During the first year of the COVID-19 pandemic through early 2021, international comparisons showed a wide variation in patterns of mortality across countries.1 Although some countries saw no change in mortality or even fewer deaths than expected, others saw marked increases, such as a 19% increase in Italy, 18% in the United Kingdom and 22% in the United States.1 In Canada, a 5% increase was reported during this early pandemic period.1 A report from the Public Health Agency of Canada suggested differential mortality rates among older adults across Canada’s provinces in 2020.2 An analysis of data from the first few months of the pandemic showed a twofold variation in excess mortality rates across regions of England and Wales,3 whereby excess mortality refers to the degree to which observed deaths exceed expected deaths (based on modelling of previous years of age-specific mortality).4,5 Excess mortality is a useful indicator of the populationwide effects of the COVID-19 pandemic. Given the observed variation across and within other countries, variation across provinces and territories in Canada is likely. This analysis uses publicly available data to explore excess mortality related to COVID-19 in the Canadian provinces from the start of the pandemic in March 2020 through October 2021 to shed light on the population-wide effects of the pandemic and variations across the country.
