The emergence of COVID-19 variants of concern and community response to shifting public health measures continue to influence the course of the COVID-19 pandemic in Canada and worldwide.

To understand the direct and indirect consequences of the pandemic, it is important to measure excess mortality, which occurs when there are more deaths than expected in a given period. It should be noted that, even without a pandemic, there is always some year-to-year variation in the number of deaths in a given week. As such, the number of expected deaths should fall within a certain range of values. There is evidence of excess mortality when weekly deaths are consistently higher than the expected number, but especially when they exceed the range of what is expected over several consecutive weeks.

Provisional data show there were an estimated 53,741 excess deaths in Canada from the end of March 2020 to the end of August 2022, 7.6% more deaths than expected had there not been a pandemic. During this period, at least 42,215 deaths were directly attributed to COVID-19.

The third week of January 2022 was the deadliest week in Canada since the pandemic began, with 27% more deaths than what would have been expected​

Since the emergence of the Omicron variant in late November 2021, there have been two periods of significant excess mortality observed so far. Nationally, there were 8,286 more deaths than expected from the beginning of January 2022 to the end of February 2022, or 16.8% more deaths than expected over that period. During this period of excess mortality, the highest number of deaths and the highest weekly rate of excess mortality of the pandemic were recorded in the third week of January 2022, with 26.8% more deaths than expected. Put differently, over one in five deaths during this week would not have been expected. In the spring, there were 2,357 excess deaths observed from the middle of April 2022 to the middle of May 2022, or 8.4% more deaths than expected. While the first period of excess mortality in 2022 was driven by excess mortality in Quebec and Ontario, the most recent period of excess mortality was driven by excess mortality in the three westernmost provinces. In fact, Alberta and British Columbia had higher than expected weekly deaths through much of 2022.
