Reciprocity, however, was the principal issue everywhere except in Quebec. Powerful forces were arrayed against it. Few manufactures had been put on the free list, but the argument that the reciprocity agreement was the thin edge of the wedge rallied the organized manufacturers in almost unbroken hostile array. The railways, fearful that western traffic would be diverted to United States roads, opposed the agreement vigorously under the leadership of the ex-American chairman of the board of directors of the Canadian Pacific, Sir William Van Horne, who made on this occasion one of his few public entries into politics. The banks, closely involved in the manufacturing and railway interests, threw their weight in the same direction. They were aided by the prevalence of protectionist sentiment in the eastern cities and industrial towns, which were at the same stage of development and in the same mood as the cities of the United States some decades earlier. The Liberal fifteen-year compromise with protection made it difficult in a seven weeks' campaign to revive a desire for freer trade. The prosperity of the country and the cry, "Let well enough alone," told powerfully against the bargain. Yet merely from the point of view of economic advantage, the popular verdict would probably have been in its favor. The United States market no longer loomed so large as it had in the eighties, but its value was undeniable. Farmer, fisherman, and miner stood to gain substantially by the lowering of the bars into the richest market in the world. Every farm paper in Canada and all the important farm organizations supported reciprocity. Its opponents, therefore, did not trust to a direct frontal attack. Their strategy was to divert attention from the economic advantages by raising the cry of political danger. The red herring of annexation was drawn across the trail, and many a farmer followed it to the polling booth. From the outset, then, the opponents of reciprocity concentrated their attacks on its political perils. They denounced the reciprocity agreement as the forerunner of annexation, the deathblow to Canadian nationality and British connection. They prophesied that the trade and intercourse built up between the East and the West of Canada by years of sacrifice and striving would shrivel away, and that each section of the Dominion would become a mere appendage to the adjacent section of the United States. Where the treasure was, there would the heart be also. After some years of reciprocity, the channels of Canadian trade would be so changed that a sudden return to high protection on the part of the United States would disrupt industry and a mere threat of such a change would lead to a movement for complete union.
