In comparison with either Great Britain or the United States relatively little attention has been given to the problems of public utilities by Canadian economists, business men, and governments. In part, this is due to the outstanding success of some of the publicly owned utilities like Ontario Hydro, Toronto Transportation Commission, and Winnipeg Municipal Electric and, at the same time, to the doubtful value of such public enterprises as the Canadian National. Our experience with these concerns has tended to focus attention on individual cases rather than on public utilities as a group.
Another explanation of the comparative neglect of this field of study is the constitutional framework. In the United States, it has been necessary to prove to conservatively minded courts, first, that the business in question comes within the vaguely defined category of public utilities, and then that the rates set by the regulatory commission have not infringed the Fourteenth Amendment that no person shall be deprived of property without due process of law. Under the British system of government, legislation bringing business under government control and the decisions of commissions regarding rates are, within broad limits, accepted by the courts as valid. Thus the virtually continuous litigation over public utility rates in the United States has been absent in Canada.
Despite this relative neglect, Canadian governments have not by any means entirely disregarded the control of public utilities. The federal government has set up the Board of Transport Commissioners which, since 1904, has supervised the rates, fares, and charges of railways under Dominion jurisdiction. For the most part the Board has dealt with relation of rates inter se. Nevertheless, it has occasionally considered the general level and in the main has accepted the revenue needs of the Canadian Pacific as a basis for rates. In effect it uses the prudent investment of the low cost line for rate-making purposes, but it has not attempted to arrive at either an accurate valuation or a precise figure for a reasonable rate of return. It has almost completely avoided the theoretical and practical difficulties of original cost, cost of reproduction new, and other valuation problems.
