International Trade Minister Stockwell Day is none too pleased that a controversial “Buy American” provision in the U.S. economic stimulus package hasn’t yet been removed. Under rules released this month, state and local governments must spend the money on goods from a list of countries that excludes Canada. Day told the U.S. Chamber of Commerce in Washington yesterday that the move sends “a very unfortunate message” and warned that Canada might retaliate. “One thing leads to another,” Day said. U.S. officials have for their part defended the provision, saying it is entirely consistent with their country’s international trade obligations.
