In 1972, all South Asians were expelled from Uganda, including 80,000 individuals of Indian (mostly Gujarati) descent. Canada accepted 7,000 of them (many of whom were Ismailis) as political refugees. From 1977–85, a weaker Canadian economy significantly reduced South-Asian immigration to about 15,000 a year. In 1978, Canada introduced the "Immigration Act, 1976", which included a point-based system, whereby each applicant would be assessed on their trade skills and the need for these skills in Canada. This allowed many more Indians to immigrate in large numbers and a trickle of Goans (who were English-speaking and Catholic) began to arrive after the African Great Lakes countries imposed Africanization policies.
