To compile Canadian figures, CBC/Radio-Canada monitors press releases and communications provided by various levels of government, including health agencies. Regional data is generally made public only after the provincial data. Therefore, there may be a delay before the total number of confirmed cases, recovered cases and deaths within each region is equal to the total provincial number. For Quebec regions, the number of recovered cases is not available.

On July 17, 2020, the way to estimate the number of recovered people in Quebec changed. We used figures from the Institut national de santé publique du Québec to correct our historical data to account for this change.

Historical data for Canada and its provinces before March 14, 2020 comes from the Johns Hopkins University, which collects its data from various sources, including the daily reports of the United Nations' World Health Organization (WHO). After March 14, 2020, historical data is collected through our own compilation. We use Eastern Daylight Time (EDT).

International figures are provided from the John Hopkins University and updated daily around 8pm. Before August 10th, 2020, we used figures from the website Worldometers.info/coronavirus.

For the regions of Quebec and some countries (Spain, Sweden, the Netherlands and the United Kingdom), the number of recovered people is not available on the website of the Institut national de santé publique du Québec or John Hopkins University.

Repatriated Canadian are passengers trapped on the Diamond Princess cruise ship in Japan. They were quarantined at the military base in Trenton, Ontario, after returning to Canada. However, one of these Canadians was unable to return to Canada and died in Japan. He is not counted in the Canadian total number of deaths in this dashboard. A Canadian also died in Brazil and is not counted in the Canadian numbers.

For the graph entitled Daily cases, you can choose between a linear vertical scale (default) or a logarithmic scale. The linear scale increases from unit to unit (1, 2, 3, 4, etc.), while the logarithmic scale is exponential (1, 10, 100, 1000, etc.).

To calculate the rates per 100,000 people, we use figures from the Institut de la statistique du Québec for the regions of Quebec, those from Statistics Canada for the provinces, and projections from the United Nations and the World Bank for the others countries.
