Chicago: After trade negotiations crumbled at the eleventh hour, U.S. President Donald Trump's 50% tariffs on scores of Canadian imports kicked in Saturday.
The new levies are expected to affect about 5% of Canada's annual exports to the U.S., roughly $20 billion in goods ranging from hockey sticks to agricultural products. Canada's Prime Minister Mark Carney quickly promised Saturday that his government would roll out "dollar for dollar" retaliatory measures starting Sept. 8.
