President Trump signed the implementing legislation for the USMCA yesterday, making the United States the second of the three countries, after Mexico last December, to sign the agreement.  The USMCA will not take effect until 90 days after it is ratified by Canada. The Liberals currently operate a minority government, and while the Conservatives have stated that they ultimately aim to move USMCA forward, other opposition parties have either opposed the USMCA or expressed that negotiations could be quite lengthy.  To read a brief overview of the main changes USMCA makes to NAFTA, please see our previous post on the issue.
