President Donald Trump’s additional 50% tariff on a slew of Canadian goods is likely to complicate the administration’s talks on Tuesday in Mexico on the US-Mexico-Canada free trade agreement, which Trump has indicated he wants to exit. The tariffs, which officials characterized as a response to Canada’s “discriminatory” practices, affect goods ranging from wine to hockey sticks and will formally take effect in 30 days. “I’m not a fan of tariffs. Canada, I worry they’re not engaging,” said Rep. Adrian Smith, R-Neb. And the move could be subject to legal challenges: Trump signed the tariffs pursuant to Section 338 of the Tariff Act.
