Radio antennae and their supporting structures are the most visible features of the physical manifestations of a vast network of mass-media, commercial and private radiocommunications systems which integrally affect the economic, social, political and cultural development of this country. Since the first two external antennae in Canada were approved in 1901, their number has steadily grown until there are approximately 230,000 licensed antennae in Canada today. Most antennae, whether licensed or licence-exempt, are sited (location, height, antenna system and tower type) with the fullest regard to the technical issues which affect their ability to radiate and/or receive radio signals. Traditionally, accorded rather low regard is the extent to which the antenna may negatively impact upon the community near which, or within which, it may be located. Despite the potential for negative health, safety and aesthetic impact, most antennae are sited with little or no objection from any quarter. Indeed, the history of the siting of broadcasting antennae in Canada is very much a study of local pressure for more, larger and more powerful facilities.

Recently, attitudes about the appearance and safety of the local environment have begun to change. Residents and municipal governments have started to demand that local interests be considered wit hin aut horizat ion processes when facilit ies which can negatively impact upon them may be located in their midst. Local and area land-use planning has evolved to a highly developed state. Today, almost all buildings, structures and facilities which are to be located within municipal boundaries are planned in advance and integrated into the community so as to minimize any undesirable impact.
