If the United States imposes tariffs on imports of Canadian steel and aluminum, some Americans will lose their jobs and U.S. growth will suffer, Prime Minister Justin Trudeau said on Wednesday.

With U.S. tariffs on all steel and aluminium imports set to come into effect next month, local businesses in Ottawa are bracing for the impact.

The measures announced by Trump are part of his aggressive push to reset global trade in the belief that tax hikes on foreign-made products will strengthen domestic manufacturing.
