Born in Toronto, Ontario, Peter Ing was selected by the Leafs with their third-round choice, 48th overall in the 1988 National Hockey League Entry Draft.
A standout performer with the Windsor Spitfires of the Ontario Hockey League (who went 16-0 to become the first undefeated OHL championship team in history) and later the London Knights, Ing joined the Leafs and made his NHL debut on November 16, 1989 against the New York Islanders. Peter led all Toronto goalies in starts (56) during the 1990-91 season and set a franchise record 19 straight starts as a rookie goaltender, earning NHL rookie-of-the-month for December.
Ing may always be remembered for stopping the NHL's all-time leading scorer, Wayne Gretzky, on a penalty shot at a sold-out Maple Leaf Gardens and in front of a national TV audience on CBC's Hockey Night In Canada when the Los Angeles Kings faced the Leafs on January 5, 1991.
Ing was a part of the Leafs and Oilers memorable seven-player trade on September 19, 1991 which saw Grant Fuhr and Glenn Anderson join Toronto. He was traded to the Detroit Red Wings prior to the 1993-94 season and retired from professional hockey due to injury in 1996.
Ing won the Molson Cup Award with the London Knights in 1988-89, the Newmarket Saints (Leafs farm team) in 1989-90 and the Toronto Maple Leafs in 1990-91.
