Canadian immigration policies are still evolving. In 2008, Citizenship and Immigration Canada made significant changes to streamline the steady flow of immigrants. Those changes included reduced professional categories for skilled immigration as well as caps for immigrants in various categories.[7] Additional changes were made in April and May 2017.[1] In November 2017, Immigration Minister Ahmed Hussen announced that Canada would admit nearly 1 million permanent residents to Canada over the following three years, rising from 0.7% to 1% of its population by 2020.[8] This increase was motivated by the economic needs of the country facing an aging demographic, with the number of senior citizens expected to double by 2036 alongside a decline in the proportion of working-age adults.[8]
