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. To the south, it is bordered by the U.S. states of (from west to east) Minnesota, Michigan, Ohio, Pennsylvania, and New York. Almost all of Ontario's border with the United States follows rivers and lakes: from the westerly Lake of the Woods, eastward along the major rivers and lakes of the Great Lakes/Saint Lawrence River drainage system. There is only about of actual land border, made up of portages including Height of Land Portage on the Minnesota border.
The great majority of Ontario's population and arable land is in Southern Ontario, and while agriculture remains a significant industry, the region's economy depends highly on manufacturing. In contrast, Northern Ontario is sparsely populated with cold winters and heavy forestation, with mining and forestry making up the region's major industries. Provided by Wikipedia
