One really odd thing about Canada is we don't "naturally" produce enough content for broadcasters to meet their Canadian content requirements (let alone content people actually want to consume), therefore there are HUGE subsidies in place for the production of Canadian content - like billions of dollars a year huge. These subsidies enable broadcasters to pick up Canadian shows cheaply in order to meet their quotas. Most Canadians don't realize how much money is given to media creators because the money is distributed in many different forms from different institutions, at both the provincial and federal level, i.e. those which invest in media (http://telefilm.ca/) distribute tax credits (i.e. http://www.omdc.on.ca/ ), and so fourth. This is ignoring the CBC by the way, the government financed broadcast organization.
The subsidies haven't followed changes in Canadian media consumption patterns though, meaning we over-subsidize mediums which are consumed less and under-subsidize those that are consumed more. It will be interesting to see if / how things change moving forward.
