摘要:As is well known, Canada¡¯s population is aging:
the total fertility rate has been below
the natural replacement level since the early
1970s, life expectancy has continued to rise, and
the baby boomers are hitting middle age, and
will start to retire in less than 20 years. Thus
population and labour force growth rates are on
long-run downward paths and the proportion of
older people is projected to increase sharply in
the next century. What is not well known is the
impact of immigration on these trends.
