As an affluent, high-tech industrial society in the trillion-dollar class, Canada resembles the US in its market-oriented economic system, pattern of production, and affluent living standards. Since World War II, the impressive growth of the manufacturing, mining, and service sectors has transformed the nation from a largely rural economy into one primarily industrial and urban. The 1989 US-Canada Free Trade Agreement (FTA) and the 1994 North American Free Trade Agreement (NAFTA) (which includes Mexico) touched off a dramatic increase in trade and economic integration with the US, its principle trading partner. Canada enjoys a substantial trade surplus with the US, which absorbs nearly 80% of Canadian exports each year. Canada is the US's largest foreign supplier of energy, including oil, gas, uranium, and electric power. Given its great natural resources, skilled labor force, and modern capital plant, Canada has enjoyed solid economic growth, and prudent fiscal management has produced consecutive balanced budgets from 1997 to 2007. In 2008, growth slowed sharply as a result of the global economic downturn, US housing slump, plunging auto sector demand, and a drop in world commodity prices. Public finances, too, are set to deteriorate for the first time in a decade. Tight global credit conditions have further restrained business and housing investment, despite the conservative lending practices and strong capitalization that made Canada's major banks among the most stable in the world.
