CFZM is a Canadian Class A clear-channel radio station, licensed in Toronto, Ontario, which airs at 740 kHz and in downtown Toronto at 96.7 FM. The station airs a pop standards format branded as Zoomer Radio, with the slogan "Zoomer Hits". Its studios are located in the Liberty Village neighbourhood, while its transmitter is located in Hornby.
CFZM is the only remaining adult standards-formatted station in North America that broadcasts a 50,000-watt clear channel signal. Like most clear channels in this region, CFZM's nighttime signal can be heard in all of the eastern half of North America, dependent on atmospheric conditions. CFZM and WSM are the only two remaining clear channel stations that primarily broadcast music.
CFZM's daytime signal can be heard in most of the Ontario Peninsula, as far west as the Michigan Thumb, and as far east as Syracuse, New York. Its signal strength allows it to have an audience in nearby cities such as Buffalo, New York and Erie, Pennsylvania, where local standards stations have gone defunct.
The station was originally launched in 1956 on 1250 AM in Oakville, with the call sign CHWO, by Prime Time Radio, a company owned by broadcaster Howard Caine and a number of minority investors. In 1967, shortly before Caine's death, his wife Jean was appointed to the board of directors and took over the station's management.
In 2000, after the Canadian Broadcasting Corporation's CBL gave up its longtime home on 740 and moved to FM. CBL had long been plagued by radio frequency interference that made it virtually unlistenable in downtown Toronto. Despite this shortfall, the prized clear channel frequency became hotly contested by new and existing stations in the area. CHWO applied for the frequency, citing that it could provide a stronger service to the region's older adult population. Concurrently, the Caine family also applied for a new station on the old 1250 frequency, to air a Christian music format. The applications were granted, and CHWO moved to the 740 frequency on January 8, 2001, leasing CBL's former transmitter in Hornby from the CBC. CHWO originally applied for the new call sign CFPT, but when this was denied by Industry Canada because the call sign was already in use, the station chose to retain its heritage CHWO calls. CHWO's replacement at 1250, CJYE, launched on February 5.
On September 18, 2007, Prime Time Radio announced a deal to sell the station to Moses Znaimer, under whom it would become a sister station to Toronto's classical music station, CFMZ. The deal was approved by the CRTC on March 31, 2008. Znaimer also moved the station's studios and city of licence to Toronto, and changed the station's call sign to CFZM on July 22, 2008.
Under Znaimer's ownership, the station's program schedule now includes a daily talk show, airing from 12pm to 1pm, originally hosted by consumer advocacy journalist Dale Goldhawk and now hosted by Libby Znaimer. The station played a "traditional" nostalgia music weekday evenings on the show Sentimental Journey and on some weekend specialty shows, and caters principally to listeners over 40 years of age. Other personalities associated with the station have included television and radio sportscaster John Gallagher and former MuchMusic VJ Ziggy Lorenc.
Monday through Thursday nights, CFZM carries three late-night speciality programs: Theatre of the Mind (10PM to 11PM Eastern time), rebroadcasting in their entirety classic shows from the "Golden Age of Radio"; Stardust (11PM to 12AM Eastern time), an hour of romantic music; and Midnight Blue (12AM to 1AM), an hour of "raunchy" music that CFZM promotes as "the only X-Rated radio show" (in truth, some of the lyrics are raunchy and suggestive, but most listeners would not consider them "X-Rated").
CFZM also carries two weekly shows featuring 1950s/1960s oldies music, Friday Night Bandstand (7PM to 1AM Eastern time, focusing more on the 1950s and early 1960s, with fewer post-1964 songs) and The Heart and Soul of Rock 'n Roll (7PM to 1AM Eastern time on Saturday nights, focusing more on music from 1964 to the early 1970s, although some 1950s and early 1960s hits are heard).
Weekends on AM740 are an eclectic mix of informative programming and specialty music shows. A complete list of programs with descriptions can be found on the shows page of the website.
The station was originally owned by Znaimer's privately held MZ Media Inc. As part of a reorganization of Znaimer's media assets, the station was transferred to the publicly traded ZoomerMedia in 2010.
In 2012, Zoomer Media was one of 27 applicants for an FM station at 88.1 MHz, for the purpose of simulcasting CFZM in the city of Toronto itself. The bid was unsuccessful and the CRTC awarded the frequency to CIND-FM.
On April 27, 2015, MZ Media received CRTC approval to operate a nested FM transmitter in downtown Toronto to rebroadcast CFZM at 96.7 MHz with an average effective radiated power (ERP) of 22.4 watts (maximum ERP of 82 watts with an effective height of antenna above average terrain of 280.1 metres), with transmitting facilities located atop First Canadian Place. The repeater (CFZM-1-FM) would enable CFZM to overcome the deficiencies of the AM signal in the downtown core—the same problems that led CBLA to leave the AM band 15 years earlier. The repeater, however, will be a first-adjacent signal to CKHC-FM 96.9, a college radio station at Humber College that serves an area in the northwestern part of the city, as well as having co-channel interference with CHYM in Kitchener and CJWV in Peterborough. The repeater would sign on that July.
