Impacts of drinking-age legislation on alcohol-impaired driving crimes among young people in Canada, 2009–13

Minimum legal drinking age (MLDA) laws place age-based restrictions on the consumption, purchase and possession of alcohol among young people. Canada's MLDA is 18 years in Alberta, Manitoba and Québec and 19 in the rest of the country. In this article, the authors compare the number of alcohol-impaired driving (AID) crimes committed by drivers slightly older than MLDA with those committed by those slightly younger than MLDA. They employ a regression-discontinuity approach and draw on the Canadian 2009–13 Uniform Crime Reporting Survey's police-reported AID incidents. Among the results are the findings that, in places where the MLDA is 18, individuals slightly older than the MLDA have increased AID incidents, compared with those slightly younger than the MLDA. The authors suggest an association between alcohol-impaired driving offenses among young Canadian drivers and the release from drinking restrictions.
