That off-season, he was selected by the Winnipeg Jets 22nd overall in the 1981 NHL Entry Draft and immediately began playing for the team, making his NHL debut in 1981–82, appearing in 17 games. He was, however, returned to junior with the Royals, who had been realigned in the Ontario Hockey League (OHL), later that season. The reassignment to junior gave Arniel the opportunity to play at the 1982 World Junior Championships, helping Team Canada to their first-ever gold medal at the tournament.
