At-a-glance - The impact of poisoning-related mortality on life expectancy at birth in Canada, 2000 to 2016.

Increases in opioid-related mortality have contributed to declines in life expectancy at birth in the United States and British Columbia. Canadian national mortality data from 2000 to 2016 were analyzed to determine the contribution of poisoning-related mortality to changes in life expectancy at birth by age group and sex. From 2000 to 2016, life expectancy at birth increased by almost three years; however, mortality due to unintentional poisonings, including those involving opioids, curbed this increase by 0.16 years. Although a national decrease in life expectancy at birth has not been observed in Canada during this period, current trends suggest that the national opioid overdose crisis will continue to attenuate gains to life expectancy.
