US-Canada trade talks just fell apart. 50% tariffs now hitting billions in Canadian goods.

What happened:

Canada's PM Carney says he'll match tariffs dollar-for-dollar. We're talking ~$20B worth of stuff—plywood, liquor, electrical equipment, hockey gear, you name it.

US Trade Rep claims Canada "upset the balance" after days of negotiating. They were close to a deal: 25% on steel/aluminum, 15% on autos. Now? Dead.

This isn't just noise. US-Canada trade is massive. Any sustained tariff war hits supply chains, raises costs for consumers, and creates uncertainty for companies on both sides of the border.

Markets hate uncertainty. Watch how this plays into inflation expectations, Fed policy assumptions, and cross-border equities. If this escalates, it's not just a headline—it's a real drag on growth.
