In 1925 or 1926, CFYC entered the final phase of its life under the International Bible Students Association, which later became the Jehovah's Witnesses. As a boy, John Avison played the piano for Bible Students' programs at a studio on Hastings Street. JOHN AvtsoN: I used to be amused by the fact that the manager of the station was a man with, I think, not a suitable name for a radio station manager: his name was W. J. Tinney. They had a group called "The Choir of a Million Voices." Of course, they couldn't accommodate a million voices, but this was premised on the fact that they sold the hymn books. They assumed that everybody who bought a hymn book, all across the country, would be joining in. I played the piano for the choir and played solos. The religious part, outside of playing for the choir, was not part of my knowledge of the station at all. CFYC moved out of the building on Hastings Street to a very large house on Kingsway near Central Park [in Burnaby]. I think that was just about the end of the operation of the station. In addition to CFYC, the International Bible Students Association was also operating radio stations in Edmonton and Saskatoon and two stations in Toronto. These stations were the focus of a dispute that had a profound effect on the future of Canadian broadcasting. In 1928, the Department of Marine and Fisheries refused to renew the licences of the IBSA stations on the grounds that the Bible Students were using the airwaves to attack other religious groups. Although the government was acting in response to complaints from the public, the number and credibility of the complaints received were questionable. The only significant case of defamatory broadcasting involved two anti -Catholic lectures by a Ku Klux Klan spokesman who had purchased time on the Saskatoon IBSA station. Nevertheless, the licences were not renewed. CFYC Vancouver and its sister stations went off the air in March 1928. The whole issue was vigorously debated in Parliament and in the press. The government was accused of religious discrimination in the matter, and received a tide of letters and petitions in support of the Bible Students. The controversy led, in the same year, to the creation of a royal commission on Canadian broadcasting led by Sir John Aird. The Aird Commission's recommendations pointed the way to the establishment of the CBC some years later.
