WASHINGTON — United States Trade Representative Jamieson Greer says talks with Canada ahead of the mandatory review of the continental trade pact are lagging behind those with Mexico.

Speaking on Fox Business today, Greer says talks are moving ahead with his Mexican counterparts as the Trump administration negotiates changes to the Canada-U.S.-Mexico Agreement on trade, better known as CUSMA.

Canada-U.S. Trade Minister Dominic LeBlanc met with Greer in Washington on March 6, days after the Trump administration announced it was officially beginning negotiations with Mexico.

The meeting was seen by some as a sign of a thaw in Canada-U.S. relations after President Donald Trump froze negotiations with Canada last year because he was angered by an Ontario-sponsored ad quoting former president Ronald Reagan criticizing tariffs.

But no announcement of formal negotiations with Canada has emerged from the Trump administration since the meeting took place.

CUSMA, which was negotiated during the first Trump administration, has shielded Canada and Mexico from the worst impacts of Trump’s tariffs.
