After 26 years as a country station, CFGM changed its format and call letters at 5 p.m. on June 29, 1990, broadcasting a [[rock music|rock]]-leaning [[contemporary hit radio|Top 40/CHR]] format as ''AM 640 The Hog'', CHOG (which would later shift towards a more mainstream direction in September 1991).<ref>Greg Quill, "Nobody waved goodby to CFGM," ''The Toronto Star'', July 2, 1990.</ref><ref>{{cite web|url=http://rockradioscrapbook.ca/cfgm-farewell-jun29-90.mp3|title=Farewell June|website=rockradioscrapbook.ca|access-date=20 June 2023}}</ref> By early 1992, the station rebranded as ''AM 640 The Beat Of Toronto'', and adjusted its format to [[Rhythmic contemporary|Rhythmic CHR]].<ref>Greg Quill, "CHFI's music mix catches ears of 208,700 more listeners," ''The Toronto Star'', January 31, 1992.</ref>

Several notable radio personalities were associated with the station during this era, including John Gallagher, "Tarzan Dan" Freeman, Pat Cochrane, Adrian Bell, Tony Monaco, Deanna Nason, Randy Taylor, Eric Hollo, Kenny 'The Hitman' Caughlin, Roger Kelly and the Toronto radio team of [[Jesse and Gene]]. After [[CFTR (AM)|CFTR]] changed formats from contemporary hits to [[all-news radio|all-news]] in 1993, CHOG was the last Top 40 station in the Toronto [[media market|radio market]] until [[CKIS-FM|CISS-FM]] adopted the format in February 1999. Talk shows would later come to take up a substantial part of the station's schedule, particularly during midday periods when many of the station's hit music listeners might normally be in school.
