The Canadian steel industry had asked the government to introduce tougher anti-dumping measures to protect the domestic industry. U.S. President Donald Trump increased import duties on steel and aluminum to 50% from 25% earlier this month. Canada is the top seller of steel to the United States.

OTTAWA — Canada is moving to shore up its domestic steel industry amid U.S. President Donald Trump's ongoing global trade war, with new tariffs targeting China and other countries around the world.

Trump threatened to escalate tariffs beyond 35% if Canada opts to retaliate with tariffs on U.S. goods. Canadian goods are also subject to sector-specific tariffs, such as 50% levies on steel and aluminum as well as 25% tariffs on non-USMCA compliant autos and auto parts.
