Study Tip
Canada's largest trading partner is a country that shares a long border with Canada. This country is also one of Canada's closest cultural and economic allies.
What should you know about this topic?
The United States is Canada's largest trading partner by far. Discover Canada notes that Canada enjoys close relations with the United States and that the two countries share the world's longest undefended international border. A very large share of Canadian exports, including energy, cars and car parts, forest products and food, goes to American buyers.
Trade between the two countries has been shaped by agreements. In 1988 Canada signed a Free Trade Agreement with the United States. In 1994 the North American Free Trade Agreement (NAFTA) added Mexico, creating one of the largest free trade areas in the world. NAFTA was later replaced by the Canada-United States-Mexico Agreement (CUSMA), which took effect in 2020.
Canada is a trading nation; trade has been key to its prosperity since the days of the fur trade. Canada also trades with many other countries, including China, Mexico, Japan and members of the European Union, and it belongs to the G7 group of leading industrialized economies. However, the United States remains the most important market because of geography, shared infrastructure and deep economic ties. For the test, connect this question with Canada's economy, its three main industry types (service, manufacturing and natural resources) and its international relations.
Why are the other answers wrong?
- China: China is a major trading partner, but Canada trades far more with the United States.
- Japan: Japan is an important Asian trading partner, but well behind the United States.
- Mexico: Mexico is a free trade partner through NAFTA and CUSMA, but its trade with Canada is much smaller than U.S. trade.
What is the most common mistake?
China and Mexico are important partners, so they can seem tempting. Remember the closest neighbour is also the biggest customer: the United States.
How can you remember the answer?
"Next door, most trade": the neighbour you share the longest border with is the one you trade with most.
