The main source of income for Ontario is the industry. The value of industrial products produced in Ontario is greater than the sum of the total value of industrial products manufactured in all other provinces and territories of Canada. The strength of its manufacturing industry earned it the nickname Manufacturing Heartland of Canada. The province stands out mainly for its strong automotive industry the most competitive of the entire American continent with the exception of Michigan of the United States. Other important sources of income are tourism and the provision of financial and real estate services.
Ontario is one of the richest and most economically prosperous national subdivisions of North America, thanks to its strong and varied economy, its gradually growing population and the existence of skilled labour.
