CUSMA Canada: What Canadian Businesses Need to Know About the Canada-United States-Mexico Agreement (2026 Guide)
The Canada-United States-Mexico Agreement (CUSMA) is Canada’s most important trade agreement. It governs trade between Canada, the United States, and Mexico — three countries representing one of the largest free trade regions in the world.
For Canadian businesses, CUSMA provides preferential access to markets representing over 500 million consumers and trillions in economic activity.
Understanding how CUSMA works is essential for any Canadian company that exports or plans to export to the United States or Mexico.
What Is CUSMA?
CUSMA (Canada-United States-Mexico Agreement) is a free trade agreement between:
🇨🇦 Canada
🇺🇸 United States

It came into effect on July 1, 2020, replacing the North American Free Trade Agreement (NAFTA).
CUSMA modernized the original agreement to reflect today’s economy, including digital trade, intellectual property, and updated rules of origin.
