 In September 1984, CHQM began airing the "Music of Your Life" format from 6 p.m. to midnight daily while retaining its main easy listening format for the balance of its broadcast day.On January 1, 1990, CHQM dropped its longtime easy listening format for an adult contemporary format and began using the on-air brand Lite 1320.CHQM and CHQM-FM were purchased by CHUM Limited on October 17 that year, but due to Canadian Radio-Television and Telecommunications Commission (CRTC) regulations of the time (which allowed ownership of only one AM and one FM station in the same market), CHUM had to sell either CHQM or its other Vancouver AM outlet, CFUN; CHUM chose to sell CHQM.
