The Globe and Mail reports in its Monday, March 31, edition that it is tariff week in the United States, marking a critical moment in President Donald Trump's efforts to reshape global trade. The Globe's triple-bylined item, led by Nathan VanderKlippe, says that on April 2, the White House plans to unveil a series of reciprocal tariffs, though the specifics remain uncertain. Canada faces significant risks as new trade levies coincide with a proposed 25-per-cent tax on non-U.S. made cars and auto parts, alongside an expiration of a reprieve on tariffs under the U.S.-Mexico-Canada Agreement. Flavio Volpe, president of Canada's Automotive Parts Manufacturers Association, noted that this could lead to four layers of tariffs, signalling a potential shift away from continental free trade under a U.S. president who disregards previous agreements. Prime Minister Mark Carney has announced retaliatory tariffs in response to any U.S. levies targeting Canada, following a call with President Trump. As he campaigns for the Liberal leadership in the April 28 federal election, Mr. Carney mentioned that the government is prepared with another round of potential tariffs on up to $125-billion worth of American goods.
