The Postwar Boom: Baby Boom, Suburbs, Economy and Technology

Why Canada boomed after 1945 instead of sliding back into depression, how the baby boom and the suburbs changed family life, which megaprojects and new technologies (the Seaway, the Trans-Canada Highway, television, CANDU reactors, Alouette, the Avro Arrow, the Canadarm) reshaped the country, and why the benefits and costs of growth were shared so unequally, especially for First Nations, Métis and Inuit communities.

Key things to remember

  1. 1The postwar boom (about 1945 to the early 1970s) was driven by wartime savings, pent-up demand, government spending, Cold War demand for resources and American investment.
  2. 2Statistics Canada dates the baby boom from 1946 to 1965; births peaked at about 479,000 in 1959.
  3. 3Newfoundland joined Canada on March 31, 1949; the Trans-Canada Highway opened in 1962 and the St. Lawrence Seaway in 1959.
  4. 4The Rand Formula (1946) required all workers under a union contract to pay dues, strengthening unions.
  5. 5Key technology: CANDU reactors (1962 onward), Alouette 1 (1962), the cancelled Avro Arrow (1959), Anik A1 (1972) and the Canadarm (1981).
  6. 6The 1970s brought oil shocks (1973, 1979) and stagflation, ending with the recession of 1981–1982.

Picture a young couple in 1955. He served overseas in the war; she worked in a munitions plant and then married him. They have three children under eight, a new bungalow on a curving street in a brand-new suburb, a car in the driveway, a television in the living room and a mortgage backed by the federal government. Ten years earlier, many Canadians had feared that peace would bring back the breadlines of the 1930s (see Unit 3). Instead, the quarter-century after 1945 became the longest boom in Canadian history. This lesson asks why it happened, how it changed daily life, and who was left out.

Why the boom happened

Several forces worked together. Canadians had saved money during the war (much of it in Victory Bonds) and now wanted the houses, cars and appliances they had gone without since 1929. Government spending stayed high: veterans' benefits, the Family Allowance cheques that began in 1945, and loans for housing all put money in people's pockets. Around the world, rebuilding Europe and the arms race of the Cold War created huge demand for Canadian wheat, lumber, metals and energy. In February 1947, the Leduc No. 1 well struck oil near Edmonton, launching Alberta's oil boom. Iron ore in northern Quebec and Labrador, uranium near Elliot Lake and nickel at Thompson, Manitoba, drew mines, railways and new towns into the North.

Economic trendWhat happenedWho gained and who paid
Resource boomOil in Alberta (from 1947), iron ore, uranium, nickel, pulp and paper, hydroelectric damsJobs and high wages for many workers; but mines, dams and flooding often took place on First Nations, Métis and Inuit lands without their consent
American investment and branch plantsUS companies built or bought factories and mines in Canada; by the 1970s foreign firms controlled a large share of Canadian manufacturing and oilBrought money and jobs, but profits and key decisions flowed to the United States, raising fears for Canadian economic independence
Unions and the Rand FormulaAfter the 1945 Ford strike in Windsor, Justice Ivan Rand ruled in January 1946 that all workers covered by a union contract must pay union dues, whether or not they joinUnions grew stronger and wages rose; employers had to bargain with stable unions
Consumerism and creditCars, appliances, televisions, shopping malls and instalment buying; bank credit cards spread from the late 1960sHigher living standards for many families, along with more household debt
Crises of the 1970s and early 1980sOil price shocks in 1973 and 1979, stagflation (high inflation plus high unemployment), and a deep recession in 1981–1982Oil-producing Alberta gained while oil-importing regions paid more; interest rates near 20 per cent in 1981 cost some families their homes and farms
Key trends in the Canadian economy, 1945–1982, and their uneven impact.

The baby boom and the suburbs

Statistics Canada dates the baby boom from 1946 to 1965. Births peaked at about 479,000 in 1959, when the average woman was expected to have nearly four children (a total fertility rate of about 3.9). The population also grew through immigration, through tens of thousands of war brides (mostly British and Dutch women who had married Canadian servicemen) and their children, and when Newfoundland joined Canada on March 31, 1949, after a close referendum in which about 52 per cent voted for Confederation. Young families flocked to suburbs built on farmland around the cities. Don Mills, built by E. P. Taylor's company on about 2,000 acres north of Toronto from the early 1950s, became a model for planned suburbs across the country, with curving streets, a shopping plaza and space for a car.

  • Schools: thousands of new elementary schools in the 1950s, then high schools and new universities and colleges in the 1960s as boomers grew up.
  • A youth culture: by the late 1950s teenagers were a market of their own, with rock 'n' roll, radio, dances, cars and fashions that worried many parents.
  • Cars and commuting: suburbs depended on cars, which drove highway building, shopping malls and drive-ins, and left people without cars more isolated.
  • Long-term consequences: the boom generation's size later shaped housing prices, the job market and today's pressures on pensions and health care as boomers retire.
Historical perspective: whose boom?
The image of the prosperous suburban family is real, but it is not the whole story. Many women who had worked in wartime industries were pushed out of paid jobs. Atlantic Canada and many rural areas grew much more slowly than Ontario, Alberta and British Columbia. Some suburban deeds contained restrictive covenants barring Jewish, Black or other buyers until courts and laws began to strike them down around 1950. And on many reserves, in Métis communities and in the North, houses lacked running water while new mines and dams changed the land. Ask whose experience a source describes before treating it as typical.

ProjectDatesSignificance
Trans-Canada HighwayAct passed 1949; officially opened at Rogers Pass on September 3, 1962; finished to the standard set by the Act by 1971Ran through all ten provinces (about 7,800 km, with ferry links to Newfoundland and Prince Edward Island) and boosted trucking and tourism
TelevisionCBC Television began broadcasting in September 1952 in Montreal and TorontoBrought shared programs, news and hockey into homes; also spread American shows and culture
St. Lawrence SeawayBuilt jointly with the United States; opened to ships in April 1959 and officially opened in June 1959Let ocean-going ships reach the Great Lakes and generated hydroelectric power; about 6,500 Ontario residents were relocated and the "Lost Villages" were flooded on July 1, 1958, and the Mohawk community of Kahnawà:ke was cut off from its river shore

Cobalt-60 cancer therapyFirst patients treated in London, Ontario, and Saskatoon in late 1951Canadian machines delivered powerful, precise radiation to tumours and were sold around the world
Cardiac pacemaker researchWilfred Bigelow's team in Toronto, 1950Helped lead to the electronic pacemaker that keeps millions of hearts beating
CANDU nuclear reactorsFirst demonstration reactor at Rolphton, Ontario, 1962; Pickering station from 1971Ontario gained a major source of electricity without burning coal, but created long-lived radioactive waste; uranium mining affected communities near the mines
Avro Arrow (CF-105)First flight March 1958; cancelled February 20, 1959A world-class jet interceptor; its cancellation cost about 14,000 Avro jobs and remains a symbol of lost Canadian ambition (see the Cold War lesson)
Alouette 1Launched September 29, 1962Made Canada the third country, after the Soviet Union and the United States, to design and build its own satellite; it studied the upper atmosphere to improve radio communication in the North
Anik A1Launched November 9, 1972One of the world's first national domestic communications satellites; it brought live CBC television and better telephone service to the North
CanadarmFirst flew on the US space shuttle Columbia in November 1981A Canadian-built robotic arm that became a symbol of Canadian space technology

Assessing significance: technology in the North
New technology reached the Arctic fast after 1945, often for military reasons. The DEW Line radar stations of the 1950s brought wage jobs and supplies to some Inuit communities, but also disrupted hunting life and drew families toward settlements. Thousands of Inuit with tuberculosis were taken south to sanatoria by ship in the 1950s and early 1960s, some for years and some never to return. Satellite television from 1972 connected the North to the South, and Inuit worried it would weaken Inuktut; Inuit organizations pushed for their own programming, and the Inuit Broadcasting Corporation began broadcasting in January 1982. The same technology could mean opportunity and loss.
Continuity and change
When you assess the boom, separate what changed (incomes, suburbs, cars, television, family size) from what stayed the same (Canada's dependence on exporting resources, regional inequality, and limited control over their own lands for many Indigenous communities). Strong answers name both.

Worked examples

Reveal one step at a time and try to beat it to the next line.

Example 1
Use historical statistics: births in Canada rose from fewer than 300,000 a year during the war to a peak of about 479,000 in 1959, then fell sharply after the mid-1960s. Explain what caused the baby boom and one consequence for later decades.
Example 2
Evaluate the claim: "The St. Lawrence Seaway was a success for everyone in Canada."
Example 3
Assess the significance of Alouette 1 (1962) for Canada.

Where marks get lost

  • Writing that the whole country shared equally in the boom. Atlantic Canada, many rural areas, and many First Nations, Métis and Inuit communities saw far fewer benefits, and some bore the costs of dams, mines and relocations.
  • Dating the baby boom to the war years. Statistics Canada dates it 1946–1965, with a peak in 1959.
  • Thinking the Seaway was purely Canadian. It was a joint Canada–US project, which also shows how closely the two economies became linked.
  • Confusing the Rand Formula with the right to strike. The Rand Formula is about union dues: everyone covered by a contract pays dues, even if they do not join the union.
