This page and its charts will not be updated between Sept. 17 and Sept. 21. Regular updates will resume Sept. 22.
Data on COVID-19 is largely focused on the international, national or provincial level, but statistics. compiled by CTV News illustrate how the coronavirus is affecting Edmonton and its individual communities.
Alberta Health Services divides Edmonton up into 15 health subzones named for their home communities.

Since early April, the province has provided daily updates on the number of COVID-19 active cases, recoveries and deaths in each of those subzones as well as totals for the city itself.
The province provides data Monday through Friday, except for holidays. Where possible, data from weekends and holidays are included in the visualizations below.
This page is divided up into five sections: overall city data, subzone (community) level data, testing data, age data, and methodology.
Scroll down or follow the links below to navigate to each section.
CITY OF EDMONTON
Unless otherwise specifically indicated, numbers on this page are for the city itself and not the zone.
See the methodology section below for how AHS defines a recovery from COVID-19.
Note, the 15 subzones cover the vast majority, though not all, of the area inside the city's coroporate boundaries as seen in the map above.
Scroll down or follow these links to see how the number of total cases, active cases, recoveries and deaths have changed over time in individual subzones:
- Abbottsfield, Bonnie Doon, Castle Downs
- Duggan, Eastwood, Jasper Place
- Mill Woods South & East, Mill Woods West, Northeast
- Northgate, Rutherford, Twin Brooks
- West Jasper Place, Woodcroft East, Woodcroft West
- Beaumont, Devon & Leduc, Fort Saskatchewan
- St. Albert, Stony Plain & Spruce Grove, Sherwood Park

Testing data for specific cities isn't yet available so these graphs display data from the Edmonton Zone as opposed to the city itself.
Testing for asymptomatic individuals is also being made available at an increasing number of pharamacies across the province. See Edmonton locations that are offering testing here.
Test positivity percentage is a statistic provided by the province that takes into account the processing time of between two to seven days needed to determine the outcome of the test.
Similar to testing data, age-specific data is only available relative to AHS health zones, and not to specific cities.
The above heat map shows the Edmonton zone's evolving active case count since the start of July, grouped by age ranges used by AHS.
The graphs above were assembled using two versions of the province's interactive data map, each with different borders.
The city-specific graphs draws data from the city of Edmonton as defined by its geographic corporate boundaries.
The community-level graphs draw data taken from the province's 15 Edmonton-area health subzones.
Their boundaries closely resemble the city's borders but with some exceptions. As a result, some areas within Edmonton's corporate boundaries, largely near the city's southern boundary, are included in suburban health zones.
Cases are attributed to the subzone of a patient’s primary residence. You can see population estimates for each subzone here.
The updated daily case count reflects the number of new, active cases (people who are now newly ill with COVID-19).
The daily change in active cases are determined by subtracting the number of newly recovered cases from the number of new cases. A positive value represents an increase in net active cases, with a negative value indicating the opposite.
The province often revises data, and reclassifies cases to other health zones or subzones which can cause a sudden rise or drop in cases for a given location. Case counts can rise or fall retroactively as probable cases are taken into account.
Reclassifications can occur for a number of reasons, including:
- A patient's contact information was updated to reflect his or her proper address.
- Further testing revealed a patient did not, in fact, contract COVID-19.
- Data entry errors.
The province published new numbers daily March, April, May and June, with subzone data being available since early April. Starting the weekend of July 4, the province will release updated data on weekdays only, with no scheduled updates on holidays and weekends.
Recoveries are defined by Alberta Health Services as follows:
- A return to health after 14 days of isolation for those with COVID-19 but who experienced only mild symptoms.
- If hospitalized due to COVID-19, anyone who does not require additional hospitalization or treatment in the 10 days after they left the hospital.
- If tested, such as a health care worker, two negative tests at least 24 hours apart.
It's also noteworthy that in data parlance, a recovery is someone who contracted COVID-19 but didn't die due to the virus. A recovery is not necessarily synonymous with a return to full health as many patients report severe symptoms long after their infections have cleared.
