Without pressure from a small but influential group of London financiers, Confederation would not have occurred in 1867, if at all. These financiers supported the unification of the British North American colonies because they believed it would rescue their under-performing investments and keep British North America within the British Empire. Andrew Smith discusses the role of British investors in Canadian Confederation, covering the period from the construction of the Grand Trunk Railroad in the 1850s to Canada's purchase of Rupert's Land in 1869-70.He describes how some investors lobbied the British government for the policies that made Confederation possible, working closely with the Fathers of Confederation, many of whom were participants in the same trans-Atlantic crony-capitalist system. British factory owners with classical liberal beliefs, however, disliked Confederation because they believed it would delay the political independence of the North American colonies, something they saw as beneficial. "British Businessmen and Canadian Confederation" reminds Canadians that most contemporaries of Confederation saw it as a way to preserve the colonists' bonds with Britain rather than to expand their political autonomy. It should interest a wide audience - from students of Canadian political history to historians interested in Victorian globalization.
