If you could go back in time and visit any one of these former CFL stadiums, which one would it be?
BC's Empire Stadium: Used 1954 - 1982, Demolished 1993

Since there has already been so much discussion on the Lions' previous stadium, I don't say too much. My first time inside Empire Stadium was in 1979 and that was to see a Whitecaps game.
Montreal's Autostade: Used 1968-71, 1973-76, Demolished late 1970's

I don't know too much about this stadium other than it hosted the 1969 Grey Cup and 1971 CFL All-Star game. The Montreal Impact soccer team said that they will build a new stadium at its current location.
Montreal's Delorimier Stadium: Used 1946 - 1963, Demolished late 1960's
This stadium seated 20,000 and also hosted the Montreal Royals International League baseball team from 1928 to 1960.
Toronto's Exhibition (CNE) Stadium: Used 1959 - 1988, Demolished February 1, 1999

Everyone complained that this stadium had a very bad configuration for baseball. Heavy rain seemed to affect the play of the Argos in several important games like the 1982 GC and the 1988 EDF. Towards the end of the lifespan, I remember the Lions had a hard time winning there as they lost there in October 1987 (2nd of 3 losses that costed Don Matthews his job) as well as their first loss of the 1988 season in game 3. Varsity Stadium has been heavily renovated but still exists so I won't list that here.
Hamilton's Amateur Athletic Association (AAA) Grounds: Used 1872-1949

It looks like only the field and a racing track still exist. The Tiger-Cats used this field for 78 years!

Winnipeg's Osborne Stadium: Used 1935 - 1952, Demolished late 1950's
Capacity was only 7,800.
Edmonton's Clarke Stadium: Used 1954-1978, Demolished May 3, 2000


I drove by this place in 2004. The field still exists but its new grandstand only seats 1,200. In aerial views after Commonwealth Stadium was built which showed the stadiums side by side such as the second picture above, I always thought that Clarke stadium looked like Commonwealth's little brother. I wonder if there was any other city that had two football stadiums right beside each other.
Calgary's Mewata Stadium: Used 1935 - 1959, Demolished 1999


This stadium was just west of Calgary's downtown area and has now been converted to Shaw Millennium Park which features a large skateboard park. I couldn't find any pictures of this stadium, only how the site looks like now.
