Mexico’s restrictions on products made with genetically modified corn, has lead to Canada joining the United States in a trade dispute. 

Trade Minister Mary Ng and Agriculture Minister Lawrence MacAulay say Canada will take part in dispute resolution proceedings as a third party. 

Mexico imposed a ban in February on importing tortillas or dough made with biotech corn — a move its trading partners say is contrary to the U.S.-Mexico-Canada Agreement. 

A dispute settlement panel under the terms of the deal, known in Canada as CUSMA, was announced last week by U.S. Trade Representative Katherine Tai. 

Tai and U.S. Agriculture Secretary Tom Vilsack say the ban is not based on science and ignores clear evidence that genetically modified corn is safe.
