On October 17, 2008, the CRTC approved an application by John Charles Yerxa for a new FM radio station in Edmonton, which would feature a "diverse" format of new popular music aimed towards teens and young adult demographics.

[3] On December 21, 2011, the CRTC approved the sale of CJNW-FM from Yerxa to Harvard Broadcasting of Regina, Saskatchewan, making it a sister station to CKEA-FM.

This prompted that station's current owner Corus Entertainment to file a trademark lawsuit against Harvard in October 2019, alleging that CKPW's branding and imaging was deliberately intended to trade upon the goodwill of the "Power" brand, including use of a similarly-designed black and white logo, and use of a nearly-identical catchphrase for its "phrase that pays" promotion.

[7] On November 18, 2019, a Calgary court approved an injunction by Corus Entertainment, ordering Harvard to cease using the "Power" name or any variation of it.

Harvard stated that it would not attempt to continue pursuing the matter in court, and planned to seek suggestions for a new name from listeners (who would also be entered in a contest to win $1,007).
