I grew up close enough to the border to watch Canadian and US television all my life, and in college (Western WA U in Bellingham) that was the only tv that came in well on antenna, so I remember seeing Canadian commercials. By the time I was in college Star Trek had already been and gone, and maybe Shatner was looking for a little support on the side. Perhaps Little Hawk will bring his encyclopedic knowlege of the man into this thread and give us an answer.
