Canada is looking at ways to boost the effectiveness of its retaliatory tariffs against the United States, Foreign Minister Chrystia Freeland said on Tuesday

David MacNaughton says he's hearing complaints from some Americans about the pain caused by Ottawa's retaliation against the Trump administration's steel and aluminum tariffs.

Prime Minister Justin Trudeau confronted U.S. President Donald Trump over his steel tariffs at the signing of the new USMCA trade deal on Friday.

Here are the states most impacted by Canada's retaliatory tariffs, and how they voted.

Less than half of Americans expect Donald Trump’s tariffs to do much to help the U.S. economy, but their widespread unpopularity hasn’t led most Republicans to stray from supporting the president’s trade policy.

Navdeep Bains said Plan A is to continue encouraging the U.S. to back away from the tariff threat, which industry has warned would inflict significant damage on both countries' economies.

Canadians heading to the grocery store may have to pay more at the checkout counter due to the ongoing tariff spat between Canada and the U.S.

"Canada must wait. Their Tariffs and Trade Barriers are far too high. Will tax cars if we can’t make a deal!" the president's tweet read.

Trump has threatened to impose tariffs under Section 232 of the decades-old U.S. Trade Expansion Act.

Canada, the E.U. Japan, Mexico and South Korea will meet next week to discuss how to respond to threats by Trump to impose tariffs on U.S. imports of autos and car parts, officials familiar with the talks said.
