# In Australia, the government originally planned a switch-off in 2008. This has now been delayed to a "to be determined" date in 2010-2012. Until that time, free-to-air stations will be simulcast, along with digital only channels like ABC2. Since 1999, regulations have required that all locally-made free-to-air television shows be in 16:9 widescreen format. Cable Television Networks began broadcasting in simulcast from 2004 and analogue cable services were switched-off in June 2007.

# In Canada, the main free-to-air broadcasters (Canadian Broadcasting Corporation, CTV, and Global) have launched HD streams of their programming. Originally, unlike in the other countries, Canada was allowing the market to determine when the analogue switch-off begins. As a result, currently analogue and digital broadcasts co-exist, with virtually the only way to receive digital TV in much of the country via cable or satellite TV. However, in some urban areas like Toronto, it's also possible to pick up DTV over-the-air, though as of May 2007 there are less than 20 digital television stations in Canada. On May 17, 2007, the Canadian Radio-television and Telecommunications Commission (CRTC, Canada's broadcasting authority) ruled that television stations would indeed be forced to switch to ATSC digital broadcasting by the end of August 2011, and that analogue NTSC channels must then be dropped, except in remote and northern regions where analogue transmission may continue for an undetermined period.(Wikinews)
