Ontario is an eastern-central province bordered by Manitoba and Québec, with a northern coastline on James Bay and Hudson Bay; it also shares the shores of the Great Lakes with the USA. The two most populated areas, around Toronto and Ottawa, are in the southern spur, and the north remains a landscape of forests and lakes. The province contains the Niagara Falls, one of the most spectacular sights in the world.
