1978 42.75
1979 40.22
1980 46.47
1981 48.55
1982 51.88 (the elimination of the tight end is complete with everyone playing two slotbacks instead and the run-and-shoot emerges in Toronto)
1983 51.61
1984 50.67
1985 45.36 (a drop in the level of quarterbacking, especially in the east where Ken Hobart was MOP and Condredge Holloway was injured)
1986 47.90
1987 53.07 (the rise of some good, young QBs such as Renfroe, Austin, Burgess, Dunigan, and Allen. The # of teams in the league reduced from 9 to 8)
1988 50.28
1989 54.57
1990 61.86 (the peak years of offence are '91 and '92 with outstanding quarterbacking being the key. Doug Flutie is "lights out" during the 1991 season)
1991 64.15
1992 57.39
1993 55.25 (the beginning of U.S. expansion)
1994 57.19
1995 53.61 (the final season with American-based teams)
1996 50.96
1997 53.01 (the final year for Doug Flutie and the number of teams is once again reduced from 9 to 8)
1998 49.76 (concern over the seeming dearth of promising, young QBs arises)
1999 50.10
2000 57.68 (Anthony Calvillo emerges as a bona fide star QB in Montreal and Henry Burris lights up the scoreboard in Regina)
2001 48.29 (Calvillo misses much of the second half of this season with an injury. Dave Dickenson and Burris have both left for the NFL)
2002 51.22 (rookie Ricky Ray emerges in Edmonton and the Ottawa Renegades make their debut)
2003 52.68
2004 53.06
2005 53.90 (the final year for the Ottawa Renegades)
2006 46.67 (blocking rules are tightened on kick returns for this season resulting in fewer good returns; concern over quality of QBs returns)
2007 49.11 (Kerry Joseph is MOP and only QB to start every regular season and post-season game for his team)
2008 56.24 (Calvillo and Burris lead the return of the offences. Stubler's defence peters out in Toronto finally)
2009 51.26
2010 52.92
2011 50.28
2012 51.81
2013 52.40 (despite so many injuries to quarterbacks, offensive coordinators do an excellent job preparing backups and general managers and scouts do an excellent job of finding quality quarterbacks)
2014 45.48 (rosters expanded by two players; penalties increased substantially with much of that increase happening on offence and special teams plays)
2015 49.19 (scoring was up almost 4 points per game with new illegal contact, convert and punting rules in effect; a CFL record 27 different QBs started games this season)
2016 52.91 (offences returned this season as QB injuries were greatly reduced; of the five starting western QBs, only Darian Durant missed a couple of starts this season but the rest stayed healthy for the entire season)
2017 53.09 (highest scoring season since 2008; few QB injuries this season contributed to dynamic offensive play around the league)
2018 50.84
2019 49.49
2020 No season due to COVID pandemic
2021 43.10 (lowest scoring season since 1979)
2022 50.44
