Paul Gilligan graduated from the Sheridan College Illustration program, and entered the field of Night Security Guarding afterwards. Finding this to be without artistic challenge, he soon began working at a large advertising agency, followed by a stint as staff illustrator at the Ottawa Citizen Newspaper. He has also worked in the fields of aniimation, magazines and comic books, and won several Studio Magazine and IMNA awards for illustration, and a National Newspaper Award for design. He lives and works in Toronto, doing freelance illustration and writing and drawing the syndicated daily comic strip 'Pooch Cafe' since January 2000. Gilligan is also the writer for the comic 'Poptropica', which debuted on 9 June 2014 and is based on the video game of the same name.
