I already knew it was by Nelvana, and that they did all those other cartoons and animated adaptations, but I wasn't aware it was actually Canadian...
That's cool.
Well, its more of a collaborative effort between some French, British, and Canadian companies.
Nelvana
Ellipsanime (French)
Funbag Animation Studios
Television South (Season 1)
Scottish Television (Season 2 through 5)
Actually, the Rupert you are referring to with 5 seasons and made in America, was made in Canada by Nelvana, the same animation company known for the Care Bear s, Babar, Pippi Longstalking, Inspector Gadget and MANY other series.
