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 main 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.

Although Canada is officially bilingual (English and French), English is more commonly spoken in Ontario.
