The post-war period was one of growing prosperity and deep social changes across the country. Cities everywhere underwent profound transformations, with the growth of high-rise downtowns, the democratization of the automobile and the expansion of the suburbs. Québec City was no exception to these trends.

In the province, this period became known as the Quiet Revolution. It was also marked by the steep decline of the Catholic Church's influence on society and the introduction of extensive universal public services. Québec City, where a large proportion of the population was now composed of civil servants, was all the more impacted by these social and economic changes. Parallelly, newcomers of various origins settled in the city, diversifying its population.
