"where institutions can sign up to using a federal DNS service provided through the domain registrar..."
The domain registrar is CIRA, and has only one of twelve board members having a federal government affiliation. See cira.ca for the facts. Their Canadian Shield services uses data from Akamai, Mozilla, and CCCS.
It is not "federal".
Sigh. Another comment from someone's memory that takes only 2 minutes to fact-check and discover to be incorrect.
