Sean Harraher was raised in Oakville Ontario Canada. At the age of 4 (1986), his mother brought him to an audition his sister was attending because she could not find a babysitter in time. He was noticed in the waiting room and was cast in a National Colgate commercial alongside his sister that ran for 5 years.
After graduating with a B.A in Humanities from York University in 2006, Sean acted in many commercials as both a hockey player and a football player. He has performed improv with TrailerVision in Toronto. He is an avid Toronto Maple Leafs and Hamilton Tiger Cats fan.
