Founded in 1948, it was not until the early 1950s that the Montreal GAA adopted the name of ‘Montreal Shamrock Hurling and Football Club’, Able to form an inter-squad league which consisted of five teams in hurling and four teams in football. Out of that league sprang the nucleus of the team that not only topped its Division, but also captured the Northern Division of the American League from Toronto at Kingston on October 4, 1959. Two years later, the Montreal Hurling team won the American Senior Championship against Boston GAA, while on the same day at Loyola Park in Montreal, the Montreal Football team narrowly lost to Boston Galway in a hectic final.

In May 2018 during the club’s 70th anniversary. The Montreal Shamrocks created the Hall of Shamrocks to recognize and remember the work put in by retired members. The first members inducted Martin Greene & Paul Moran were given honorary club president status.
