In some locations, primarily national parks, provincial parks and remote communities with little or no local media service, a transmitter operated by the Canadian Broadcasting Corporation carries the service on a standard AM or FM broadcast frequency. As of August 2007, most of these AM and FM transmitters were unlicensed by the CRTC under a special license exemption granted to low-power non-commercial broadcasters.Broadcasting Decision CRTC 2007-280, August 7, 2007.
