All media are under some influence and has an agenda. "factual" information is another way to say that the narrative is controlled in accordance with societal values.

I think the take away is that Canada is loosing the ability to keep macro beliefs in check.

I'm not sure what you're trying to say here. You are essentially saying that if you decrease the amount you read but increase the quality of what you are reading, the quality of what you are reading will likely go up. That is bordering on a tautology. In the situation you describe you happen to be able to consume less news but increase the quality. That is not the same as the increase in quality being a result of a decrease in news. You seem to be confusing correlation and causation.
