As of Feb 28, 2021, CBX is the 3rd-most-listened-to radio station in the Edmonton market according to a PPM data report released by Numeris.

[2] It was the third of three 50,000-watt Trans-Canada Network AM radio stations to sign on in the Prairie Provinces (the others being CBK in Saskatchewan and CBW in Manitoba).

[7] Under the new setup, CBX was reoriented to be Edmonton's CBC station and took over CBXA's frequency of 740 kHz from a newly-constructed 50,000-watt transmitting site near Beaumont.

On March 16, 2006, the Canadian Radio-television and Telecommunications Commission approved the station's application to add a nested FM transmitter at 93.9 MHz in Edmonton to simulcast the AM programming.

The last few BBM radio ratings measurements have shown CBX steadily climbing in audience share in Edmonton.

As of the spring 2009 BBM measurement, CBX is the second-most listened to radio-station in Edmonton, behind news-talk radio station CHED.
