A heat map of coronavirus cases in Canada

COVID-19 case numbers are changing quickly in Canada. Maclean's has created this heat map to present all the crucial information across provinces in one place.

As the COVID-19 pandemic sweeps across Canada and the world, the numbers are changing quickly. Maclean’s has created this heat map to present all the crucial information on one page. Numbers were last updated as of March 31 at 7:30 p.m. EDT, and include the latest data from the federal, provincial and territorial governments. (Maclean’s is also keeping track of Canada’s progress in “flattening the curve”—see that here.)

The colouring of this heat map reflects the number of COVID-19 cases per 100,000 population. In addition, you can use this interactive map to click on each province and territory to see:

  • Number of confirmed COVID-19 cases
  • Number of confirmed COVID-19 cases per 100,000 population (reflected in the colour coding of the map)
  • Number of deaths
  • Number of tests
  • Number of tests per 100,000 population

Including the number of COVID-19 cases as well as the number of tests on a “per 100,000 population” basis allows readers to easily compare the situation across Canada in a way that raw numbers can’t. Provinces with a large population will usually have higher raw numbers.

For instance, figures on March 23 put Ontario at 425 cases and Yukon at just two. Yet, by calculating their cases per 100,000 population, Yukon has 4.9 cases per 100,000 population while Ontario has 2.9.

For the record, here are the national statistics for Canada:

  • No. of cases: 8,591
  • No. of cases per 100,000 population: 23
  • Number of deaths: 101
  • Number of tests: 236,000
  • Number of tests per 100,000 population: 623

On occasion, Maclean’s breaks out COVID-19 data into new charts. Currently, there is a great emphasis on testing as a way to get a handle on the spread of the disease. As the raw numbers recording the amount of testing varies dramatically depending on the province and territory, as well as its size and outbreak status, it’s helpful to consider the numbers on a per-100,000-population basis, so as to compare how much of each jurisdiction’s population is, in fact, being tested. Provinces and territories are grouped by region: the North, Western, Atlantic and central Canada.
