Located in the Ottawa Valley in the eastern portion of Southern Ontario, the city lies on the southern banks of the Ottawa River, a major waterway forming the local boundary between the Provinces of Ontario and Quebec. The Rideau Canal, which starts in Kingston, Ontario, winds its way through the city.
The final flight of locks on the canal are between Parliament Hill and the Château Laurier. Also, during the winter season the canal is usually open and is a form of transportation downtown for about 7.8 kilometres for ice skaters and forms the world's largest skating rink.
Ottawa is also home to a wealth of national museums, official residences, government buildings, memorials and heritage structures.
