Canada took a first step toward ratifying a new North American trade agreement on Monday just three days ahead of U.S. Vice President Mike Pence's trip to Ottawa to discuss passage of the treaty.

Foreign Minister Chrystia Freeland presented what is known as a "ways and means motion" to the House of Commons, which opens the way for the formal presentation of a bill.

The deal known as the USMCA, which would replace the 25-year-old North American Free Trade Agreement, has yet to be approved by legislatures of the three participating countries — Canada, Mexico and the United States.
