The correct answer is C. The Great Lakes region of Canada is dominated by the manufacturing industry.
The Canadian Great Lakes coastline is located entirely in Ontario. 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 of "Manufacturing Heartland of Canada". The province stands out mainly for its strong automotive industry - the most competitive in the entire American continent with the exception of Michigan in the United States. Other important sources of income are tourism and the provision of financial and real estate services.
