In the early 1970s, the Toronto Nationals also had an entry in the Metro Junior B Hockey League who were 1973 Metro Champions and runners up for the Sutherland Cup All-Ontario title. The 1975-76 season saw a 14-year-old Wayne Gretzky challenge the wishes of the Canadian Amateur Hockey Association and sign with the Toronto Nationals. Barely 16 years old, Gretzky had played two seasons with the Nationals and scored 63 goals for 132 points in just 60 games. The Nationals won the 1977 Metro championship, led by the young Gretzky with 75 points in just 23 playoff games. The next season, he signed with the Sault Ste. Marie Greyhounds, a quick stop before going professional and starting what is considered by many hockey enthusiasts as the greatest career in hockey history.
