The Canadian Football League's Montreal Alouettes became the stadium's first major post-Olympic tenant when they moved their home games there halfway through the 1976 season. Capacity was reduced from its Olympic capacity of 72,000 to 58,500, but leapt to 66,308 when the natural grass was replaced with AstroTurf ahead of the 1977 season. The Alouettes remained there through 1986, the franchise's final season of operations; the team would shut down shortly after the start of the 1987 season. A revived Alouettes franchise returned for the 1996 and 1997 seasons, but then moved to the Percival Molson Stadium in 1998, only using the larger Olympic Stadium for select regular-season and home playoff games. As of 2008, the franchise uses Olympic Stadium for playoff games only. Due to the increased popularity of the Alouettes and the small capacity of Percival Molson Stadium, the team considered returning to Olympic Stadium on a full-time basis, but instead renovated Percival Molson Stadium to increase its capacity. In addition, the stadium holds the record for the largest Grey Cup attendance, that of the 1977 Grey Cup game, in which the hometown Montreal Alouettes defeated the Edmonton Eskimos, 41-6 before 68,318 spectators; this despite a local transit strike and harsh winter weather conditions.
