The Rideau Canal, also known as the Rideau Waterway, connects the city of Ottawa, Ontario, Canada on the Ottawa River to the city of Kingston, Ontario on Lake Ontario. The canal was opened in 1832 and is still in use today, with most of its original structures intact. The canal system uses sections of major rivers, including the Rideau and the Cataraqui, as well as some lakes. It is the oldest continuously operated canal system in North America, and in 2007, it was registered as a UNESCO World Heritage Site. The construction of the Rideau Canal was proposed shortly after the War of 1812, when there remained a persistent threat of attack by the United States on the British colony of Upper Canada. In this period, the British built a number of other canals (Grenville, Chute-à-Blondeau and Carillon), as well as a number of forts (Citadel Hill, La Citadelle, and Fort Henry) to impede and deter any future American invasions of Canadian territory.
