CAMH Monitor Survey

The CAMH Monitor, first conducted in 1977, is the longest ongoing addiction and mental health survey of adults in Canada. The survey is designed to serve as the primary vehicle for monitoring substance use and mental health problems among Ontario adults. The CAMH Monitor provides epidemiological trends in alcohol, tobacco, and other drug use, problem use, public opinion regarding drug issues and policies, and mental health among Ontarians.

About 3,000 to 5,000 Ontario adults are interviewed each year using random digit dialling. The sample is considered representative of Ontarians aged 18 years and older (about 10 million Ontarians). Your household may be randomly selected to participate in our survey.

To learn more about the CAMH Monitor and to get answers to questions you may have, see our Frequently Asked Questions (FAQs).

The CAMH Monitor report
