After playing junior hockey with the Stratford Kroehlers and the Toronto Marlboros, Armstrong made his NHL debut playing two games for the Toronto Maple Leafs in the 1949-50 season. In the 1951-52 season, while still being played sparingly, Armstrong became the first person of Native heritage to score a goal in the NHL. After earning a permanent roster spot with the Toronto Maple Leafs during the 1952-53 season, George Armstrong made an immediate impact. After impressing management with his hard work ethic, Armstrong was named captain of the Leafs upon Ted Kennedy’s retirement and Jim Thomson’s move to Chicago. Armstrong would captain the Leafs to four Stanley Cups in the 1960 and is the last Leaf’s captain to hoist the cup. Armstrong retired after the 1971 season and coached his former junior team, the Marlboros throughout the 1970s. Armstrong also coached the Leafs for part of the 1988-89 season and has been a scout with the organization for many years.
