Ontario is one of the thirteen provinces and territories of Canada. Located in Central Canada, it is Canada's most populous province, with 38.3 percent of the country's population, and is the second-largest province by total area (after Quebec). Ontario is Canada's fourth-largest jurisdiction in total area when the territories of the Northwest Territories and Nunavut are included. Ontario is bordered by the province of Manitoba to the west, Hudson Bay and James Bay to the north, and Quebec to the east and northeast, and to the south by the U.S. states of (from west to east) Minnesota, Michigan, Ohio, Pennsylvania, and New York.

Michigan is one of the fifty states in the United States of America. It is the 11th largest state in the United States. It is made up of two peninsulas (connected by the Mackinac Bridge) - the only state to be so. It borders the U.S. states of Wisconsin, Indiana, Ohio, Minnesota, and Illinois. Its borders with Minnesota and Illinois are only by water. It also borders Canada by water. Michigan's total area (including areas of the Great Lakes) is 250,493 km2, while the land area is 150,504 km2. Since the map displayed here only displayes the land area (the water part are omitted), we use the land area number.
