CJRT-FM is a Canadian public radio station, which broadcasts at 91.1 on the FM dial in Toronto, Ontario. CJRT currently operates as JAZZ.FM91. The station transmits at a strength of 40,000 watts with transmitter facilities at the CN Tower. It is available on Bell TV as channel 960, and on cable FM and digital cable audio services throughout Ontario. In addition to streaming its on air programming, it supplies a second unhosted FM91 Oscar Peterson streaming channel. There is much repetition of the songs and the playlist for this channel is of limited value as it is not regularly updated and often displays a different song than that which is being streamed despite being refreshed. The station was founded in 1949 as an experimental FM broadcaster, only the second in Canada, by the Ryerson Institute of Technology (later Ryerson University). The JRT in the station's call sign stand for "Journalism, Radio, Technology", which were three of Ryerson's educational mandates.
