Canada’s prime minister and Mexico’s president ordered retaliatory tariffs on goods from the U.S, following through with their threats after U.S. Donald Trump sparked a trade war by imposing sweeping tariffs on imports from Canada,

Canada hopes hefty tariffs imposed by U.S. President Donald Trump will not take effect on Tuesday but the Canadian public expects the government to stand firm in a trade dispute with Washington, the Canadian ambassador told ABC News on Sunday.

President Donald Trump signed an executive order Saturday imposing a 25% tariff on imports from Mexico and Canada and 10% on imported Chinese goods, according to multiple reports, reflecting his campaign promises to implement high tariffs, against the views of many economists who believe Trump’s plan would burden everyday consumers.
