The 1988 Canadian Football League season is considered to be the 35th season in modern-day Canadian football, although it is officially the 31st Canadian Football League season.

The Canadian Football Network reached an agreement with the CFL to extend its network for two more seasons.

Game rosters were revised to consist of 20-Non Imports, 14-Imports and 2-Quarterbacks. The reserve list was lowered from 4 players to 2 players. In addition, if a team decides to dress 14-Imports, one of those imports have to be designated as a special teams player.

On Monday, December 12, the CFL Board of Governors appointed Roy McMurty as Chairman-Chief Executive Officer and Bill Baker as President-Chief Operating Officer. Their appointments were confirmed on Sunday, January 1, 1989. The CFL Board of Governors also approved the sale of the Toronto Argonauts from Carling O'Keefe Breweries to Harry Ornest.
