Trade talks with Canada ahead of the mandatory review of the continental trade pact are lagging behind those with Mexico, US Trade Representative Jamieson Greer said on Wednesday. …“We’re having talks separately with Canada, but we’ve moved along with Mexico,” Greer said. “Canada is behind on this.” Canada-US Trade Minister Dominic LeBlanc met with Greer 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-US relations. …But no announcement of formal negotiations with Canada has emerged from the Trump administration since that meeting took place. …Greer has complained that Canadians maintain barriers that make it difficult to hold bilateral trade talks, citing provincial bans on US alcohol. …Greer also has floated the idea of abandoning the trade pact in favour of two separate bilateral agreements with America’s closest neighbours.
