After trade talks between Canada and the United States broke down Friday, Prime Minister Mark Carney said the Americans had made unfair, last-minute changes to the proposed terms. On the weekend, a list began circulating online that claimed to summarize the key U.S. demands affecting areas including supply management, infrastructure projects and critical minerals. The list provided no sourcing. While some of the items on it have been identified by Canada as sticking points, there is no evidence that Canadian or American officials have released such a comprehensive list.
