Ottawa
capital city of Canada
Ottawa ( , ; Canadian French: [ɔtawɑ] ) is the capital city of Canada. It is located in the southeastern portion of the province of Ontario, at the confluence of the Ottawa River and the Rideau River. Ottawa borders Gatineau, Quebec, and forms the core of the Ottawa–Gatineau census metropolitan area (CMA) and the National Capital Region (NCR). As of 2021, Ottawa had a city population of 1,017,449 and a metropolitan population of 1,488,307, making it the fourth-largest city and fourth-largest metropolitan area in Canada.
Ottawa is the political centre of Canada and the headquarters of the federal government. The city houses numerous foreign embassies, key buildings, organizations, and institutions of Canada's government; these include the Parliament of Canada, the Supreme Court, the residence of Canada's viceroy, and the Office of the Prime Minister.
Founded in 1826 as "Bytown", incorporated in 1850, and renamed "Ottawa" in 1855, its original boundaries were expanded through numerous annexations and were ultimately replaced by a new city incorporation and amalgamation in 2001. The municipal government of Ottawa is established and governed by the City of Ottawa Act of the Government of Ontario. It has an elected city council across 24 wards and a mayor elected city-wide, each elected using the first-past-the-post voting election system.
Ottawa has the highest proportion of university-educated residents among Canadian cities and is home to several colleges, universities, and research and cultural institutions, including the University of Ottawa, Carleton University, Algonquin College, Collège La Cité, the National Arts Centre, and the National Gallery of Canada, as well as numerous national museums, monuments, and historic sites.
“Ottawa” enters the record as capital city of Canada. Crown Archives preserves that source wording while asking what Ottawa, capital and city can confirm, complicate or overturn.
Why this record matters
“Ottawa” is worth following because a concise public description often conceals a longer documentary argument. Here, Ottawa, capital and city provides the most credible route into that argument.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Sep 26, 2026. The linked authority identifier is Q1930. VIAF identifies the subject as 130101995. The Library of Congress control number is n79063073. Authority coordinates are 45.425, -75.695. 3 of 5 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 2021, 1826, 1850 and 1855.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
