Lake Ontario’s name comes from the Iroquoian language and means “lake of shining waters.” The First Nations were the first to live in the watershed, arriving some 7,000 years ago. Today, Lake Ontario is home - and a source of drinking water - to 9-million people living in Ontario, Canada and New York State, USA. Because of the size of the lake and its connection to the Atlantic Ocean, Lake Ontario is an ecological wonder. Fish travel back and forth from the ocean to the freshwater lake. Different parts of the lake offer different habitats, ranging from dunes to wetlands to forest to rocky cliffs. Because of human activities, at least 10 species of fish have gone extinct and at least 15 exotic species have been introduced in the last 200 years.
