When did Mexico become a partner in NAFTA?

Discover Canada records this in one direct sentence. The guide writes: In 1988, Canada enacted free trade with the United States. Mexico became a partner in 1994 in the broader North American Free Trade Agreement (NAFTA), with over 444 million people and over $1 trillion in merchandise trade in 2008. The year the test wants is therefore 1994.

Two dates anchor the trade story. Discover Canada commits to 1988 for the original Canada-U.S. free trade agreement, and 1994 for Mexico becoming a partner in the broader NAFTA. So 1994 is the trilateral expansion: from a two-country pact (Canada and the U.S.) to a three-country North American agreement.

NAFTA's scale dwarfs typical bilateral trade. Discover Canada commits to "over 444 million people" in the NAFTA zone — making it one of the world's largest free-trade areas — and "over $1 trillion in merchandise trade in 2008." So the 1994 expansion brought a third major economy into a region that, by 2008, was moving more than a trillion dollars in goods between its three members each year.

Free trade fits Canada's identity as a trading nation. Discover Canada writes that "Canada has always been a trading nation and commerce remains the engine of economic growth." Today Canada has "one of the ten largest economies in the world" and is in the G8 with the United States, Germany, the United Kingdom, Italy, France, Japan and Russia. The 1994 NAFTA partnership with Mexico expanded Canada's free-trade footprint, integrated supply chains across three countries, and continues to shape Canadian commerce.

The 1994 expansion also matters because it links Canada into a larger North American framework. Discover Canada describes Canada as having close trade ties with the United States — "the biggest bilateral trading relationship in the world" — and the 1994 NAFTA expansion broadened that relationship to include Mexico, creating a single legal framework for the three-country trade flow. So 1994 is not just a date — it is the year North American free trade became continental.

The question is testing whether new citizens know when Mexico joined NAFTA. Discover Canada commits to one year: 1994. The right test answer matches that.

The wrong answer choices each pick a different year. 1988 is the year Canada first enacted free trade with the United States — bilaterally, before Mexico joined. other years in the option list are not named in the guide as NAFTA-related milestones. Only 1994 — the year Mexico joined — matches.
