CTV's schedule always had more game shows that the other networks. In the mid '70s, they had about 6 or 7 daily games at one time.
Some have already been mentioned above, but others from that time included Celebrity Dominoes, Pay Cards, He Knows She Knows, Educated Guess and First Impressions (hosted by Alan Thicke).
Global had a few, including Going Places (hosted by Mike Darrow), Winners Circle, Opposite Opposite Sexes and Quiz Kids.
Syndicated at that time included I Saw That, Five of a Kind, Party Game and Know Your Sports, to name a few.
There was another surge in the mid-80s, that saw shows like Guess What and Talkabout premiere, while shows like Definition and Mad Dash were still going strong.
