The construction of CKAC was announced on May 3, 1922, by daily newspaper ''La Presse'', which created the station and owned it<ref>Pierre Pagé (2007). ''Histoire de la radio au Québec'', Fides, Montreal, p. 27</ref> until 1969. On-air testing began by mid-September 1922,<ref>Bernard Montigny (1979). ''Les débuts de la radio à Montréal et le poste CKAC'', M.A. thesis, [[Université de Montréal]], pp. 21-22, 26.</ref> and the station was officially inaugurated on October 2,<ref name="usherb">[http://bilan.usherbrooke.ca/bilan/pages/evenements/344.html ''Ouverture officielle de la station radio CKAC'', Bilan du siècle, Université de Sherbrooke.]</ref> although regular programming had already begun on September 27.<ref>Montigny (1979), op. cit., p. 22.</ref> CKAC was the first [[francophone]] radio station in North America.<ref name="usherb"/>

CKAC was broadcasting on 730&nbsp;kHz right from the start, but it originally shared the frequency with CFCF (later [[CINW]]) and [[CHYC (AM)|CHYC]] until 1929, at which point CKAC became the only station on that frequency.<ref name="page451">Pagé (2007), op. cit., p. 451.</ref> Power was increased to 5,000 watts (full-time) on October 19, 1929, using a new transmitter site located in [[Saint-Hyacinthe]].<ref name="page451"/> CKAC applied to increase its power to 50,000 watts the following year, but this application was denied by government authorities.

The station became an affiliate of the [[CBS]] network in 1929. This affiliation was established to broadcast concerts from renowned American orchestras on CKAC. CKAC also created its own orchestra that year, which would produce concerts aired on American stations twice a week until 1933. (CKAC did keep its CBS affiliation until the late 1940s).

Radio dramas appeared on CKAC in 1931, and would continue to be heard for many years thereafter, until they were phased out as television was introduced and became popular.
