Probably not what comes to mind first for most people when they think of quality Canadian TV, but this was god damned appointment viewing for me when I was 8
Before my time, back in its 60s and 70s heyday, I believe it was all Southern Ontario content. But by the time it was coopted by the WWF I think they just spliced in a match or two from Maple Leaf Gardens (or the arena in Guelph, Oshawa or who knows where) into all the American stuff to meet the CanCon requirements, along a few interviews with the legendary Hamiltonian Billy Red Lyons, there to pump up the combatants in whatever upcoming match was coming to an arena near you
