|59th Grey Cup|
The 1971 CFL season is considered to be the 18th season in modern-day Canadian football, although it was officially the 14th Canadian Football League season.
The Grey Cup Championship was played on artificial turf for the first time in Vancouver. The BC Lions also wore special "CCC"-logo helmets to commemorate the Canadian Confederation Centennial of British Columbia, the province having entered into Canadian Confederation a hundred years earlier, in 1871. The flower in the centre of the "CCC" logo is the pacific dogwood, the official provincial flower of British Columbia.
All CFL teams had their player's last names appearing on the jersey backs (at shoulder height, above the back number) beginning this season.
This would be the last year until 2006 that the Edmonton Eskimos would miss the playoffs; in the intervening years, they would reach the playoffs for 33 straight years.
