Boom FM was first launched on May 1, 2003 as a network of French-language oldies stations, and originally included CFEI-FM and CHRD-FM. CFVM-FM and CFZZ-FM joined the network in 2005 after these stations were acquired by Astral Media from Corus Entertainment. All four stations previously had an adult contemporary format. Since Astral Media already has two FM stations in each of Quebec's larger markets, it is impossible for them under current Canadian Radio-television and Telecommunications Commission (CRTC) regulations to launch Boom FM stations in these markets without dumping either the NRJ or the Rouge FM format, both of which are very successful according to Bureau of Broadcast Measurement (BBM) ratings.
On December 26, 2009, Boom FM added its first English-language affiliate, CHBM-FM in Toronto, Ontario, which flipped from its longtime adult contemporary EZ Rock format (as CJEZ-FM) to adult hits under the boom 97-3 name. It is the only Boom FM station not using the classic hits format, though its logo uses the same lettering and 45 RPM plastic insert device as its Quebec counterparts. On June 30, 2011, Boom FM added its second English-language affiliate, CJOT-FM in Ottawa which flipped from the very same adult contemporary of the former CJEZ-FM Toronto as EZ Rock to the classic hits format as boom 99.7. The name "Boom FM" is a reference to baby boomers, who are the main target of the network.
Following Bell Media's approval in 2013 to acquire Astral Media, a condition was placed in which that it must divest itself of several television services and radio stations, including CHBM and CJOT, which were placed in a blind trust pending its eventual sales. CJOT would be sold Corus Radio in March 2013, while CHBM was sold to Newcap Radio in August 2013. Corus' acquisition of CJOT-FM was approved on January 31, 2014, while Newcap's acquisition of CHBM-FM is still awaiting CRTC approval; it is expected that the Boom FM branding will eventually once again be limited to two French-language stations in Quebec.

CKSM AM 1220 of Shawinigan was originally announced in April 2007 to have been a new affiliate of Boom FM, with plans to relocate the station to the FM band. However, the plans never materialised, and the station, which at the time was owned by Astral but rebroadcast then-Corus owned CHLN 550 AM of Trois-Rivières, closed down on June 30, 2007.
