Data source

The Government of Canada developed the Canadian COVID-19 Antibody and Health Survey (CCAHS), to learn more about longer-term symptoms. The CCAHS covers the period from the beginning of the COVID-19 pandemic until August 31, 2022. A random sample of Canadian adults were surveyed between April 1 and August 31, 2022. The questionnaire asked about new or continuing symptoms 3 or more months after a confirmed or suspected case of COVID-19.

We’ve used this data to produce the reports highlighted here.

Highlights of the second report (Spring 2023)

The second report, Associations between Longer-term Symptoms after COVID-19 and Sociodemographics, Health Characteristics, Period of Infection, and Vaccination Status in Canadian Adults, January 2020 to August 2022, was published in the Spring of 2023. It looked at which groups of adults were more likely to report longer-term symptoms. It also explored risk and protective factors. Since this report was based on the latest CCAHS data, some estimates may differ from those published earlier.

The survey revealed that 17.2% of adults experienced longer-term symptoms after having had COVID-19 (confirmed or suspected), and that certain groups were more likely to report longer-term symptoms, including those who:

The survey also showed that longer-term symptoms were more common among adults who were:

The results presented in this publication are consistent with other studies on longer-term symptoms after getting COVID-19.

Highlights of the first report (Fall 2022)

The first report, Frequency and impact of longer-term symptoms following COVID-19 in Canadian adults, was published in the Fall of 2022.


of adults with a confirmed or suspected infection experienced longer-term COVID-19 symptoms


of adults who experienced longer-term COVID-19 symptoms experienced symptoms for a year or longer


of adults who experienced longer-term COVID-19 symptoms said that their symptoms often or always limited their daily activities

Longer-term symptoms were more common among females (18%) than males (11.6%), and among those who reported severe symptoms when they first got sick (36.4%).

Among adults with longer-term symptoms, the most common were:

Among adults with longer-term symptoms who were employed or attending school, approximately three-quarters (74.1%) missed some work or school due to their symptoms. On average, they missed 20 days.

These results are consistent with those from other surveys and international evidence.

Other initiatives about longer-term symptoms

The Government of Canada is trying to better understand and address the longer-term health impacts of COVID-19. In addition to the CCAHS, other efforts include investments in research through the:
