President Trump doubled tariffs on Canadian steel and aluminum imports to 50%, sparking outrage and warnings of "catastrophic" job losses in Canada. This move, despite recent attempts to mend relations, threatens Canada's steel industry, a C$15 billion sector employing 23,000. Canada's Prime Minister Carney reaffirmed Canada's sovereignty amidst Trump's annexation suggestions and retaliatory tariffs. The new tariffs, effective Wednesday, could significantly disrupt supply chains and severely impact both Canadian and US economies. Canada is planning retaliatory measures.
