The 2011 CFL season was the 58th season of modern-day Canadian football. Officially, it was the 54th season of the Canadian Football League. The complete schedule was released on February 18 and featured the defending Grey Cup champion Montreal Alouettes opening the season against the visiting BC Lions on Thursday, June 30, 2011. The season was among the most notable in the modern era for the competitiveness of the teams; going into the final week, five teams were tied for first place in the league, a first in modern CFL history. It was also the first time since 1982 that all teams finished with fewer than 12 wins in the regular season. As well, for the first time since 1950, the start of the modern era, all four teams competing in the division finals were different from the four teams that had competed in the division finals the previous year. Newly renovated BC Place Stadium in Vancouver hosted the 99th Grey Cup on November 27, with the hometown Lions defeating the Winnipeg Blue Bombers 34-23 in front of a sold-out crowd.
The CFL returned to Moncton for the second installment of the Touchdown Atlantic series. The Hamilton Tiger-Cats were the home team, while the Calgary Stampeders were the visitors with the game having taken place on Sunday, September 25.
When the 2011 schedule was released, it was revealed that the typical Labour Day Classic match-up featuring the Hamilton Tiger-Cats hosting the Toronto Argonauts would not occur this year for the first time since 1995. Instead the Tiger-Cats will play host to the Montreal Alouettes and then visit the Alouettes the following week as a part of a home-and-home series. While the fan reaction was heated, Commissioner Mark Cohon explained that due to a lack of available home dates for the Argonauts, Toronto would be hosting a game against the BC Lions that weekend, necessitating the need for the change. This was the ninth time that Hamilton played Montreal on the Labour Day weekend.
On April 14, 2011, it was announced that four significant rule changes would be introduced for the 2011 season. The following changes were implemented:
For the third consecutive year, the Canadian Football Hall of Fame induction weekend events took place outside of Hamilton, Ontario, the home of the museum. It took place in Calgary from September 14 to 18, with the hall of fame game itself featuring the Calgary Stampeders hosting the BC Lions on Saturday, September 17, 2011.
According to the new collective bargaining agreement, the 2011 salary cap will be set at $4,300,000. As per the agreement, the cap is fixed and will not vary with league revenue performance. The minimum team salary will be set at $3,900,000 with individual minimum salaries set at $43,000.
Teams play eighteen regular season games, playing divisional opponents three or four times and teams from the opposing division twice. Teams are awarded two points for a win and one point for a tie. The top three teams in each division qualify for the playoffs, with the first place team gaining a bye to the divisional finals. A fourth place team may qualify ahead of the third place team in another conference (the "Crossover") if they earn more points in the season.
If two or more teams in the same division the following tiebreakers apply: 
Note: GP = Games Played, W = Wins, L = Losses, T = Ties, PF = Points For, PA = Points Against, Pts = Points
