I could look at the August 2, 1993,
the agreement between Ogilvy Renault and Mr. Mulroney,
and it speaks very clearly of
“[...] compensation and other forms of earnings shall remain yours alone [...]”
That means “unique to Mr. Mulroney”.
But it doesn't talk about his consulting firm that he mentions existed, and you know of no name of a consulting firm like “Brion” or “Devon” or “Mulroney Investments” or whatever? You know of no firm like that?
