Canada supplies roughly 60% to 70% of the imports that come into the U.S. market. Canadian suppliers like Rio Tinto produce high quality aluminum that is typically sold to stateside buyers.

U.S. tariffs could cause the prices of steel and aluminum cans to rise, an increase that may ultimately be passed on to consumers.

The new 25% tariff rates on steel and aluminum imports into the United States are due to take effect on March 12, according to the executive orders signed by President Donald Trump on Monday.
