Canadian Tobacco Use Monitoring Survey/Canadian Tobacco, Alcohol and Drug Survey

The Canadian Tobacco, Alcohol and Drugs Survey (CTADS) replaced CTUMS beginning in 2013. CTADS/CTUMS is conducted by Statistics Canada with the cooperation and support of Health Canada. CTUMS (1999-2012) was developed to provide Health Canada and its partners with timely, reliable, and continual data on tobacco use and related issues. Beginning in 2013, new content covering alcohol and drug use was added to CTUMS to create CTADS. Data are collected via telephone interviews, conducted from February to December in each survey year (annually for CTUMS; every 2 years for CTADS). The samples for CTADS/CTUMS are selected using a stratified random sampling procedure, and include the population of Canada aged 15 years and over, excluding residents of Yukon, Northwest Territories and Nunavut, as well as full-time residents of institutions and residents without telephones (or with cell phones only, prior to 2015).

Youth Smoking Survey/Canadian Student Tobacco, Alcohol and Drugs Survey

The Canadian Student Tobacco, Alcohol and Drugs Survey (CSTADS; called the Youth Smoking Survey (YSS) prior to 2014-15) is an important surveillance tool that provides Health Canada, its partners and stakeholders, as well as the Canadian public, with timely and reliable data on tobacco, alcohol and drug use, and related issues among Canadian students. CSTADS/YSS is funded by Health Canada and has been implemented biennially since 2004-05 by the Propel Centre for Population Health Impact at the University of Waterloo, in collaboration with researchers across Canada. The YSS was also implemented by Health Canada in 1994 and 2002. In each survey cycle, schools are randomly sampled within each of the 10 provinces, using a stratified single-stage design, to ensure a provincially and nationally generalizable sample. Within each participating school, all students in grade 6-12 classrooms (including grade 5 and excluding grades 10-12 prior to 2006-07) are invited to complete the CSTADS questionnaire. The sample excluded residents of the Yukon, Nunavut and Northwest Territories, residents of institutions, and those attending schools on First Nations reserves, special needs schools (e.g., schools for visually- or hearing-impaired individuals) or schools located on military bases; schools that did not have at least 20 students enrolled in at least one eligible grade were also excluded. The provinces of New Brunswick and Manitoba did not participate in CSTADS in 2010-11 and 2012-13, respectively. The 2014-15 CSTADS did not achieve a generalizable sample of students in New Brunswick; therefore, provincial estimates for NB are not reported, although NB is included in the national estimates.
