Trade policy has played a larger role in the internal and international relations of Canada than of the United States, certainly in the last half century. There are many reasons for this: The Canadian economy is more open than that of the United States (e.g., merchandise exports as a percentage of gross national product were 30% in Canada and 7% in the United States in 1982); the United States is far more dominant in Canada's trade than any single country or group of countries such as the European Economic Community is in U.S. trade (in recent years about 70% of Canada's exports have been sent to the United States and more than 70% of its imports came from the United States; for the United States, about 15% of its exports in recent years went to Canada, its major trading partner, and between 15% and 20% of its imports have come from Canada); and with this double dependence on trade and on a single market, a selfinterested foreign policy must concentrate on trade policy (Grey, 1981: 3-4).
