Canadian tariffs on $12.6 billion worth of US goods begin Sunday as a response to President Trump's trade policies.

US Steel and iron will have a 25% tariff, matching the amount the US placed on imported steel.

Prime Minister Trudeau spoke about the new tariffs in Canada's tomato capital, a city that had a Heinz plant for over 100 years until 2014.

OTTAWA, Ontario (AP) — Canada began imposing tariffs Sunday on $12.6 billion in US goods as retaliation for the Trump administration's new taxes on steel and aluminum imported to the United States.

Some US products, mostly steel and iron, face 25% tariffs, the same penalty the United States slapped on imported steel at the end of May. Other US imports, from ketchup to pizza to dishwasher detergent, will face a 10% tariff at the Canadian border, the same as America's tax on imported aluminum.

Trump had enraged Canada and other US allies by declaring imported steel and aluminum a threat to America's national security and therefore a legitimate target for US tariffs. Canada is the United States' second-biggest trading partner in goods, just behind China.

Speaking Sunday in Leamington, Ontario, Prime Minister Justin Trudeau thanked Canadians for standing united against President Donald Trump's sanctions. He urged Canadians to "make their choices accordingly" in considering whether to buy American products.

The selection of Leamington, known as Canada's tomato capital, was no accident. The town is home to a food-processing plant that supplies tomato paste and other products to French's, a major competitor of Kraft Heinz. Heinz left Canada and sold its Leamington plant in 2014, after 105 years of Canadian operations.

The new Canadian tariffs, which took effect at 12:01 a.m. Sunday, are hitting a long list of US consumer goods, including ketchup and other Kraft Heinz products.

As part of his combative America First approach, Trump has repeatedly attacked the trade policies of the United States' northern neighbor, citing Canada's triple-digit tariffs on dairy products, which account for only about 0.1% of US-Canada trade. The United States, in fact, last year enjoyed a $2.8 billion overall trade surplus with Canada.

Trump has also tried to pressure Canada and Mexico into agreeing to rewrite the 24-year-old North American Free Trade Agreement to shift more auto production and investment to the United States.

But that effort has stalled, and Trump said Sunday that he didn't expect a deal that he could support until after the US midterm elections in November.
