He grew up having two brothers and spent his childhood working fields, moving hay, and playing baseball, hockey, and scrapping with local kids. As a young boy, he aspired to become a professional baseball player. He attended local schools in the area before moving to Toronto at the age of 19 to pursue an acting career.
