How much of Canadian merchandise trade was conducted under NAFTA by 2008?

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 trade volume the test wants is therefore over $1 trillion.

Three numbers anchor NAFTA. Discover Canada commits NAFTA to THREE specific quantitative facts: over 444 million people across the three countries, over $1 trillion in merchandise trade, and 2008 as the year of measurement. So NAFTA's economic scale is documented at trillion-dollar level by 2008 — making it one of the largest trade zones in the world.

NAFTA evolved in two stages. Discover Canada commits NAFTA's timeline to TWO milestones: 1988 Canada enacted free trade with the United States, and 1994 Mexico became a partner in the broader NAFTA. So the trillion-dollar figure represents trade across all three NAFTA partners — Canada, the United States, and Mexico — fourteen years after Mexico's entry, in 2008.

The trade volume reflects integrated supply chains. Discover Canada writes that "as Canadians, we could not maintain our standard of living without engaging in trade with other nations," and that "Canada enjoys close relations with the United States and each is the other's largest trading partner. Over three-quarters of Canadian exports are destined for the U.S.A. In fact we have the biggest bilateral trading relationship in the world. Integrated Canada-U.S.A. supply chains compete with the rest of the world." So the over-$1-trillion NAFTA merchandise trade reflects a deeply integrated three-country economic zone — the bilateral Canada-U.S. relationship is described as the biggest in the world, and Mexico's addition to NAFTA brought millions of additional consumers and producers into the same supply-chain framework. The 2008 figure measures the depth of this economic integration. When the test asks how much merchandise trade was conducted under NAFTA by 2008, the source-precise answer is the trillion-dollar figure: over $1 trillion.

The question is testing whether new citizens know NAFTA's 2008 merchandise trade volume. Discover Canada commits to one figure: over $1 trillion. The right test answer matches that.

The wrong answer choices each pick a different scale. "Over $500 billion" is half a trillion — too low. "Over $750 billion" is also too low. "Over $2 trillion" is too high — the source commits to over-$1-trillion, not over-$2. Only the over-$1-trillion answer matches.
