There is a more sinister aspect to this consolidation of news media in a few hands. Starting in the 1990s, the Canadian national archives were purged of an extensive collection of small and medium sized publications in order to "save space" in the times of austerity. This means few Canadians, even if they bothered, can now not find out about the extent and diversity of media options they once had even just 15 to 20 years ago. 

Canadians also experience one of the highest levels of search engine censorship in the developed world. You can do an easy experiement to check this out: just take a holiday in another country and then do searches on Canadian themes etc.: the results you will find vary greatly from what you get inside Canada (mostly images of people playing hockey, etc.). 

Canadians are kept in a (deliberate) media bubble and fed mainstream news (CBC etc.) in the hopes they keep their horizons very narrow and centered around hockey, holidays and commuting.
