Canada became a self-governing dominion in 1867 while retaining ties to the British crown. Economically and technologically, the nation has developed in parallel with the United States, its neighbour to the south across the world’s longest unfortified border. As a high-tech industrial society in the trillion-dollar class, Canada resembles the United States in its market-oriented economic system, pattern of production, and high living standards. Canada has experienced impressive growth of the manufacturing, mining, and service sectors has transformed the nation from a largely rural economy into one primarily industrial and urban. Canada is the United State’s largest foreign supplier of energy, including oil, gas, uranium, and electric power. Given its abundant natural resources, highly skilled labour force, and modern capital plant, Canada has been enjoying strong economic growth throughout.
