Variables

The general aim of the survey is to learn as much as possible about the SARS-CoV-2 virus, how it affects overall health, how it spreads, and whether Canadians are developing antibodies against it.
The objectives of the survey are to:
- estimate how many Canadians test positive for antibodies even if they have never had symptoms of COVID-19
- better understand the social distancing behaviours of Canadians and their general health during the pandemic.
It also aims to shed light on immune responses to SARS-CoV-2 in a diversity of communities, age brackets, populations, and occupational groups across the nation.

Data Collection Event
In the first part, information was collected from an electronic questionnaire about sociodemographic characteristics, general health(chronic conditions, health behavior and health assessment) and exposure to COVID-19(symptoms, health status, risk of contraction and risk factors).
In the second part, a blood sample was collected through an at-home finger-prick blood test to determine the presence of COVID-19 antibodies.

Within each household, one individual aged 25+ was selected based on specific instructions within the letter they received (or provided by the interviewer if they responded by phone). The instructions used the age of household members to determine who was selected, and varied from one household to another. For some households, the oldest member was selected, others the second oldest, or the youngest, etc. These letters were randomly assigned to the selected dwellings ensuring that the selected individual from within the dwelling was random.
