The answer to your question takes us back to the 26 or 27 objectives set out in the Broadcasting Act. Simply put, however, we have to make sure Canadians are able to express themselves on the public airwaves and, on the flip side, to hear and see that expression of themselves. What's more, mechanisms are needed to ensure everything comes together.
That is why we regulate broadcasting, which is defined as broadcasting across the country, with those objectives in mind.
