The new immigration regulations introduced in 1962 eliminated overt racial discrimination from Canadian immigration policy. Skill became the main criteria for determining admissibility rather than race or national origin. The classes of sponsored immigrants were expanded so that all Canadian citizens and permanent residents could sponsor relatives for immigration. However, an element of discrimination remained as only Canadian immigrants from preferred nations in Europe, the Americas and select countries in the Middle East were permitted to sponsor children over the age of 21, married children and other members of their extended family.
