I never took a stance on it.
Examples of federal Crown corporations include:
the Canadian Broadcasting Corporation
Canada Post
These are fine, fairly high quality in terms of service. And I guess in general these two having revenue streams and self funding mean that I don't pay taxes to run a national broadcaster and our postal service.
I would rather not have junk mail or advertisements in our public broadcasts. I would have to look at numbers to say whether the taxes are a worthwhile trade-off.
I do not want news or mail to only have corporate owned options, because then capitalist interests would have a much heavier influence on communications is Canada. I wish we had a national crown ISP, for the same reason.
In Canada, state-owned corporations are referred to as Crown corporations, indicating that an organization is established by law, owned by the sovereign (either in right of Canada or a province), and overseen by parliament and cabinet.
