Mrs. Maniatakos operated a closed circuit specialty audio service in Toronto since 1966 under the name
CHCR-FM. This service aired Greek language programming 24 hours a day. It was initially available as an
SCMO service (via
CKFM-FM) but subsequently switched to cable and was available on
Rogers Digital Cable channel 959, as part of their digital radio offerings, in Toronto and area. In 2007 when CHTO launched, CHCR-FM was discontinued and CHTO now airs in its place on Rogers Cable. The station was initially going to launch by the end of 2006, but this was pushed back due to technical problems. It has been on the air since . On June 10, 2009, CHTO applied to the
Canadian Radio-television and Telecommunications Commission (CRTC) to increase the daytime transmitting power to 3,000 watts, in an effort to serve communities in Mississauga and Brampton. The request received approval on November 5, 2009. CHTO began broadcasting at its new power as of March 2010. On December 4, 2012, the CRTC approved a change in ownership of the station to John Maniatakos due to the 2009 death of his mother, original owner Mrs. Maniatakos. ==CHTO-1==
