Canadian Prime Minister Mark Carney said Thursday that trade negotiations with the United States have turned "nasty," a sharp assessment that came after President Donald Trump publicly derided Canada and threatened to expand tariffs on Canadian imports.

The talks are operating under a concrete deadline: proposed 50 percent tariffs are scheduled to take effect in two weeks, targeting a broad range of Canadian goods.

Carney said Canada remains at the negotiating table despite Trump's comments, framing the talks as a critical effort to protect Canadian workers and businesses. He called it a "tough negotiation."

Carney's use of "nasty" mirrored Trump's own description of Canadian leadership, giving the dispute a personal edge that runs alongside the economic one.

For Canadian industries dependent on cross-border trade, 50 percent tariffs would mean direct pressure on jobs and margins. Trump has used the tariff threat as leverage to push Canadian negotiators toward U.S. demands.
