context_page_description: This is the outline of the geography of the city of Ottawa, the capital of Canada. Ottawa's current borders were formed in 2001, when the former city of Ottawa amalgamated with the ten other municipalities within the former Regional Municipality of Ottawa–Carleton. Ottawa is now a single-tiered census division, home to 870,250 people.
  The city centre is located at the confluence of the Ottawa and Rideau Rivers. The Ottawa River forms the entire northern boundary of the city which it shares with the province] of Quebec's municipalities of Pontiac and Gatineau. The northern boundary begins in the west at Arnprior and continues east to Rockland. The boundary then turns south in a straight line, separating the former Township of Cumberland and the City of Clarence-Rockland. It then turns west in another straight line separating the former Township of Cumberland with the municipalities of The Nation and Russell. It then turns south separating Russell from the former Township of Osgoode. That boundary runs south in a straight line, then turns west separating Osgoode from the municipality of North Dundas.
