The Trans-Canada Microwave System

On 1 July 1958, the Trans-Canada Microwave System introduced live network television and direct-dialled long distance telephone service to Canadians from coast to coast. Comprising 139 towers spanning more than 6275 kilometres, it was, when completed, the world's longest such network. Later extended and upgraded, the system had an immense impact on Canada's society and economy. Although the achievement has been recognized as one of the most important in the history of Canada and is prominently mentioned in most histories of telecommunications in Canada, a detailed account of its design, construction, and impact has never been prepared. The passing of most of the participants and a lack of primary source material will make preparation of such an account a daunting task going forward.
