Data sources and methodology

Target population

The target population for the survey is non-institutionalized persons 18 years of age or older, living in Canada's ten provinces, who are not members of collectives or living on reserves.

Instrument design

The content for the Survey on COVID-19 and Mental Health electronic questionnaire was drafted in consultation with Statistics Canada's Centre for Population Health Data, as well as the Public Health Agency of Canada.

The questionnaire underwent cognitive testing in the form of in-depth interviews in both of Canada's official languages, conducted by Statistics Canada's Questionnaire Design Resource Centre. The goal of the qualitative study was to test the survey content.


This is a sample survey with a cross-sectional design.

Sampling unit
The SCMH sample has a two-stage design: the sampling unit for the first stage is the dwelling, and the sampling unit for the second stage is the person.

Stratification method
The SCMH frame was stratified by province, and a simple random sample of dwellings was selected within each province.

Sampling and sub-sampling
Sufficient sample was allocated to each of the provinces so that the survey could produce provincial level estimates. An initial sample of 36,000 dwellings was selected and sent to collection.
