The North American Free Trade Agreement (NAFTA), effective January 1, 1994, created a trilateral trade bloc among Canada, Mexico, and the United States, aimed at reducing trade barriers and protecting intellectual property. It addressed tariffs on goods, labor rights, and environmental standards, providing benefits such as duty-free access and increased competitiveness for businesses. While NAFTA spurred trade and investment, it also led to job losses in manufacturing and increased trade deficits in the U.S.
