Statistics Canada’s most recent census, which covers the period from 2001-2006, indicates that immigrants to Canada are responsible for two thirds of the country’s population growth. With the total Canadian population swelling to 31.6 million, the Canada-born populace increase of 400,000 was well outdone by the additional 1.2 million immigrants over the five-year span of the census.
Given the country's dwindling fertility rate, Canada has immigration to thank for its robust population growth rate of 5.4 percent, which is the strongest of the Group of Eight industrialized nations. With an average of 240,000 newcomers each year over the census period, Canada’s net migration, per capita, is among the highest in the world at 6.5 migrants per 1,000 people.
Canada's national birthrate of approximately 1.5 children per woman, will not sustain population growth, especially once the bulk of Canada's baby boomers reach the end of their life spans towards 2030. Canada will become 100 per cent dependent on immigration for population growth.
