Canada came under the sweep of the Industrial Revolution at one stroke whereas the western movement of the United States was a gradual development. There are no transcontinental railroads controlled by one organization in the United States. In Canada transcontinental roads are distinct entities controlled in eastern Canada. Similarly in financial institutions the branch bank system with its headquarters in the east has been typical of Canada but not of the United States. No such tendency toward unity of structure in institutions and toward centralized control as found in Canada can be observed in the United States.
