Enjoy a cruise on Lake Ontario, the last of the Great Lake before it flows into the St. Lawrence River on its way to the Atlantic Ocean. Visit dynamic cities such as Toronto, Kingston, and Port Weller. The Great Lakes watershed is a region of high biodiversity, and Lake Ontario is important for its diversity of birds, fish, reptiles, amphibians, and plants. Many of these special species are associated with shorelines, particularly sand dunes, lagoons, and wetlands.
