was given to Télé-Métropole (CFTM-TV); that station opened in 1961 and became the flagship of the TVA television network. 1968 to 1992 In 1968, CKVL abandoned its variety format in favour of a hybrid talk/music format, with weekday daytime programming being all-talk with a high proportion of open-line shows, including the famous Jacques Matti / Hélène Fontaine duo and former Liberal (and future Social Credit) politician Yvon Dupuis as morningman. Music programming mixing Top 40 hits with Adult contemporary music completed the schedule. The proportion of talk shows would increase over the next years, but at least some music would remain until 1999. Sister station CKVL-FM started its own programming in 1970, using an automated oldies format. New efforts by owner Jack Tietolman to get a television licence failed again in 1974. A licence was attributed by the Canadian Radio-television and Telecommunications Commission (CRTC) to another group (Télé Inter-Cité Québec Ltée), which managed to go bankrupt before even getting the station on the air. That same year, CKVL introduced all-news programming for its AM and PM drives (using respectively the names "Québec-matin" and "Québec-soir"), but high costs and less-than-satisfactory results provoked the end of that experiment the following year. A long labour strike affected programming in 1976. CKVL also officially became a unilingual French station that year, as the CRTC forbade bilingualism on privately owned radio stations (unless a station would get a special dispensation). Starting in 1978, CKVL started to lose money, due to declining listening combined with high labour costs. After being one of the most listened-to stations in Montreal in the 1950s and 1960s, strong competition from CKAC (and to a lesser extent from CJMS and FM stations) combined with the station's signal being inaudible at night in many parts of the Montreal market due to urban sprawl, resulted in a long decline in BBM ratings which would, along with corresponding financial losses, last until 1990. In 1979, CKVL tried to replace its Top 40/AC music programming with country music. That experiment failed and country music was later replaced with the "Solid Gold" concept, initially mixing current hits with oldies and subsequently moving to a more traditional oldies format. In 1981, CKVL committed a famous April Fool's hoax as it claimed that Prime Minister Pierre Trudeau had announced his resignation, and got an imitator posing as Trudeau to do an "exclusive interview" in which "Trudeau" claimed he
