on February 26, 1984, by blanking the St. Louis Blues 5–0.
The following year he formed a tandem with veteran Dan Bouchard and took over the starting job for good by playoff time helping backstop the Nordiques past the Buffalo Sabres in the first round and their fierce rivals the Montreal Canadiens in the second round before falling to the Philadelphia Flyers in the Semi-Finals.
His season ended on a high note, however, when Gosselin excelled for the Nordiques in the post-season going 7-4 after taking over the crease from Malarchuk.
He spent the next season in a backup role but returned to the starting job in 1987-88 after Malarchuk was traded to the Washington Capitals.
Gosselin served as the back-up to Kelly Hrudey but was largely ineffective posting a 7-11-1 record with a 3.87 goals against average.
After retirement, Gosselin worked as a radio analyst for the Roadrunners games and hockey coordinator at the YMCA before moving back to the province of Quebec in 1997.
