The reason that DTV never caught on in Canada was because of how the Canadian Radio-television and Telecommunications Commission (CRTC), Canada's FCC equivalent, handled the licenses: they required the stations to file amendments to get permission to carry digital subchannels. The Canadian TV station CFTV-TV 34 of Lamington, Ontario has three subchannels. Like the United States and Mexico, Canada uses the same ATSC technology, but the way Canada uses it is underwhelming.It is perhaps impressive if you come from Canada where DTV never really caught on, but there's a dark side to the technology where stations carry multiple HD channels or more than six SD channels and it all looks (and sometimes sounds) like a bad dream.
Then there's the observation that all of these channels don't necessarily bring much in the way of variety or fresh content. In many cases, something that was once to die for leaves to make way for something else. The re-branding thing has gone on for too long.
