-
Members of the Angus Reid Forum (ARF) were invited to take an online survey on symptoms associated with SARS-CoV-2 and testing histories. The first phase selected adults stratified by age, sex, education, and region, by census metropolitan area to match the national demographic distribution, with oversampling of adults age 60 years or older. Forum panel members who lived in 17 pre-defined public health regions (out of 93 in Canada) who had not already enrolled in the study were recruited later.
