The most important economic activity in Ontario is manufacturing, and the Toronto–Hamilton region is the country's most highly industrialized area. The area from Oshawa, Ontario around the west end of Lake Ontario to Niagara Falls, with Hamilton at its centre, is known as the Golden Horseshoe and had a population of approximately 8.1 million people in 2006. The phrase was first used by Westinghouse President Herbert H. Rogge in a speech to the Hamilton Chamber of Commerce, on January 12, 1954. "Hamilton in 50 years will be the forward cleat in a golden horseshoe of industrial development from Oshawa to the Niagara River ... 150 miles long and wide...It will run from Niagara Falls on the south to about Oshawa on the north and take in numerous cities and towns already there, including Hamilton and Toronto."
