William Charles Winegard, PC OC (September 17, 1924 – January 31, 2019) was a Canadian educator, engineer, scientist and member of Parliament.
In 1952, William received his doctorate in metallurgical engineering from the University of Toronto and he taught there until 1967.
He and several other community activists, formed a group they call the Old Man's Club, and they want the site of the former Guelph Correctional Centre to remain green and are opposed to development on that land.
He was also against the Ontario Liberal Government's decision to close the Guelph Pacemaker Clinic, forcing about 2,000 Guelphites, mainly seniors, to go to Kitchener for treatment.
On November 11, 2014, he spoke at the Remembrance Day service in Guelph, in which he criticized the Harper Government for its handling of Canadian Veterans.
