The great problem of Canadian federalism is to be found in the sectionalism which is a standing challenge to national unity. Superficial conclusions drawn from the response to national recruitment, war bond drives, and such evidences, which form the stock in trade of the professional patriot, do not stand up against the realities of political behavior. This is revealed at many levels, in the parliaments (provincial and dominion), in federal-provincial relations, and finally at the grass roots as demonstrated at the polls. Geography, history, and economic considerations are woven into this pattern.

Geographically, there are four main regions—Maritimes, St. Lawrence and Great Lakes, Prairies, West Coast. Historically and culturally, the St. Lawrence-Great Lakes region is sub-divided into the former political subdivisions of Lower and Upper Canada, now the provinces of Quebec and Ontario, respectively. In terms of economics, each area presents individual problems, and as contrasting as the wheat-growing prairies and the financial-urban eastern provinces. To the sociologist, there is the complexity of peoples as diverse in background as the French Canadian of Quebec and the Central European immigrant in the West. With these factors in mind, the voting pattern of the people may be discerned, at least in part. And the 1945 general election offers an interesting case study.
