Voted "North American Player of the Year" in the North American Soccer League by the Professional Soccer Writers of America (PSRA) in 1980, Jack posted an NASL leading 0.91 goals-against average, while playing every minute of every game in goal for the Seattle Sounders. While he began his NASL career with the Toronto Metros in 1974 and continued with the Metros-Croatia in 1975, it was as Canada's goalkeeper during the 1976 Olympic Games in Montreal that he first attracted attention. His performances then won him a spot in goal for the Rochester Lancers in 1977 and he played all 26 games during the regular season and six more in the playoffs.
In 1978 he played in New York with the Cosmos, helping them win the Soccer Bowl. He then toured Europe and South America with the Cosmos that winter. Part way through the 1979 season he moved to the Tulsa Roughnecks and then to the Seattle Sounders for 1980, before finishing his career with the Tampa Bay Rowdies in 1982. His NASL career saw him play in 132 regular season games with another 21 in the playoffs. With Canada's national teams, Jack played seven games for the full national team and twice for the Olympic team. He is currently coaching in the youth program of Oakville Soccer Club.
