Life expectancy:  According to Statistics Canada Health Profile 2011, female life expectancy at birth is 80 years in Niagara and 81 years in Ontario. Life expectancy for males was 77.5 years and 82.5 for females.

Age standardization:  Because Niagara has an older population compared to Ontario, we need to adjust the data to take out the age effect and be able to compare apples to apples.  If the age effect is not taken into consideration then the comparison between Niagara and Ontario would not make sense.  All of the data below, when compared to Ontario is age standardized.  It comes from Niagara Region Public Health, Health Story of Niagara http://www.niagararegion.ca/news/publications/hs/default.aspx
