There are calls for Canada to harmonize wheat trade regulations with the United States.

The Western Canadian Wheat Growers Association is concerned about language in the Canada Grain Act that goes back decades.

Executive director Robin Speer says it calls for the automatic downgrading of American wheat imports to the lowest quality.

He is concerned it could potentially open the door to U.S. trade action as the Trump administration looks to renegotiate the North America Free Trade Agreement.
