The oldest city in Ontario and the centre of one of North America’s oldest settlements, Sault Ste. Marie has a rich historical heritage due to its Amerindian, British and French influences. Linked to its neighbouring and homonymous American city by a bridge spanning St. Marys River, the city owes its name to the river’s many rapids, called “les saults de Sainte-Marie” by French colonists. The gateway to the Algoma region, renowned for its wild expanses, Sault Ste. Marie is also known as the home of the National Historic Site of the Sault Ste. Marie Canal, which was completed at the end of the 19th century and constitutes the final part of a navigation network that connects the Atlantic Ocean to Lake Superior.
