Freeland leaves D.C. with no tariff deal, despite early optimism from U.S.

Foreign Affairs Minister Chrystia Freeland came and went from Washington, shifting diplomatic gears and jetting to Havana on a day that saw early hope that the end of the Canada-US tariff dispute was close.

However, that hope fizzled in a puff of figurative smoke.

Freeland had no new developments to report as she emerged in the morning from the headquarters of the United States Trade Representative.

During testimony before a US Senate subcommittee, Treasury Secretary Steven Mnuchin said an understanding with Mexico and Canada was close.

Mnuchin replying to a question as to why Canada and Mexico continue to face a 25 per cent duty on steel and 10 per cent levy on aluminum exports to the US.

Freeland expressed optimism over incremental progress, though she refused to speculate publicly on whether a resolution of Canada's trade dispute with the US is close at hand.
