Born in Québec City in 1929, Claude Castonguay is an educator, politician and businessman. Attendance at Laval University from 1948 to 1950, followed by the study of actuarial science at the University of Manitoba from 1950 to 1951, qualified Castonguay to lecture at Laval University from 1951 to 1957 while he worked as an actuary at several Quebec insurance companies.
