*
We could not calculate health-adjusted life expectancy in 2011 because there was no corresponding Statistics Canada population health survey that included the Health Utility Index Mark-3.
†
Difference between 2011 and 1996 for life expectancy and difference between 2008 and 1996 for health-adjusted life expectancy.
‡
Difference between life expectancy and health-adjusted life expectancy.

Ratio of health-adjusted life expectancy to life expectancy.
