Post-Olympic use
The Montreal Alouettes of the Canadian Football League became the first professional team to use the stadium after the Olympic Games when they moved into the facility midway through the 1976 season, and used it until 1986. This team returned to the facility for the 1996 and 1997 seasons, and currently only uses it for certain regular-season games and their postseason games.
The stadium hosted the Gray Cup, the CFL championship game, in 1977, 1979, 1981, 1985, 2001 and 2008. The stadium holds the record for the nine largest attendances for CFL games. The largest attendance at a game occurred on September 6, 1977, when 69,093 spectators attended the game between the Alouettes and the Toronto Argonauts.

The Expos played five postseason games at home in 1981; two against the Phillies and three in the National League Championship Series against the Los Angeles Dodgers. On October 19 of that year, the Expos lost the decisive fifth game, with a score of 2-1. In 1982, the Major League Baseball All-Star Game was held at Olympic Stadium in front of 59,057 spectators—a record for baseball games at the stadium. Prior to the 1992 season, a major remodeling of the ballpark took place. The new design put spectators closer to the action and reduced the venue's capacity to 46,000 people.
