The three maps bear the following titles: 1. Carte I. Puissance et portée des postes actuels -- 2. Carte II. Etendues du Canada couvertes par les postes américains -- 3. Carte III. Etendue du pays qui serait couvert par un système national. These maps were prepared by the Canadian Radio League and published in a pamphlet entitled "La Ligne Canadienne de la Radio, But, Renseignements, Appui de l'Opinion Publique." The maps are intended to give support to the recommendations of the 1929 Royal Commission in Broadcasting, which proposed that a national broadcasting system be established, consisting of several 50,000 watt stations and supplementary local stations of lower power.
Map No. 1 gives the reception contours of existing Canadian stations of 1931. It is intended to show that only the areas of high population density are covered, and much of rural Canada is unserviced. Map No. 2 gives the reception contours for the coverage of Canada by American radio stations. Because of their proximity and high power many American stations penetrated deeply into Canada. This map is intended to show that all of populated Canada is covered by radio broadcasts originating in the United States. Map no. 3 is intended to show te feasibility of the Royal Commission's recommendation that a national broadcasting system be established consisting of seven 50,000 watt stations and four 5,000 watt stations, which together would cover most of populated Canada. The concentric circles represent the reception contours for these stations, the inner circle presumably delimiting the good reception areas and the outer circle the marginal areas.
These maps have been copied from a pamphlet loaned by Mr. Graham Spry, 446 Cloverdale St., Ottawa. An English translation of the pamphlet also containing maps is held by the P.A.C. Library: HE 8699 C2C272 1931. See also: Report of the Royal Commission on Radio Broadcasting: HE 9715 C 2A5 1929
