Note: AAPC = average annual percent change, CI = confidence interval. Results that are statistically significantly different from zero are shown in boldface. *Rates are reported per million population. †The province of Prince Edward Island, the Northwest Territories, Nunavut and Yukon were excluded from the stratified analyses because of the small number of cases.
