If everyone starts watching all their TV on Netflex and similar services, Canadian TV could all but disappear.
Speaking as a proud Canadian, I say: Good. That's called the power of the free market.
I have no doubt that 90% of Canadian content producers would shrivel up and die without CRTC protection. I also have no doubt that the survivors would adapt, improve, and make shows that people actually want to watch, possibly even opening up an export market for Canadian content.
Any time the government protects cultural content, the quality of that content plummets because there's no free market competition to keep producers sharp.
Government can help content producers with strategic investments. TV Ontario produces far superior shows to the CBC with a fraction of the amount of government investment and in a commercial-free environment. The CBC needs to go commercial-free and concentrate on making decent shows, not copycat shows of American crap.
