With the advent of responsible government in the 1840s, the power to make civil service appointments was transferred to elected politicians, who had a strong incentive to ensure that French Canadian voters did not feel that they were being frozen out of hiring and promotions. Although no formal reform of the hiring and promotion process was ever undertaken, the patronage-driven hiring process seems to have produced a more equitable representation of the two language groups. In the period between 1867 and the turn of the Twentieth Century, French-Canadians made up about one-third of the Canadian population, and seem also to have represented about one-third of civil service appointments at junior levels, although they had only about half that much representation at the most senior level.
