Canada’s steel industry fears that Chinese steel facing steep tariffs in the United States will be sent north and overwhelm the Canadian market.

Revenue from customs import duties rose to $2.4 billion in April and May, according to data released Friday by Canada’s Department of Finance. That’s up from $842 million in the same period a year earlier, capturing revenue from retaliatory tariffs that Prime Minister Mark Carney has levied on imports of some US goods.

Prime Minister Mark Carney on Wednesday said Canada will introduce a tariff rate quota for countries with which it has free trade agreements, excluding the United States, to protect the domestic steel industry.

Cleveland-Cliffs Inc.’s chief executive Lourenco Goncalves is calling on Prime Minister Mark Carney to implement punishing steel import tariffs to protect the nation’s industry.

Canada will reduce the amount of foreign steel that importers can bring in tariff-free, a move to help domestic producers suffering from US President Donald Trump’s levies on the sector.

President Donald Trump’s tariffs could have an unintended side effect: making homeownership even less affordable for many Americans.

Manufacturing in Canada has been jolted by the abrupt swing in America's approach to trade and the frequently changing tariffs President Trump has imposed on imports into the U.S. In June, Trump called for a doubling of so-called Section 232 tariffs on steel and aluminum to 50%.

April 9: Trump's higher "reciprocal tariffs" begin just after midnight. Hours later, the president says he is issuing a 90-day pause on those duties, except for China. Trump raises tariffs on Chinese goods from 104% to 145%, the highest rate so far this year.
