*Expected rates are adjusted for age, and we used age groups of 5 years for people aged 15 in Canada in 2006, unless otherwise specified.

†Standardized to the Ontario population in 2006.

‡Includes women only.

§These are diseases that are attributable in whole or in part to the risk factor as defined by Statistics Canada,41 and these data include people aged 25 and older only.

¶For some age strata, the number of deaths was too low for Statistics Canada to report (i.e., < 5), and we assumed the maximum number of 4 expected deaths to provide the most conservative estimate of the standardized mortality ratio.

**To decrease the risk of identifying individuals, we indicated 5 in cells in which there were 5 or fewer observed deaths and left the number of expected deaths blank.
