CFGX-FM is a Canadian radio station, which broadcasts at 99.9 FM in Sarnia, Ontario. The station broadcasts an adult top 40 format with the brand name The Fox and slogan Today's Best Music.
CFGX-FM can be heard in the eastern parts of Michigan as far west as Lapeer and well into the Thumb region, and used to have a listenable signal in much of Macomb County before Detroit's WCHB (now WMUZ) signed on an FM translator at 99.9 (which now relays WDMK-HD2). The station can be heard as far east as Strathroy (farther east, co-channel CHJX-FM in London interferes) and Chatham to the south.
