The Toronto Marlborough Athletic Club was started in Toronto, Ontario in 1903 by a group of Toronto sportsmen. It was named after the Duke of Marlborough. A hockey program was started in 1904. The team was commonly known as the Marlboros or Marlies and was also nicknamed the Dukes.
In the early years, the Marlboros were just one of many athletic clubs and junior hockey teams in and around Toronto that played in relative obscurity in the history books. The club was thrust onto the national scene in 1927 when Conn Smythe bought the Toronto Marlboros to be the farm team for his other recently acquired team, the Toronto Maple Leafs. From 1927 to 1989 the Marlboros and Maple Leafs shared common ownership first in the Smythe family and later in Harold Ballard. Upon the death of Conn Smythe, his son Stafford Smythe inherited the teams, and later sold a portion of both clubs to Harold Ballard. Ballard became sole owner of both teams upon the passing of Stafford Smythe.
The Marlboros served as a farm team for the Maple Leafs for 40 years until direct NHL sponsorship of junior teams ended in 1967; however, the two clubs continued to remain affiliated under a common ownership until 1989. During this time the Marlboros sent over 180 players to the NHL, including six future Hockey Hall of Fame inductees. The two teams often played double headers on Saturdays, with the junior games in the afternoon and the NHL games in the evening.
The original Hot Stove Club was formed at Maple Leaf Gardens on May 28, 1937, for the purpose of raising funds to support the Marlborough Hockey Club. The Hot Stove Club was given a permanent bar & lounge at Maple Leaf Gardens in 1963. From 1929 to 1975 the Marlboros won the national junior championship seven times.
Marlboro players from the Memorial Cups in the 1950s and 1960s jumped directly to the Maple Leafs, helping them win the Stanley Cup four times in the 1960s. Former NHL stars stayed in the organization to help coach in the junior ranks. Turk Broda and George Armstrong both coached the Marlboros to Memorial Cup victories.
Stafford Smythe organized the Metro Junior A League in 1961 as a rival league to the OHA, with the Marlboros as its charter member. After the league folded in 1963, the Marlboros scooped up all the former stars from the Toronto Neil McNeil Maroons who had won two consecutive Metro Junior A league titles, and also retained their coach, Jim Gregory. The 1964 Marlboros were one of the strongest teams in Canadian junior history.
The Marlboros returned to prominence again in 1973, coached by former Toronto Maple Leafs captain George Armstrong. Armstrong's team in 1973 lost only seven games all season, and two years later he coached the Marlboros to their seventh national title in 1975.
The team began to take a decline in the standings in the late 1970s which continued through the 1980s. Many people[who?] felt that Harold Ballard's penny-pinching ways helped contribute to the demise of Canada's most successful junior team. After the 1988-89 season the Toronto Marlboros were sold, and they severed ties with the Maple Leafs. The OHA team moved to Hamilton, becoming the Dukes of Hamilton. They were not financially successful in Hamilton, though, and after only two seasons the Dukes became the Guelph Storm.
