Erie-Ontario Lowlands

The Erie-Ontario Lowlands are a region in North America, primarily encompassing Southern Ontario, Canada, and parts of New York state in the United States. This area is characterized by gentle relief, with low elevations near Lake Erie and the St. Lawrence River.123

This region is part of the Great Lakes–St. Lawrence lowlands, a physiographic region known for its fertile land, intensive agriculture, industrialization, and high urbanization. The landscape was shaped by glacial activity, resulting in features like glacial lake bottoms and till plains. Major urban centers, including Toronto and Buffalo, are located within this region. The Erie-Ontario Lowlands are bordered by Lake Erie to the south and Lake Ontario to the north.3425
