Murray Schafer as guests of Governor General Jules Leger at Rideau Hall in the autumn of 1976 to discuss and formulate a policy for the arts and culture in Canada.
, the head of the National Film Board of Canada, asked Malcolm Ross to become the Head of Distribution at the NFB in 1942. There Ross's job was to supervise the distribution of all NFB productions, both theatrical and nontheatrical. This included rural, industrial, and trade union circuits, the preview library, and relations with volunteer projection services. He was also responsible for all foreign distribution and the translation of Canadian films into the leading European languages. He was also involved in advising the making of many propaganda films and, therefore, got to know directors such as Joris Ivens who did Action Stations and Corvette Port Arthur for the NFB. The Academy of Motion Picture Arts and Sciences awarded a special Oscar for the work that the NFB did during World War II. In 1945, when Grierson was preparing to leave the NFB, he suggested Ross as one of three possibilities for his replacement; however, Prime Minister William Lyon Mackenzie King decided instead to downsize the NFB since the war was over.
