The Canadian Community Health Survey (CCHS) is conducted by Statistics Canada. The survey provides cross-sectional (at one point in time) estimates of the factors related to health status, health care utilization and health determinants for the Canadian population. The survey contains questions on a wide range of health topics, including: physical activity, height and weight, smoking, exposure to secondhand smoke, alcohol consumption, general health, chronic health conditions, injuries, use of health care services and related socio-demographic information. The target population of the CCHS includes household residents in all provinces and territories, with the exclusion of populations on Indian Reserves, Canadian Forces Bases, and some remote areas.
Prior to 2007, data collection occurred every two years on an annual period. Data are available for the 2000/01, 2003 and 2005 periods. In 2007, major changes were made to the survey design with the goal of improving its effectiveness and flexibility through data collection on an ongoing basis. Data collection now occurs every year, rather than every two years as was the case prior to 2007.
CCHS data reported on this website were obtained using the Ontario Share File provided to health units by the Ministry of Health and Long-Term Care. The Ontario Share File has a slightly smaller sample size than the Master File and Public Use Micro File (PUMF). This is because respondents must agree to share their information with the province to be included in the Share File.
