"Boom" was first launched on May 1, 2003 as a network of French-language oldies stations, and originally included CFEI-FM and CHRD-FM.

It was 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.

In 2017, Stingray Radio gained permission from Bell Media to begin using the Boom brand and its content in Alberta.

CKSM AM 1220 of Shawinigan, Quebec was originally announced in April 2007 to have been a new affiliate of Boom, with plans to relocate the station to the FM band.

[7] Stingray's CHNO-FM in Sudbury, Ontario, CIJK-FM in Kentville, Nova Scotia, and CHHI-FM in Miramichi, New Brunswick are branded as Rewind instead of Boom, but otherwise resemble Boom FM stations with a similar logo design, a similar classic hits format and some shared programming.
