Victoria Hayward described the cultural changes of the
Canadian Prairies as a "mosaic" as early as the 1920s: Another early use of the term
mosaic to refer to Canadian society was by
John Murray Gibbon, in his 1938 book
Canadian Mosaic. Gibbon clearly disapproved of the American melting-pot concept. He saw the melting pot as a process by which
immigrants and their descendants were encouraged to cut off ties with their countries and cultures of origin so as to assimilate into the American way of life. In 1965,
John Porter published his influential sociological study,
The Vertical Mosaic: An Analysis of Social Class and Power in Canada. The study examined equality of opportunity and the exercise of power by bureaucratic, economic, and political elites in Canada, with Porter arguing that "not unlike other western industrial nations", Canada relied "on its elite groups to make major decisions and to determine the shape and direction of its development." In their work, Porter also argues that certain ethnic groups tended to fare better than others in regards to measures of income, education, and health than others, and as such classified them as "elite groups", who tended to be overrepresented among Canada's
elites in
government,
economic and
political spheres. Porter’s findings have been tested in several studies since 1965 and have been modified slightly. For example, the economic disparity between ethnic groups has narrowed somewhat and
Francophones are better represented in politics and government. However, the
socio-economic elites in Canada remain dominated by people of British origin. ==Influence on multiculturalism policy==
