Overview and Study Objectives
The Ontario Tobacco Survey (OTS) is a population-based longitudinal survey of smokers and a cross-sectional survey of nonsmokers in Ontario.
The main survey objectives were to:
- Evaluate and inform the impact of the Smoke-Free Ontario Strategy
- Monitor trends in tobacco-related knowledge and exposures for both smokers and nonsmokers
- Provide baseline and longitudinal data to better understand the processes of, and influences on, smoking cessation and relapse

Applicants should familiarize themselves with the OTS design and questionnaires. Please refer to the OTS Technical Reports above for further details and documentation.
Data were collected by the Survey Research Centre (SRC) at the University of Waterloo between 2005 and 2011. The SRC recruited more than 7,500 smokers and nonsmokers in Ontario to take part in a 15- to 25-minute survey: respondents were asked questions about their smoking behaviours, their thoughts and experiences relevant to tobacco use and secondhand smoke.
Recent smokers were invited to participate in the longitudinal study in which they were re-interviewed approximately every six months for three years.
