↵* The standardized ratio was derived by dividing the observed and age-adjusted expected counts.
↵† Goodness-of-fit testing the null of no differences between observed and expected values.
↵‡ The population group “All other” includes various population groups that individually had less than 5 counts.
↵§ The official languages include French and English.
