much of the 1970s was in the field of voice acting with many major television productions like Rudolph the Red-Nosed Reindeer and Spider-Man sporting Canadian voice actors like Paul Soles and Paul Kligman. Some of the animation for these features were sub-contracted by such Canadian studios as Crawley Films in Ottawa and The Guest Group in Toronto, a group of creative companies owned and run by Al Guest. The situation began to change in the late 1960s with Rocket Robin Hood, which was produced by Al Guest. 1970s-1980s In the 1970s, independent companies were formed to produce low budget children's programming. Some examples are The Undersea Adventures of Captain Nemo, and The Toothbrush Family as well as Ukaliq and The Sunrunners all written, produced and directed by Al Guest and his partner Jean Mathieson at their Toronto company Rainbow Animation. Longer term successes began with the establishment of the Canadian animation studio Nelvana Limited in 1971. Before they were huge, they mainly did the production for live-action/animated shorts.

Because of the failure of Rock & Rule, Nelvana almost shut down operations and would file for bankruptcy. To save themselves from shutting down, the company turned to television animation work which proved successful with series like Inspector Gadget and Care Bears. The company eventually became a prime supplier of animation work into the American network TV market throughout the 1990s. Two new players suddenly appeared in Ottawa, with Atkinson Film-Arts producing TV specials based on the Jean De Brunhoff Babar books and the Lynn Johnston comic strip For Better or For Worse, as well as the series The Adventures of Teddy Ruxpin, Dennis The Menace, and animation for the film Heavy Metal and the specials and subsequent series of Kevin Gillis' popular The Raccoons. Disputes between Atkinson management and the Raccoons producers led Gillis' Raccoons production partner Sheldon
