O Canada was a Canadian-American animated television anthology series, broadcast in the United States on Cartoon Network. O Canada was the first Canadian cartoon to air on Cartoon Network. Shown mainly on Sunday nights at 12:00 midnight ET, O Canada featured a selection of animated shorts from Canada, mostly from the archives of the National Film Board of Canada. The title of the series originated from the name of Canada's national anthem, O Canada. One of the notable shorts featured in this series was Bob's Birthday, which would later serve as the basis for Comedy Central / Global Television Network's Bob and Margaret series, which would debut the following year. Despite its time slot, Bob's Birthday was censored with one scene, that featured Bob fully bottomless, edited with a maple leaf electronically superimposed over his genitalia.
