In 1911/12, the club was reactivated and returned to their amateur roots by joining the Interprovincial Amateur Hockey Union. In 1912/13, they joined the Montreal City Hockey League. They played in that league until 1924 when the Shamrocks finally folded. Outside of the popular senior team, the Montreal Shamrocks had two lower tier teams. First was an intermediate team that played from 1896 through 1912. From 1896 to 1898 they played in the "Intermediate Amateur Hockey Association of Canada" (IAHAC). Then, from 1899 to 1912, they played in the "Intermediate Canadian Amateur Hockey league" (ICAHL). There was also a junior team that played from 1902 through 1916. In 1902 they played in the "Junior Montreal Hockey League". In 1903 they played in the "Independent Junior League". From 1904 to 1908, they played in the "Junior Amateur Hockey Association of Canada" (JAHAC). The team became dormant in 1909 but returned in 1915. They would fold after the 1916 season. While the lacrosse club was a predominately working-class team, based largely in the Irish Catholic industrial working-class neighbourhood of Griffintown, the hockey club reflected a more bourgeois background, more in keeping with the image the Shamrock Amateur Athletic Association wished to convey to the wider community of Montreal, as Irish Catholics attempted to integrate into the mainstream of the city's body politic in the late 19th century. Many of the players on the Stanley Cup–winning teams of 1899–1901 went on to study at McGill University, and entered into the city's bourgeois professional ranks as doctors, lawyers, and businessmen. Harry Trihey, the captain of the Cup-winning teams, became a prominent Montreal lawyer and, during World War I, was commissioned by the Government of Canada to raise the Irish Canadian Rangers, a venture that ended with Mr. Trihey resigning his commission and returning to Montreal in 1916 after the British High Command reversed its earlier promise to Mr. Trihey to send the Rangers into battle as a unit, deciding instead to plug them into the front line as reinforcements. Trihey also had problems recruiting in Quebec and Ireland following the GPO Rising in Dublin at Easter 1916. The following players have been inducted into the Hockey Hall of Fame:
