The Beachcombers (a lot of people all across the country were upset when this was canceled, and for various insanely stupid reasons it's never been available on DVD. CBC and the other people/companies that own some or part of it would make a nice bit of money if they would offer it for sale.)
Loved this one while growing up. There have been a few attempts over the years in bringing it back, like that TV movie from about 5 years ago that included Dave Thomas. It was supposed to be a pilot to a revival series.
Agreed about Air Farce. By the time they brought in the younger people, it had become a tired show. The attempt to make it more relevant only showed how out of touch it was. Their New Years specials are still fun to see, though, but at times I still feel they really miss the mark. When they also renamed the Chicken Cannon to the F-Bomb was a mark of when things really started to change for the worst. This year's though I thought was pretty good, with some real laugh-out-loud moments.
In general though, good list!
My own Canadian list:
Littlest Hobo: Very low budget series that launched a lot of careers. When they announced that it would be returning to TV, I was disappointed to hear that it would only be the set from the 80's. It was a show that had originally begun in the 60's. With a low budget, they could easily make a new one, just like they've made many versions of Lassie.
Danger Bay: I guess I'd consider this a sister series to Rainbow County in your list. Had a similar environmental slant to Beachcombers. Though I do guess it had a long enough run (1984-1990).
Seeing Things: The little I've seen of this show, I've loved it. This was series on CBC about a journalist who'd have strange visions that would help him solve crimes. There was something about the acting in this that felt quite raw and natural. The theme song also was quite good. 'Cos I'm seeing things, believe me! I've never seen before! 'Cos I'm seeing things, deceive me, Like when you're walkin' out the door, I couldn't believe my eyes !!!
Strangely, no DVD of this show is available either. Lots of Canadian series seem to be lost to time, it seems. Would love to see a reboot.
