Canadian Health Survey on Children and Youth (CHSCY)

Detailed information for 2019





Record number:


The Canadian Health Survey on Children and Youth explores issues that have an impact on the physical and mental health of children and youth, such as physical activity, the use of electronic devices, time spent in school and extracurricular activities. Information from the survey will be used to develop programs and policies to help improve the lives of Canadian children and youth.

Data release - Scheduled for March 2020


The main objectives of the Canadian Health Survey on Children and Youth are:

- To provide current, detailed and ongoing health-related information on children and youth at the national, provincial and territorial levels;
- To provide information to support evidenced-based policy and program development and evaluation;
- To support research initiatives on children's health and well-being; and
- To support children's health surveillance programs by providing information on a regular and timely basis.

The data collected will be used by Statistics Canada, Health Canada and the Public Health Agency of Canada, provincial and territorial ministries of health, as well as by other federal and provincial departments. The information collected from respondents will be used to monitor, plan, implement and evaluate programs to improve the health of Canadian children and youth. Researchers from various fields are also interested in the survey data and will use the information to conduct research into the various factors that affect the health and well-being of children and youth in Canada.

Data sources and methodology

Target population

The 2019 Canadian Health Survey on Children and Youth covers the population aged 1 to 17 as of January 31, 2019 living in the ten provinces and the three territories. Excluded from the survey's coverage are children and youth living on First Nation reserves and other Aboriginal settlements in the provinces, children and youth living in foster homes and the institutionalized population.

Based on a comparison with demographic projections from the 2016 Census of Population, the frame for the CHSCY covers at least 98% of the total target population in all provinces and 96% in all Northern territories.

Instrument design

The survey content was developed based on consultation across Canada with key experts and federal and provincial stakeholders. The goal of the consultation was to provide advice to Statistics Canada on what survey content would be relevant for programs and policies and to fill data gaps related to children and youth. The questionnaire was developed by Statistics Canada, in collaboration with the Public Health Agency of Canada and Health Canada.

Qualitative testing by Statistics Canada's Questionnaire Design Resource Centre, using face-to-face interviews and focus groups, was conducted in November 2014, March 2015, November 2015, June 2016 and April to May 2018.


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

The sampling frame for the Canadian Health Survey on Children and Youth is the Canadian Child Tax Benefit file (CCTB).

The sampling units are children and youth aged 1 to 17 years of age as of January 31, 2019.

In terms of geography, the sample is primarily stratified by province. The two exceptions are in the North (the three Territories are grouped together to form a single stratum) and in Ontario (sub-regions of the province's Local Health Integration Networks make up the geographic strata). The sample is further stratified into three age groups: children aged 1 to 4 years old, children aged 5 to 11 years old and youth aged 12 to 17 years old.

The sample size for the survey is 92,170 raw units.

Error detection

Some editing of the data is performed at the time of the interview within the electronic questionnaire. The questionnaire has built-in checks for some out-of-range or extreme values that prompt respondents and interviewers to verify the recorded answer. Flow errors are controlled in the application through programmed skip patterns. For example, questions that do not apply to the respondent are not asked.
