His vocation as a volunteer extends from his experience during his varied and influential career as an educator, an administrator, a scientist and a federal politician. While President and Vice-Chancellor of the University of Guelph, he played a pivotal role in converting an agricultural, veterinary sciences and home economics institution into a broadly-based university. He also helped to advance international education and development research while a Member of Parliament and as a Minister of the Crown. In retirement, he volunteers his time to fund-raising efforts for charitable organizations, most notably the Sunrise Equestrian and Recreation Centre for the Disabled.
