The Maple Leaf Wrestling website has a terrific look at what the TV schedule looked like for a Saturday afternoon in Toronto in 1981.
Fans there sure were lucky to see a wide variety of wrestling including the local Maple Leaf Wrestling show, plus Mid-Atlantic Championship Wrestling, AWA, WWF, and more!
During these years, promoter Frank Tunney was booking a lot of talent for the Toronto shows from Jim Crockett Promotions based out of Charlotte, NC. Toronto fans got to see the "Mid-Atlantic Championship Wrestling" show which aired on channel 4 WIVB out of Buffalo, NY, just across Lake Ontario. Many of the Crockett stars also appeared on "Maple Leaf Wrestling" as well.
Take a look at the post on Andrew Calvert's excellent Maple Leaf Wrestling. Andrew gives some great detail with what it was like to be "pinned to the couch" on a Saturday afternoon in Toronto.
