WNED and WBFO are carried on cable in the Toronto area. There's significant reach there and they derive significant money from Canada's biggest city and the "Golden Horseshoe" at the western end of Lake Ontario.
I have to ask. Do you mean the RF signal is carried over the coax cable that someone is supposed to screw onto the back of their home stereo receiver to receive the station on the FM tuner? I know some cable systems did this during the startup years and there was extremely low public awareness of it but I assumed it was deprecated decades ago, especially since cable is all fiber and digital now.
Or do you mean someone in Toronto has to tune to a particular TV channel that carries an audio-only feed of the radio station and listen to it on their TV?
