Over the years, several people have provided invaluable input into this study. First, we owe a debt of gratitude to two pioneers. We would not be in the enviable position of having such rich historical data without the work and foresight of the late Dr. Reginald G. Smart, who started the survey many decades ago. Second, we are immensely grateful to Dr. Edward Adlaf whose expertise and innovations contributed significantly to the expansion and transformation of the survey into the renowned study that it is today. We thank both researchers for leading the way and allowing us to continue in their footsteps. Current colleagues who provided support and important contributions include Angela Boak, Christine Wickens, Gina Stoduto, Nigel Turner, Bruna Brands, Kevin Shield and Jürgen Rehm. Former colleagues include Robin Room, Roberta Ferrence, Susan Bondy, Benedikt Fisher, Lise Anglin, Anita Dubey, and Norman Giesbrecht. All have provided valuable guidance and creative insight into the development of the CAMH Monitor over the years. The sampling design and fieldwork were aptly conducted by the Institute for Social Research, York University, and we especially thank Liza Mercier, David Northrup, Hugh McCague, Lily Li, Stella Park, Richard Myles, Tammy Chi, and Greg Hanson for input throughout the project. Special thanks are also owed to Robert Schwartz, Michael Chaiton, Rita Luk, and the Ontario Tobacco Research Unit who collaborated with us during most cycles of the survey. This study was supported, in part, by the Ontario Ministry of Health and Long Term Care (MOHLTC). The views expressed here are those of the authors and do not necessarily reflect those of the MOHLTC.

Background The CAMH Monitor (CM), conducted by the Centre for Addiction and Mental Health (CAMH), is an ongoing monitoring survey of Ontario adults. One of the mandates of the Centre for Addiction and Mental Health, is to provide epidemiological surveillance of indicators related to alcohol, tobacco, and other drug use, as well as physical and mental health. The epidemiological survey research in this program has a tradition of more than four decades. Historically, the survey had a progression from brief face-to-face interview surveys assessing strictly alcohol and other drug use in 1977, to the Ontario Drug Monitor (ODM), which broadened the scope and content of alcohol and other drug use issues in 1996. Starting with 1999, this surveillance program further developed into the CAMH Monitor now fielded continuously and monitoring a wide range of health and mental health indicators. The CAMH Monitor is designed to serve as the primary vehicle for monitoring mental health and substance use issues among Ontario adults – including mental health status, alcohol and other drug consumption, public opinion regarding alcohol and other drug use issues and policies, and impairments and disabilities due to alcohol, drug use, and mental health difficulties. This report describes four important stages of the 2019 cycle of the CAMH Monitor survey: first, the sampling design and procedures used to draw the sample; second, the outcome of the sampling process and the resulting sample quality; third, the data collection, instrument and items; and fourth, the microdata and its characteristics. This report also describes the CAMH Monitor 2019 microdata public use file (excluded from public use datasets are any items with disclosure risk). The CAMH Monitor is based on over 40 years of institutional experience with population monitoring surveys (see Table 1), including the Adult Drug Use series (1977–1991) and the Ontario Alcohol and Other Drug Opinion Survey series (1992–1995). To enhance comparability to earlier surveys, the CAMH Monitor was designed to maintain many of the features of previous surveys, while maximizing data collection. Including the 2019 cycle of the survey, this program of surveillance research represents 34 surveys conducted since 1977, making it the longest ongoing study of adult alcohol and other drug use in Canada and one of the few studies of such duration globally. 2019 CM Metadata User’s Guide Page 1 Table 1.
