I've had enough correspondence with the Standing Joint Committee for the Scrutiny of Regulations to know better than to provide a definitive answer to Mr. Perkins as to whether or not the regulation-making authority in proposed paragraph 122(1)(e) would compose sufficient room to issue regulations on the basis of the preamble, but I'll say likely not. Normally, a statute needs to indicate that regulations are to be prescribed, or it can use terms like “prescribed entity” and then draw on the power of paragraph (e) to say what those prescribed entities actually are.
As I said, I am not going to be definitive, but all of that is to say that if this term ends up in the preamble, as I've noted, it's the likely space from which OPC guidance would probably be forthcoming.
