I should have remembered that myself! The CBC plant in Edmonton had only mono output feeders, but could receive stereo programming from what we then still called the "FM Network" (later CBC Stereo, later Radio Two). Programs that were produced there such as RSVP, which I hosted, were fed to the Mono network but sometimes the tapes were shipped to Toronto or elsewhere, and mono with butterfly heads was pretty close to full track.

That was the place where we had no leader tape, so the people in Current Affairs would just take a piece of blank tape and thread it in backwards and cut it in as leader. Much fun when the tapes were reused.
