别拿神马都扯到党派上，加拿大人口老龄化的根本原因是历史上的BABY BOOMER造成的，问问你自己的孩子或看看加拿大历史书，增加自己的常识再作评论。

Baby Boom
Canada's birthrate ballooned from the end of the Second World War until about 1965, thanks to improving economic conditions and a related trend over the same period toward larger families.
Canada's birthrate ballooned from the end of the Second World War until about 1965, thanks to improving economic conditions and a related trend over the same period toward larger families. The result was a 20-year bulge in the population known as the baby boom, a generation whose demographic influence has shaped Canada's economy and society and continues to do so as its members age and move into retirement.
The Birthrate Rises
Although an official definition of the baby boom does not exist, it generally describes a period of increased birthrates lasting from 1946 to about 1965. The Great Depression of the 1930s had prolonged the decline in Canada's birthrate (see Population), as it had in most Western countries. The low point in Canada was reached in 1937, when the gross birthrate (the annual number of live births per 1,000 inhabitants) was 20.1. Improved economic conditions caused a recovery that began to accelerate during the Second World War. By 1945 the birthrate had risen to 24.3; by 1946 it had jumped to 27.2, and it remained between 27 and 28.5 per 1,000 inhabitants until 1959, after which it began to gradually decline.
More Marriages, More Children
The baby boom began with the children whose birth their parents had postponed during the Depression, but two other factors also contributed to the boom.
First, a larger proportion of adults married, and those who did had more children. Women born between 1911 and 1912 had an average of 2.9 children, whereas those born between 1929 and 1933 had an average of 3.3. These two generations are separated by 20 years. Between the older and the younger, the number of children per woman increased by 13%.
Second, more than half of baby-boom births can be attributed to what demographers call "timing phenomena." More adults began marrying at a younger age (the median age for a woman's first marriage was 23.2 years in 1940 and 21.1 years in 1965), and between the end of the Second World War and 1965, young couples tended to have their children during the first few years of married life.
The annual number of births in Canada rose from 253 000 in 1940 to 479 000 in 1960, but dropped to 419 000 in 1965. Over this period of 25 years, the baby boom produced about 1.5 million more births (there were about 8.6 million overall) than would otherwise have occurred, an increase of more than 18%.
By 1965, however, people were marrying at a later age and were waiting longer to have children, partly because more women were entering the workforce, and partly because there was general access to better methods of birth control.
