I’m now adopting the habit of recording facts and their references so as to have quick access to them in the future.

A slim female majority
Women and girls comprise just over half of Canada’s population. In 2010, 17.2 million females accounted for 50.4% of the total population, continuing a slim female majority that has held for over three decades (Table 1). In the data recorded from 1921 to 1971, the percentage of males was slightly higher than that of females. In 1921, 48.5% of the population was female, rising to 49.8% in 1971. Over the past century, gains in life expectancy have benefited women more than men. Lower mortality rates for females throughout most of the life course contributed to a slightly higher share of females than males in the population. According to the medium-growth scenario of the most recent population projections, the female majority would continue for the next 50 years.
In short: The gender ratio is nearly even, with woman having a tiny .4% advantage.
The overall female and male age distributions in Canada were similar in 2010, with slim but perceptible differences between the youngest age groups and wider differences between the oldest age groups. For example, 48.6% of children under age 10 were girls and 51.4% were boys. In fact the sex ratio at birth, on average, is 105 boys born for every 100 girls. There were roughly equal proportions of females and males in the under-65 age groups in 2010. However, females’ greater life expectancy creates a growing disparity throughout the senior years, with women outnumbering men. For the total Canadian population aged 65 years and older, the proportion of women was 56% in 2010, increasing to 67% for those aged 85 and older and to 80% for centenarians. Since the late 1970s, however, gains in life expectancy have been more rapid for men than for women. If the gap in life expectancy continues to narrow, this could eventually result in a more balanced share of women and men in their senior years. See chapter on senior women for more information.
In short: more boys than girls are born, but females have a greater life expectancy, though men are slowly catching up.
