4. Kingston

Located where Lake Ontario meets the St. Lawrence River, Kingston is a historic city known as the "Limestone City" because of its many heritage buildings made from local limestone.

The Importance of Lake Ontario to These Cities

Lake Ontario acts as a crucial economic and cultural lifeline. Historically, it enabled trade and transport, connecting the Great Lakes to the Atlantic Ocean via the St. Lawrence River. Today, it still supports commercial shipping through the St. Lawrence Seaway and provides vital drinking water to millions.

The lake also enhances the quality of life for residents and attracts tourists with its beaches, parks, boating, and fishing opportunities. Additionally, the cities along Lake Ontario are at the forefront of efforts to protect its waters, balancing development with environmental stewardship.
