CHAS evolved to a younger sound, moving the format to adult contemporary and adopting Lite 100.5 as the station's branding, later changing to Mix 100.

The arrangement, one of the first LMAs in the Canadian radio industry, took effect on August 31, 1992, with CHAS moving into CJQM-FM's studios at 642 Great Northern Road, where the two stations remain to this day.

Among the benchmarks of that time for the station, were reaching a weekly audience of 30,000 listeners and negotiating the broadcast rights for all Greyhounds home and away games away from the Sault Ste.

At this point, CHAS and 3 other Telemedia-owned stations in Northern Ontario adopted the "EZ Rock" format and branding patterned after Standard Broadcasting's CJEZ-FM in Toronto.

On July 4, 2011, CHAS altered its musical format, keeping the "EZ Rock" branding but presenting a more contemporary version of its AC Mainstream Plus blend.

CHAS, as noted above, was one of four EZ Rock-branded stations owned and operated by Rogers Media, all of which are located in Northern Ontario (the others being CKGB-FM Timmins, CHUR-FM North Bay, and CJMX-FM Sudbury).

[1] As of the fall of 2019, CHAS-FM and the other "KISS" stations had returned to a mainstream adult contemporary direction with a playlist spanning the 1980s to today's hits.
