  The Great Lakes also have several peninsulas between them, including the Door Peninsula, the Peninsulas of Michigan, and the Ontario Peninsula. Some of these peninsulas even contain smaller peninsulas, such as the Bruce, Keweenaw, Leelanau, Niagara, and Thumb peninsulas. Population centers on the peninsulas include Grand Rapids, Flint, and Detroit in Michigan along with London, Hamilton, Brantford, and Toronto in Ontario.
