The CBC Channels & Frequencies Guide will provide you with the location of the closest over-the-air CBC transmission tower in your area.
When Canada made the switch from analogue to digital television transmission, we weren’t able to replace all of the towers in our system to create the same over-the-air network that existed for analogue transmission, which has been decommissioned.
In the end, CBC/Radio-Canada installed a digital transmitter for every one of its television production centres for a total of 27 transmitters across the country (14 for CBC and 13 for Radio-Canada). Each tower costs in excess of $1 million and there are no plans now to add more to the existing footprint.
