The land had been occupied for more than three centuries, since the establishment of the Iroquois mission in 1676, it is only in 1937 that the founding of la paroisse de Sainte-Catherine de Laprairie really marks a territorial organization. In 1973, a demographic boom finally granted the status of town to the village. In 2006, according to the city's official site, there were 17,000 inhabitants in Sainte-Catherine.

The inauguration of the Honoré Mercier Bridge in 1934, and then of the Champlain Bridge in 1962, greatly boosted the local economy.

In the 2021 Census of Population conducted by Statistics Canada, Sainte-Catherine had a population of 17,347 living in 6,909 of its 7,016 total private dwellings, a change of 1.8% from its 2016 population of 17,047. With a land area of 9.37 km² (3.62 sq mi), it had a population density of 1,851.3/km² (4,794.9/sq mi) in 2021.^[6]
