William Christian was a political scientist at the University of Guelph. He retired in 2008. Educated at the University of Toronto (BA, MA) and the London School of Economics (PhD), he is best known academically for his research and teaching in Canadian Political Thought.
Beginning in 1970, he taught at Mount Allison University. He joined the faculty at Guelph in 1978.
In 1974, along with Colin Campbell, he published the first edition of Political Parties and Ideologies in Canada. The scholarship was an original and valuable contribution, since it emphasized the ideological roots shaping Canada and its political parties, as opposed to a social science analysis of power relationships. The textbook distinguished the philosophical foundations of each political party by tracing its comparative tradition, policies, and leaders. In 2006, he and Campbell 'Canadianized' a leading American textbook on ideologies. Besides his academic concerns, he has contributed frequently to the Globe and Mail, the Toronto Star, the Guelph Mercury and the Waterloo Region Record.
