This paper examines the history, functions, and impact of the four existing educational communications organizations in Canada: (1) TVOntario; (2) Radio Quebec; (3) ACCESS Alberta; and (4) the Knowledge Network of the West in British Columbia. It is noted that, while broadcasting and communications have always fallen under federal jurisdiction, education is the sole responsibility of each provincial government. The overlap between these two, in the form of educational broadcasting, necessitated the formation of new regulatory policy. A discussion of the new policy reveals that, while the four authorities may share similar purposes in the provision of educational opportunities to the public, and adhere to a common national programming definition, there are distinct differences among them that are reflected in their roles and functions: (1) TVOntario produces and distributes all educational programs on its television network; (2) ACCESS Alberta (Alberta Educational Communications Corporation) produces educational programs and operates radio stations, but has no television network of its own; (3) Radio-Quebec distributes educational programming and produces programming relevant to the region's cultural concerns; and (4) the Knowledge Network distributes programming produced elsewhere. It is noted that the Agency for Tele-Education in Canada (ATEC) is an umbrella organization designed to facilitate interaction among the four educational communications authorities, including communication, information sharing, and co-production of programs. This report provides a brief introductory overview of the four communications organizations together with a detailed description of each of the four. (17 references) (DB)
