I expect that Joly is going 'by the book', doing everything according to the legal procedure, so that if the American billionaire MAGA shithead defies the order to follow the agreement that he had signed when he purchased Stelco, the Canadian government will be legally covered for their (I hope full-strength) response.
We need to demonstrate to American billionaires that agreements should not be signed in pencil, that a signature on an agreement means that there will be severe consequences to breaking said agreements.
