Ottawa, Ontario, incorporated as a city in 1855, population 934,243 (2016 c), 883,391 (2011 c). The City of Ottawa is the capital of Canada and is located on the Ottawa River on Ontario's eastern boundary with Québec, about 200 km west of Montréal. The name "Ottawa" is thought to derive from an Algonquian-speaking First Nation of the same name, probably from a word meaning "to trade" (see Odawa). Amalgamation, on 1 January 2001, merged "old" Ottawa with 11 area municipalities and the Regional Municipality of Ottawa-Carleton to create a “new” city. The amalgamated city encompasses the municipalities of Ottawa, Vanier, Nepean, Kanata, Gloucester and Cumberland; the townships of Rideau, West Carleton, Goulbourn and Osgoode; and the village of Rockcliffe Park.
