ABSTRACT
Trade in energy resources has been one of the major links in the US-Canadian relationship in the post-World War II period. Canada has been an important source of both oil and natural gas for the United States, and the United States has, in turn, supplied a large share of Canada's domestic coal requirements. The importance of mineral fuels in overall trade between the United States and Canada has grown considerably. In 1956, exports of mineral fuels represented only 2.6 percent of total Canadian exports and only 4.3 percent of total Canadian exports to the United States. Oil is the energy resource that has figured most prominently in the US Canadian context. During the 1950s and 1960s the focus of oil policy in both the United States and Canada was on expanding domestic production. US oil policy, meanwhile, was concerned about expanding domestic oil production for national security reasons.
