With the demise of the Montreal Alouettes on the eve of the 1987 season the playoff format reverted to the top three teams in the respective divisions making the playoffs (as it happened, no fourth place team achieved the league's sixth best record prior to U.S. expansion), while four teams qualified for the playoffs in 1993 and 1994. In 1997, the present cross-over rule was implemented, allowing the fourth-place team from one division to take the play-off place of the third-place team in the other division, should the fourth-place team earn a better record. From 1997 to 2016, the fourth place team in the West has taken advantage of the cross-over rule nine times, including four times when there were equal teams in the divisions. However, it was not until 2008 that a Western team (Edmonton) advanced to the Eastern Final, and only four other teams (the 2009 BC Lions, 2016 Eskimos, 2017 Saskatchewan Roughriders and 2019 Eskimos) have won a game since. Neither crossover team won more than one playoff game. As of 2019, no team from the East has crossed over into the Western playoffs.
