A campaign that returns to Ottawa streets this fall, just as students settle into their school year, sends hard-hitting messages to people who might take advantage of drunk women and men.

The "don't be that guy" posters is a partnership between Crime Prevention Ottawa and the Ottawa Hospital.

The two agencies decided to put ads on the buses after a successful "don’t be that guy" campaign in local bars.
