Why the Transition?
Following a decision from the Canadian Radio-television and Telecommunications Commission (CRTC), many Canadian local television stations have stopped broadcasting over-the-air in analog and are broadcasting over-the-air in digital as of August 31, 2011.
The vast majority of Canadians are not affected by the transition to digital over-the-air television because they receive their TV signals via cable, satellite or the Internet. If you receive TV signals using an outdoor antenna or "rabbit ears", you may be affected.
Why Digital Broadcasting?
Digital signals provide better picture and sound and take up less airwave space. The freed up space will be used for other purposes like advanced wireless and public safety services, such as those used by police and fire departments.
