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 Ontario adults are interviewed each year, using random-digit-dialling. The survey consists of 12 independent monthly surveys (January - December).
