CKDX-FM (88.5 MHz, Hot Country 88.5) is a radio station licensed to Newmarket, Ontario, Canada and serving the Greater Toronto Area.

Owned by Evanov Communications (but with a 30% stake held by outside investors under numbered companies),[1] it broadcasts a country format.

On August 2, 1978, Bradley R. Walker, representing a company to be incorporated, was given approval by the CRTC to operate a new English language AM radio station at Newmarket, Ontario which would operate on the frequency of 1480 kHz with 10,000 watts day and night.

[2] The station was launched on February 28, 1980, as AM 1480 CKAN, broadcasting from 6 a.m. to midnight with a hybrid easy listening/beautiful music format.

In December of that year, the station adopted its current CKDX callsign with an oldies/easy listening format.
