Canadian Football League
The CFL considers the current Montreal Alouettes franchise (founded in 1994 as the Baltimore Stallions, moved to Montreal and renamed the Montreal Alouettes in 1996) to be a continuation of the original Montreal Alouettes (founded 1946, played in the CFL 1958–1981) and Montreal Concordes (founded 1982, renamed the Montreal Alouettes in 1986, folded just before the 1987 season). However this does not include the Montreal Football Club that was formed in 1872, and joined the IRFU in 1907–1915, and the Montreal AAA Winged Wheelers, who played in the IRFU during the 1930s and 40's, winning the Grey Cup in 1931.
