The northern end of the Appalachian Basin extends offshore into Lakes Erie and Ontario as far as the United States–Canada border. The province covers an area of about 185,500 square miles (480,000 km 2 ) and is 1,075 miles (1,730 km) long from northeast to southwest and between 20 and 310 miles (30 and 500 km) wide from northwest to southeast.
