The National Film Board of Canada has been funding and encouraging motion picture creativity since 1939. No discussion about animation in Canada is complete without a mention of the NFB.
Their fantastic website includes a history of the bureau as well as an online catalogue of almost 1500 films, including 292 (to date) animated films. All are freely available to watch online for personal use. They offer customizable homepage and a handy "help centre" page for their content.
