Again, the requirement is simply that the regulations prescribe a body for the purposes of designating organizations for the definition. It does not touch on what that body might be, but the term “body” is used throughout the Income Tax Act to refer to a variety of not even just entities but things from administrative tribunals to new government agencies.
That is a fairly broad term, and I don't want to imply that this legislation requires or establishes a separate administrative tribunal, for example, when it doesn't. It just has the requirement that a body be prescribed for the purposes of the “qualified Canadian journalism organization” definition.
