Whatever it's called I saw it about fifteen years ago on the CBC, late night. The premise is, at least the way I remember it, and I did join the flick in progress, a T-shirted, beer drinking, bearded male in his thirties plays and narrates home movies live-to-film.
We hear his French-Canadian-inflected voice: The man talks a bit as he changes reels on the Super-8 film projector; when the film is threaded he starts the projector. We see the lab-spliced Kodak white film leader run, and a few seconds later, just like the real deal, we have 'picture'. This happens a few times throughout the movie.
This proud researcher admits that he has come up empty handed. (I also admit that my efforts have been perhaps cursory at best.) Any help identifying this Canadian unknown classic would be much appreciated.
