CFVO-TV is a defunct television station that broadcast from Hull, Quebec. It was the immediate predecessor to today's CHOT-TV, and launched on September 1, 1974 under the ownership of a company known as La Coopérative de Télévision de l'Outaouais. CFVO transmitted on channel 30, broadcasting mostly TVA network programming with various local shows.
The station lost a lot of money in its venture and, as a result, CFVO went bankrupt and left the air on March 29, 1977. The station's facilities were subsequently acquired in April by Télé-Québec, while SRC station CBOFT picked up a secondary affiliation with TVA until CHOT-TV went on the air in 1978.
The channel 30 position has since been occupied by Télé-Québec's CIVO-TV. Until that station signed on, that channel position was dark for a period of time, making CFVO the first major television station in Canadian history to have actually gone dark, and the only one until CHCA-TV in Red Deer, Alberta and CKX-TV in Brandon, Manitoba closed in 2009 along with three stations in 2011 — CJAL-TV Edmonton, CIAN-TV Calgary and CKXT-DT (formerly CKXT-TV) Toronto. All other defunct stations in Canada became repeaters of other stations almost seamlessly.
