WASHINGTON/TORONTO (Reuters) – Contentious U.S.-Canada trade talks ended on Friday with no deal to revamp the North American Free Trade Agreement after the mood soured, and President Donald Trump notified Congress of his intent to sign a bilateral trade pact with Mexico. After four intensive days of talks in Washington between Canada and the United States, the biggest sticking points were familiar ones: U.S. demands for more access to Canada’s closed dairy market and Canadian insistence that a trade dispute settlement system be maintained, not scrapped as Washington wants. “For Canada, the focus is on getting a good deal, and once we have a good deal for Canada, we’ll be done,” the country’s foreign minister, Chrystia Freeland, told a news conference.
