The Health and Welfare department of the federal government completed a report “Charting Canada’s Future” which concluded that Immigration has only a short-term effect on Canada’s age structure. Moreover, increases in immigration to as high as 600,000 per year would have, in the long-term, no impact on the age structure. Even changing the age structure of immigrants from 23% below age 15 to 30% below 18 and then 50% below 15 would have little long-term impact on Canada’s overall age structure.
