Early postwar developments
Domestic affairs
King retired as prime minister and leader of the Liberal Party in 1948, and the mantle of leadership passed to Louis Stephen Saint Laurent, a Quebec lawyer whom King had brought into the government in 1941. Saint Laurent continued most of the domestic policies of his predecessor but pursued a more activist foreign policy. His time in office coincided with the intensification of the Cold War in the late 1940s, precipitating higher defense spending. The increased defense expenditures, combined with opposition from provincial governments, eventually forced the Liberal government to curtail plans to expand existing social programs or to introduce such new ones as national health insurance. Saint Laurent was a popular leader, especially in Quebec, and was aided by a strong cabinet team and an effective civil service. He won major victories in the 1949 and 1953 federal elections, reinforcing the notion that the Liberals were destined to govern Canada forever.
Postwar prosperity
After the war, close to a million veterans reentered civilian life, marrying, having children (this was the start of the “baby boom” in Canada), and going on a buying binge. For the first time since the Great Depression years, Canadians indulged themselves, but the dramatic increase in consumption put tremendous pressure on Canada’s balance of payments with the United States: much of what Canadians were buying was manufactured by its southern neighbour. It also added to inflationary pressures that stimulated industrial unrest, especially in 1945–46. Organized labour had virtually doubled in size during the war, and the unions were ready and willing to demonstrate their new strength by staging major auto, steel, and transportation strikes.
In the two decades after 1950, however, Canada enjoyed unprecedented growth and prosperity. Many urban dwellers abandoned the cities in favour of the new suburbs that appeared in the 1950s. The growth of the suburbs stimulated transportation construction, including new freeways and rapid transit systems. Canada’s primary economic activities thrived, but the country also embarked on a new phase of industrial development, spurred by large-scale electronic, aeronautic, nuclear, and chemical engineering. Much of the growth derived from the expansion of earlier established industry, such as steel production, though new sources of minerals were part of the boom of the 1950s. Labrador iron and newly discovered deposits of radium, petroleum, and natural gas gave Canada resources it theretofore had only in comparatively small supply. Mining investment revealed two important phenomena underlying the postwar economy: first, the extent to which Canadian economic growth was financed by American capital, largely in the form of direct investment and American ownership of factories, and, second, the fact that foreign investment, again largely American, aided by the American demand for Canadian materials, made the Canadian boom possible. Investment from abroad was eagerly sought, especially by the provincial governments, and Canada prospered both because of it and because of the resulting advanced technology and management.
Canadians were divided on the merits of U.S. investment. Many agreed with Saint Laurent’s minister of trade and commerce, Clarence Decatur Howe, who argued that increased U.S. investment was beneficial for Canada. But others were uneasy over the growth of U.S. control over Canadian businesses and over the obvious partnership between Howe and American enterprises. Never was this unease more apparent than in May 1956, when Howe tried to ram a bill through the House of Commons that would finance a trans-Canada natural gas pipeline backed primarily by U.S. capital. The opposition created an uproar that politically weakened Howe and the Saint Laurent government.
Ethnic minorities
Much of the new economic development took place in Canada’s northlands and had some part in ending the nomadic hunting life of the forest peoples and the Inuit of the Arctic shores and islands. This contact between the Canadian government and the First Nations (as Canada’s Indians were now commonly called) signaled a new dilemma that Canada faced in trying to deal equitably with its aboriginal peoples. After 1945 it was apparent that the old system for administering First Nations affairs was collapsing, as poverty and disease were rampant on many reserves. Subsequently, health care on the reserves was greatly improved, and in 1959 the Indian Act was amended to increase opportunities for First Nations peoples’ influence on decisions affecting them. The Métis, equal to people of European ancestry according to the law though in fact often treated as purely Indigenous, played an important part in the growing protest. The federal government reacted by granting the franchise for national elections to all Indigenous people in 1960, and several provinces followed suit.
Large-scale immigration challenged Canada’s social structure and contributed to the country’s prodigious economic growth in the decade following the war. In 1948 the government decided to stimulate immigration to Canada, especially from the refugee camps of central Europe, in order to expand Canada’s labour base. The government believed that it was necessary to expand the population if Canada’s industrial growth was to be sustained and a sufficient tax base created to pay for the social welfare measures that had been initiated at the end of the war. More than 125,000 immigrants were admitted in 1948, and, although the flow of arrivals dropped in 1949–50, it subsequently increased to reach a peak of some 282,000 in 1957. The wave of immigration, combined with the higher postwar birth rate, dramatically increased Canada’s population from some 12 million in 1945 to nearly 16 million by the mid-1950s.
As many of the immigrants were from southern Europe, particularly Italy, Greece, and Portugal, immigration added to the numbers of Canadians who were neither French nor British in origin. The changing population mix had profound effects on Canada’s political culture. With the proportion of Canadians of British descent declining, Canada’s ties to Britain, the monarchy, and the Commonwealth weakened, and large numbers of “new” Canadians, as they were called, became active in Canada’s political, economic, and social life. Despite the increasing numbers of immigrants, however, Canadian industry, banks, and large retail establishments continued to be dominated by a small group of largely Protestant, English-speaking families with British roots.
Internal politics
After 21 uninterrupted years in power, a malaise began to settle into the Liberal government. Saint Laurent, though still personally popular, appeared to be old and tired, and it was widely believed that he was losing his grip on the reins of government. Howe’s actions during the debate over the pipeline, many felt, were an indication that he and other Liberal leaders had come to believe in their divine right to govern, and voters were ready to give the Progressive Conservative Party (as the Conservative Party was known after 1942) a chance to lead Canada.
John George Diefenbaker, a new and dynamic Progressive Conservative leader, emerged to end the decades of Liberal rule. A powerful orator, Diefenbaker challenged Canadians to open up the North, diversify their international trade, and end “corrupt” Liberal rule. In 1957 he was elected with a minority government, and the following year he won the largest parliamentary majority in Canadian history up to that time. During Diefenbaker’s term of office, however, Canada suffered a major economic recession. He had to face the strains of an unsuccessful British attempt to enter the European Economic Community (EEC; now commonly known as the European Union); of difficult relations with the United States during its Cuban missile crisis, in which Canada was not consulted and yet was expected to take part in the air defense of North America; and of a domestic struggle over whether or not to install nuclear warheads in Canada and allow their use by the Canadian contingent of the North Atlantic Treaty Organization (NATO). Internal dissension reduced the Diefenbaker government to a minority in the House of Commons in 1962 and to defeat in 1963.
The new Liberal government that followed was led by Lester B. Pearson, who included talented figures in his cabinet, though many of them were inexperienced. He set out to launch “one hundred days of decision,” but he was stopped short when his finance minister, Walter Gordon, backed down from controversial proposals to reduce U.S. investment in Canada. This and other blunders and scandals dogged Pearson during his entire five years in office. Pearson never achieved a majority government—though he sought one in federal elections in 1965—but his government was one of the most productive in Canadian history. Under Pearson, Canada gained a national flag, a national social security system (the Canada Pension Plan), and a national health insurance program, and federal public servants won the right to free collective bargaining. While accomplishing all this, however, Pearson was also hampered by the rise of nationalism and separatism in Quebec, and he announced his retirement in late 1967.
