Canadian ministers emerged from a lengthy, high-level meeting between Canada and the United States on Thursday without immediate relief from U.S. tariffs on Canadian imports, but they said the discussion was constructive and that talks would continue.

Canada on Wednesday announced new retaliatory trade duties on some $21 billion worth of U.S. goods, a response to Trump implementing universal steel and aluminum tariffs. Canada's former Deputy PM Chrystia Freeland joins Morning Joe to discuss.

President Donald Trump on Tuesday backed off a 50% tariff on imports of Canadian steel and aluminum, ratcheting down a threat against a major U.S. trading partner on another day of whiplash for U.S. stocks.
