Effects of Extending Alcohol Sales Hours In Licensed Establishments

Ontario, Canada, amended the Liquor License Act to extend the hours of alcohol sales and service in licensed establishments from 1 to 2 a.m. in an effort to reduce alcohol-related problems.

To determine if the extention of open hours had the intended effect, police data from two Ontario cities (London and Windsor) were compared before and after the legislation.

Both cities experienced significant overall reductions in impaired driving charges, although none for assault charges, aggregated over the 11:00 p.m. to 4:00 a.m. time period after the drinking hours were extended.

This finding is consistent with other research demonstrating either a reduction or no change in alcohol-related problems after alcohol sales hours are extended.
