“…For example, a review of excess mortality and COVID-19-related mortality across Canadian provinces showed substantial variation and, in some cases, poor alignment between these 2 measures. 25 Finally, surges of cases and deaths do not occur simultaneously across countries, likely requiring the pandemic to run its full course before stronger inferences about causes and effects can be drawn. 26 Our review of a broad range of metrics related to pandemic control and outcomes across G10 nations does, however, provide a stark picture of the varying approaches taken by governments and the related impact of the virus and mitigating interventions over the course of the pandemic.…”

The first known diagnosis of SARS-CoV-2 infection in Canada was in a patient in hospital in Toronto on Jan. 25, 2020. 1 At the time, few anticipated the intensity and duration of the COVID-19 pandemic, which has presented health systems and governments globally with challenges not encountered in a century. Through the first 2 years of the pandemic, the Canadian public bore the substantial burden of a range of public health measures, while maintaining a high degree of social solidarity with respect to policies such as the need for vaccines. 2 As the pandemic continues into its third year, a reflection on how Canada compared with similar nations during the first 2 years of the pandemic may allow both the public and our governments to better contextualize Canada's response to and experience of the pandemic. We consider how Canada compared with peer nations on several broad indicators that reflect the impact of both SARS-CoV-2 and measures to contain it, using publicly available data. How can we compare Canada with other countries?We sought to compare Canada's rates of SARS-CoV-2 infection, COVID-19-related and all-cause excess deaths, SARS-CoV-2 vaccination rates, pandemic-related societal restrictions and economic impacts of the pandemic with those of similar countries (see Box 1 for our rationale for metrics used in this analysis). We used data from Feb. 4, 2020, to Feb. 8, 2022, from several international data repositories: Our World in Data; the Organisation for Economic Co-operation and Development (OECD); the United Nations Educational, Scientific and Cultural Organization (UNESCO); and the International Monetary Fund. [14][15][16][17] We applied 3 criteria to choose comparator countries. First, similarity in economic and political models, given the policy and governance challenges of implementing public health restrictions in democracies, especially policies that affect personal liberty. Second, we considered similar per-capita income levels to be important, given this metric's correlation with health system capacity, which is critical to pandemic response and is in turn relevant for factors such as public health infrastructure to implement screening and vaccination, and hospital-and intensive care unit-based care for those with severe disease. Lastly, we considered population size, to a certain extent, given the logistics of population-wide pandemic management. We sought the largest defined grouping of countries that existed in prepandemic times that would fulfill these criteria. Given these considerations, we chose to compare the Group of 10 (G10) countries: Canada,

“…102,103 By October 2021, Ontario experienced a 6% increase in mortality over pre-pandemic rates of which 86.5% were COVID-19 related. 104 In England, non-COVID-19-related mortality among people with diabetes was 11% higher than pre-pandemic and was highest among those who did not complete diabetes care processes in the preceding two years. 105 Although overall visit volumes returned to pre-pandemic levels within six months, there is evidence across health systems of delayed diagnosis and delayed care.…”

About Us: The Ontario COVID-19 Science Advisory Table is a group of scientific experts and health system leaders who evaluate and report on emerging evidence relevant to the COVID-19 pandemic, to inform Ontario's response. The Science Advisory Table's mandate is to provide summaries of relevant scientific evidence to public health and health care professionals, as well as the general public, by integrating information from existing scientific tables, Ontario's universities and agencies, and the best global evidence. The Science Advisory Table is hosted by Public Health Ontario (PHO). Aligned with PHO's mandate, the Science Advisory Table provides credible and independent scientific and technical advice to inform government and the broader public about COVID-19 and to help prepare for and respond to future public health emergencies.

“…CMAJ has been made aware of an error that occurred in the May 30, 2022, issue. 1 In Figure 1, the excess and COVID-19 mortality rates are indicated as being per 100 000 population per week on the y-axis of each graph, but rates were calculated per 1 000 000 population per week.…”
