The Dominion of Canada has been so much talked about that it may be well to give a summary of its Constitution, though, in so far as regards its relations to the mother country, it differs in no material respect from any other self-governing colony. The Dominion consists of seven provinces, each of which has a Legislature of its own, but is at the same time subject to the Legislature of the Dominion, in the same manner as each State in the American Union has a Legislature of its own, and is at the same time subject to the control of Congress. The distinguishing feature between the system of the American States and the associated colonies of the Dominion of Canada is this--that all Imperial powers, everything that constitutes a people a nation as respects foreigners, are reserved to the mother country. The division, then, of the Dominion and its provinces consists only in a division of Local powers. It is impossible to mark accurately the line between Dominion and Provincial powers, but, speaking generally, Dominion powers relate to such matters--for example, the regulation of trade and commerce, postal service, currency, and so forth--as require to be dealt with on a uniform principle throughout the whole area of a country; while the Provincial powers relate to provincial and municipal institutions, provincial licensing, and other subjects restricted to the limits of the province. As a general rule, the Legislature of the Dominion and the Legislature of each province have respectively exclusive jurisdiction within the limits of the subjects entrusted to them; but, as respects agriculture and immigration, the Dominion Parliament have power to overrule any Act of the provincial Legislatures, and, as respects property and civil rights in Ontario, Nova Scotia, and New Brunswick, the Dominion Parliament may legislate with a view to uniformity, but their legislation is not valid unless it is accepted by the Legislature of each province to which it applies.
