COVID-19 and deaths in older Canadians: Excess mortality and the impacts of age and comorbidity

The coronavirus disease (COVID-19) pandemic has had unprecedented consequences for Canada's aging population with the majority of COVID-19 deaths (approximately 80% during 2020) occurring among adults aged 65 years and older. Both advanced age and underlying chronic diseases and conditions contribute to these severe outcomes.

Excess mortality refers to additional mortality above the expected level (based on mortality in the same period in the preceding year or averaged over several preceding years in the same population). This measure allows for the measurement of death directly and indirectly related to COVID-19 and provides a summary measure of its whole system impact in addition to its impact on mortality.
