EDMONTON -- Data on COVID-19 is largely focused on the international, national or provincial level, but statistics compiled by CTV News illustrate how the coronavirus continues to spread through Edmonton and its individual communities.

Alberta Health divides the city of Edmonton up into 15 health subzones roughly 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 city of Edmonton is distinct from the Edmonton health zone, which includes communities beyond the city itself. Some data, including hospitalizations and test positivity, is provided only at the zone level. 

This page is built across eight sections that highlight different aspects of the pandemic's changing toll on Alberta. Scroll down or follow the links below to navigate.

City case status | Vaccines | Hospitalizations and deaths | Spread | Testing | Age data | Variants Community (subzone) data


The city of Edmonton has seen its active case count fluctuate from a few dozen to more than 8,000 over the course of the pandemic. Click the legend in the graph above to filter the city's cases by status.

The above interactive map displays current active case counts by city community (subzone). Note, the 15 subzones cover the vast majority, though not all, of the area inside the city's coroporate boundaries.

Darker shaded regions represent areas with the most active cases. Click on a subzone for information on population, actives adjusted for population and also a link to historical case status data.

The data race above shows how Edmonton's active case count through the pandemic compares to those in other Alberta municipalities.

The number of active cases represents the number of people infectious with COVID-19. The value can can go up or down depending on the number of new cases and new recoveries on a given day. 

A recovery is someone who contracted COVID-19 but didn't die due to the virus. It is not synonymous with a return to full health as many "long hauler" patients report severe symptoms well after their infections have cleared.

The graphs below display daily new cases and the daily change to the city's net active case count.

Alberta Health defines a recovery 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.

COVID-19 vaccinations promise a way out of the pandemic, in time.

Vaccines have been distributed in Alberta since late 2020 with the number of shots given out increasing through the early part of 2021.

See the above data race for vaccination rates in subzones within the city of Edmonton. Click here for a similar graphic showing all 132 subzones across Alberta.

Four vaccines, developed by Pfizer, Moderna, AstraZeneca and Johnson & Johnson, have been authorized for use in Canada to date.

The federal government is responsible for securing the vaccine supply while the individual provinces are tasked with distributing those supplies to their populations.

Most vaccines require a second shot, and possibly a further booster shot months or years later to ensure continued immunity.

Alberta began rolling out its vaccination plan in late 2020. By January 2021, Albertans over the age of 75 were eligibile to book a shot. Vaccine eligiblity has grown from mid-March onwards, expanding on May 10 to all Albertans born in 2009 or earlier.



Hospitalizations have been reported province-wide since the start of the pandemic, and by health zone since early May 2020, but not by individual cities.

Tracking hospitalizations is an important indicator of how severely the pandemic is affecting Albertans as well as how the coronavirus is taxing the province's health care system. 

Cases are assigned a location by a patient's home address, but hospitalizations are reported based on the location of hospitalization.

The province has said the system's capacity to handle COVID-19 patients can be increased to 425 ICU beds, but at the cost of fewer beds, staff and other resources for other patients and procedures, including the cancellation of non-esential surgeries and medical procedures.

Both of those are signficantly about the province's general ICU capacity of about 170 beds.

Deaths are outlined below by city boundaries, though they are also reported by health zone and subzone. 

Deaths do not necessarily occur the day before they are reported. They are tracked below by day of reporting as the province doesn't report the actual date of death by city.



Testing data for specific cities isn't available so the above graph displays data from the Edmonton Zone as opposed to the city itself. 

The Edmonton Zone had a population of just over 1.4 million people in 2018, according to AHS. The same year, the province estimated the city of Edmonton's population at just over 1 million people.

Test positivity percentage provides insight into what proportion of daily tests are returned with positive results. It can generally be calculated by dividing the number of positive results by number of tests, but Alberta Health cautions that confirmed cases can occasionally appear the reporting system two to three days later.

The precise figure takes that delay into account and is provided by the province.



The reproduction value, or R-Value, measures the expected number of cases directly caused by one case. It informs how rapidly the coronavirus is spreading and has been cited by the premier as key metric in determining government policy around restrictions. 

The value can be calculated using one of several different models which estimate a number of factors around the virus and population.

A value of one means an infected person will infect one other person, on average. A value above one means the spread is growing. A value below one means the spread is slowing.

The province has provided the statistic for the province as a whole as well as for the Edmonton and Calgary health zones (not cities) and the rest of Alberta on a weekly basis since Dec. 8, 2020.



Similar to testing data, age-specific data is only available relative to 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. 

The below bar charts show the most recent data of case outcomes by age group since the start of the pandemic.



Variants occur when a virus develops a set of mutations that change its genetic code enough that it reacts differently than the original strain, but also not enough that it becomes its own virus.

A series of variants that developed in late 2020 drew particular concern due to being more transmissible, and in some cases more deadly, than the initial strain.

These variants are identified by the location of their discovery or through letters and numbers, but efforts have been made to rename them to avoid stigmatizing entire cities and countries.

Confirmed COVID-19 cases had been screened for variants since Feb. 1, 2021.

Alberta Health notes the need for a second screening delays the reporting of variant cases by up to two days, though delays in other provinces are often much longer.

On April 11, Alberta Health data showed that for the first time, variants made up a majority of the province's active COVID-19 cases.

On May 1, the province announced it had stopped testing all samples and was screening only a representative samples from specific populations in order to maintain capacity. 

The low number of samples screens negated the value of the raw numbers, so the above graph displays variant types as a proportion of all daily samples screened in an effort to identify relative growth patterns.

Alberta Health said it was resuming screening all confirmed cases again starting June 1.

Alberta Health has said variants have become, and will continue to be, the dominant strain in Alberta, meaning that nearly every new case should be assumed to be a variant.
