President Donald Trump signed the implementing legislation for the U.S.-Mexico-Canada Agreement (USMCA) Wednesday at a White House ceremony.
The remaining step in the ratification process is now with Canada's parliament, which is expected to approve the deal though timing remains uncertain.
Once ratification is complete, then the three countries have to embark on the process of making sure that regulations/laws reflect provisions of the updated agreement.
After that process is completed, the countries are to notify each other via letters, which will start the implementation process.
