Is the U.S. dumping grain in Canada? Canada thinks so

From The Vancuver Sun - Canada to impose duties on U.S. corn imports

OTTAWA -- Canada said Thursday it is imposing provisional duties on U.S. grain corn after a preliminary finding by the Canada Border Services Agency that imports of unprocessed grain corn from the United States are being dumped and subsidized. The decision came two months after the agency began investigating complaints from Canadian farmers that Washington was dumping and subsidizing grain corn.
