The Maple Leafs finally reached the NHL's peak two seasons later. Armstrong set a career high with 53 points in the 1961–62 regular season, then added 12 points in 12 playoff games for Toronto. He started the play that resulted in the Stanley Cup clinching goal, rushing the puck up ice before passing to Tim Horton, who then passed to goal-scorer Dick Duff that capped off a 2–1 victory in the sixth and deciding game of the series against the Chicago Black Hawks. As Maple Leafs captain, Armstrong was presented the trophy by league president Clarence Campbell. It was the first of three consecutive championships for Toronto as the Maple Leafs of 1962–1964 became the fourth dynasty in NHL history. Individually, Armstrong scored 21, 19 and 20 goals over the three seasons and by virtue of the NHL's All-Star Game format of the time that had the defending champion play the all-stars of the remaining teams, appeared in his fourth, fifth and sixth All-Star Games. Early in the 1963–64 season, on December 1, 1963, Armstrong scored his 200th career NHL goal.
