OTTAWA — Canada’s retaliatory tariffs will target Republican states and Donald Trump allies. “Canadians understand that we need to respond to this,” Prime Minister Justin Trudeau said Saturday night. “We need to respond in a way that is appropriate, that is measured but forceful, that meets the moment.”

Tariff retaliation: Mexico and Canada immediately vowed to impose tariffs of their own. The Canadian prime minister, Justin Trudeau, announced retaliatory tariffs starting with 25 percent tariffs on approximately $20 billion worth of U.S. goods on Tuesday, with $85 billion more to follow within three weeks.
