Despite receiving an award by the Ontario Council of University Faculty Associations for outstanding contribution to university teaching,[4] he was nearly terminated in the early 1970s for his radical outspoken views and his obvious contempt for the popular intellectual movements of the late 20th century.
However, with support from Nobel laureate Friedrich von Hayek, after a lengthy struggle, he was given tenure and promoted, rather than being fired.
In economics, two of his most influential lectures were "Keynes and the Death of Gold," and "The Philosophical Origins of Antitrust," which attacked Frank Knight's notion of "pure and perfect competition."
He also regularly gave economics courses at York University, and lectured on Say's law at a conference in the UK in the 1990s.
He and his wife, Virginia Grant Ridpath, had three children, and he lived in Toronto from 1967 until his final year, when he moved to a nursing home in Windsor Ontario.
