What does the north american free trade agreement (nafta) do for canada, mexico, and the united states

The North American Free Trade Agreement (NAFTA) is a free trade agreement between Canada, Mexico and the United States. It entered into force on 1 January 1994. The agreement is the most far-reaching trade liberalization agreement in the world with the European Union's internal market.  

The United States-Mexico-Canada Agreement (USMCA) has been negotiated to replace the Free Trade Agreement.

Since its inception, NAFTA has removed tariff and non-tariff barriers to trade and investment between Canada, the United States and Mexico. This has achieved a strong and credible investment framework. In addition, NAFTA has helped to create a reliable and stable environment for long-term investment. In addition, levels of trade and investment in North America have risen, leading to strong growth, job creation and better prices and choice for consumer goods. This has benefited companies in all three countries, paving the way for low taxes, new partnerships and new opportunities.
