He was educated at McMaster University in Hamilton, Ontario where he received the Bachelor of Arts degree in 1972. He then attended Queen’s University in Kingston, Ontario where he received his Bachelor of Laws degree in 1975.

He maintains contact with both universities that he attended. He played football with the McMaster Marauders and the Queen’s Golden Gaels. He was an “All Canadian” Defensive End in 1971 and drafted in the first round of the Canadian Football League. Rather than take advantage of this opportunity he attended Law School at Queen’s University where he continued playing football.
