lifting during the 1960s, the South Asian Canadian population witnessed rapid growth in the mid-late 20th century, increasing from 67,925 persons or 0.3% of the total Canadian population in 1971 to 723,345 persons or 2.5% of the total Canadian population in 1996; this growth was primarily attributed to mass immigration. Attributed to the large increase in immigration during the era, Ontario overtook British Columbia by 1971 as the province with the largest population of individuals with South Asian ancestry in Canada. The South Asian population in Ontario grew from 30,920 persons in 1971 to 427,470 persons by 1996; in British Columbia from 18,795 persons in 1971 to 165,010 persons by 1996. During the same era, British Columbia would continue to be the province with the largest proportion of South Asian Canadians, increasing from 0.9% in 1971 to 4.5% by 1996, while the South Asian Canadian share of the total population in Ontario grew from 0.4% in 1971 to 4.0% by 1996.

Immigration restrictions prior to the 1960s severely limited South Asian population growth in Canada. British Columbia was the only province to have notable populations during the early-to-mid 20th century, peaking in 1908 with approximately 5,209 persons, forming 1.6% of the provincial population. Tightened immigration restrictions, heightened racial tensions, along with migration to the United States or a return to the subcontinent prompted a population decline in the following years; the 1911 census counted 2,292 persons of South Asian ancestry in British Columbia, comprising 0.6% of provincial population. This was followed by another population decline in the ensuing 10 years with 951 persons of South Asian ancestry in British Columbia or 0.2% of the total population in 1921. During the ensuing 30 years, a population stagnation followed by a slow gradual increase in the South Asian Canadian population principally stemmed from natural growth, as immigration from the subcontinent has been essentially halted since 1908 due to the Continuous journey regulation. In the 1950s, country quotas were introduced and permitted sponsorship of relatives, thus resulting in the first relatively major increase in the South Asian Canadian population since prior to 1908.
