The majority of Canadians will not be affected. If you receive your TV signals by cable, satellite or another TV service, the switch to digital will not affect you. You will continue to receive your existing television services with the equipment that you currently use. You will not be required to buy a new TV or other equipment, or subscribe to additional services.
The switch to digital may affect television viewers who receive local over-the-air TV stations using an outdoor antenna or “rabbit ears”. Once the switch occurs, these viewers may need to have either a digital converter box or a television with a digital tuner, or may want to consider receiving their TV services from a cable, satellite or other service provider. If you decide to purchase a digital converter box, consider purchasing one with the analog pass-through feature. This feature enables the viewing of both digital and analog signals which may be important for viewers that will receive both types of signals.
