Canada Retaliates With Dollar-for-Dollar Tariffs in Trade War.

The U.S. imposed 50% tariffs on a large slice of Canadian imports early Saturday after three days of talks in Washington failed to produce a deal. Canadian Prime Minister Mark Carney suspended negotiations and promised to retaliate in kind.

• 50% tariffs cover roughly $20–28 billion worth of Canadian goods.
• Affected products include dairy, electronics, industrial machinery, and autos.
• $880 billion in goods and services crossed the border between the two countries last year.
• Trump had extended the original Wednesday deadline by three days to allow more time.

Why it matters: The tariffs hit about 5% of all Canadian exports to the U.S. annually, adding to existing levies on steel, lumber, and autos. Julian Karaguesian, a trade expert at McGill University, said 50% tariffs would effectively push hundreds of Canadian goods out of the U.S. market.

• Canada's retaliatory tariffs would raise costs on U.S. goods flowing north, putting pressure on businesses on both sides of the border.
