The Grey Cup is the name of the trophy awarded to the champions of the Canadian Football League (CFL), and is analogous to the Vince Lombardi trophy in the US National Football League. The Grey Cup was first awarded by Canada's Governor General in 1909. Every current CFL team has won the Grey Cup. Teams that have won the Grey Cup in the last 60 years, but no longer play in the CFL, are the Baltimore Stallions* and Ottawa Rough Riders. No other teams have won the Grey Cup since the end of World War II. The Baltimore Stallions are the only team not based in Canada to have won the Grey Cup. (*The Baltimore Stallions are now the Montréal Alouettes.)
