The Sharing of Radio Frequencies between Canada and the United States: the Case of AM Broadcasting
SummaryBecause of the physical nature of the radio spectrum, the sharing of radio frequencies between Canada and the United States is a necessary but delicate process. Using the example of AM broadcasting, the purpose of this article is to give an overview of the bilateral agreements concluded between the two countries during the last sixty years. Multilateral conventions, as well as agreements and arrangements, are also reviewed in order to permit an adequate understanding of the evolution of the bilateral relation. The review of those conventions also indicates the legal principles applicable to the sharing of frequencies for broadcasting purposes.From the initial chaos to “first come, first served” and, finally, to the “a priori” planning of the spectrum, the relative situation of Canada vis-à-vis the United States gradually improves. It is through the negotiation of technical agreements that Canada can obtain access to a natural resource necessary for the expression of its national identity and using a broadcasting system of its own.
