The expansion of the Niagara Peninsula has occurred with its advance from a frontier of conflict to one of contact. Lying at the western extremity of the Hudson-Mohawk, that “greatest of all routes of continental migration,” it forms a major land bridge from New York to Ontario, and exerts the same attraction today, when it has become one of the chief international regions linking Canada with the United States, as it did in the mid-nineteenth century, when it formed part of the great overland route drawing immigrants to the West, or even earlier, when it was itself a pioneer zone. At the same time it is a prime water link between west and east, and, being used both by American and Canadian, has helped to bring them together, first in the commercialization of the St. Lawrence, and later in its industrialization. As a result it is one of the few districts of Canada able to show a continued native growth, together with a “pull on the northern margins of the neighbouring states at all comparable to that of the numerous urban and industrial regions of the United States.”
Thanks to these advantages, its population has increased fifteen times in the last 120 years, with an expansion in recent decades only exceeded by that of the early pioneer influx (see Figure 1). Its problems, therefore, are associated with growth, and with the attempts to work out a series of integrations with each new stage of development, in order to preserve equilibrium in expansion, and create new organizations of settlement and society. Its chequered history, especially as represented in the urban centre, has shown the varying success with which these issues have been met.
