Is Lake Ontario the smallest of the Great Lakes?

Lake Ontario is indeed the smallest of the Great Lakes when considering surface area. It has the least amount of surface water compared to the other Great Lakes—Superior, Michigan, Huron, and Erie. This classification is based on standard measurements that show how each lake compares in size.

While other factors such as volume might suggest differing rankings, Lake Ontario consistently holds the title for the smallest in terms of surface area, making this statement true. Seasonality does not alter the fundamental ranking of the lakes based on their sizes.
