CHOM-FM is an English language radio station located in Montreal, Quebec, Canada. Owned and operated by Bell Media, it broadcasts on 97.7 MHz from the Mount Royal candelabra tower, with an effective radiated power of 41,200 watts (class C1) using an omnidirectional antenna.

The station has a mainstream rock format since the station started using the brand name CHOM, and is sometimes pronounced /ˈʃm/ shoam as if it were a French word, but other Bell Media Radio personalities have also pronounced it as /ˈɒm/ chom.


Early years (1963-1974)[edit]

CKGM-FM, as the station was originally known, was founded by Geoff Stirling as a sister station to AM station CKGM, and opened on July 16, 1963. After a few weeks as a simulcast of CKGM, CKGM-FM launched a beautiful music format on September 1, 1963.

On October 28, 1969 CKGM-FM changed its format to album-oriented rock. The first song played after the format switch was Richard Strauss' "Also Sprach Zarathustra", followed by The Beatles' "Here Comes the Sun".[1] The station would change its call sign to CHOM-FM almost two years later, on October 19, 1971.[1]

Going bilingual (1974-1977)[edit]

In 1974, CHOM-FM proposed to the Canadian Radio-television and Telecommunications Commission a plan in which the station would become bilingual (English/French). The CRTC accepted this plan but only on an experimental basis that would last three years; it also blocked a plan to implement quadraphonic broadcasting. In 1977, the station was forced by the CRTC to opt between the two languages, and after considering becoming a French-language station, it finally reverted to English full-time.

Rise and fall and CHUM takeover (1979-2002)[edit]

CHOM-FM became increasingly popular, and in 1979 surpassed sister station CKGM in Bureau of Broadcast Measurement ratings. Both stations were sold to CHUM Limited on August 20, 1985.

Promotional bumper sticker distributed in the 1990s by CHOM-FM with its 1990s logo (an updated version of the 1980s cursive logo). Logo facelifts were made in the 1990s until its retirement in 2002.

The station acquired the rights to the syndicated show by Howard Stern which made its debut on CHOM-FM on September 2, 1997 amid much controversy as he launched himself on his very first show heard in Montreal in an anti-Francophone/anti-French tirade. His show was cancelled a year later, on August 27, 1998, after numerous complaints to the CRTC about politically incorrect remarks interpreted by complainants as sexist and homophobic.

Return to their classic rock direction and Standard Radio takeover (2002-2007)[edit]

2002 - 2010

Effective in January 2002, the station was sold to Standard Broadcasting, which already owned CJAD and CJFM-FM in Montreal, in exchange for Standard's CFWM-FM in Winnipeg.

Astral takeover and new direction (2007-2013)[edit]

Ownership changed hands again when on October 29, 2007, Astral Media took control of Standard Broadcasting and its assets.

On October 19, 2010, CHOM-FM celebrated its 40th anniversary as a radio station.

On June 22, 2011, it was announced that Terry DiMonte will be making a return to the station, however it is unlikely that he and Ted Bird will reunite on air.[2]

Bell Media[edit]

On July 2013, Astral Media was acquired and dissolved by Bell Media. [3] CHOM-FM has been reunited with its original AM station CKGM which CTV Globemedia (now Bell Media) acquired from CHUM in 2007.

Branding history[edit]

1963-1971: CKGM-FM
1971-1980s: CHOM-FM MONTREAL (with logo having a heart in a circle)
1980s: chom 98 ROCK
1990s-2002: chom 97.7 fm
2002–Present: CHOM 97-7 (even since logo change in 2010, the branding is unchanged from 2002.)


When first launched in 1963, CHOM-FM (then known as CKGM-FM) was originally based at 1455 Drummond Street in Montreal alongside the AM CKGM. Like CKGM, it moved to Westmount in the late 1960s at 1310 Greene.

In 1972, CHOM relocated to 1355 Greene, while CKGM opted to stay at 1310 Greene right across the street. CHOM eventually returned to CKGM's building a few years later and remained located there until its acquisition by Standard Broadcasting in 2002. At this point, CHOM-FM was moved to 1411 Du Fort street in Montreal (the building of Standard's other two existing Montreal radio stations, CJFM-FM and CJAD).

In September 2012, Astral Media relocated its city's English language radio stations (including CHOM-FM) with its French language radio stations at 1717 Rene Levesque East in Montreal.
