Although it does not constitute a separate administrative district, Ottawa is part of the federally designated National Capital Region, which includes the neighbouring Quebec municipality of Gatineau. As with other national capitals, the word "Ottawa" is also used to refer by metonymy to the country's federal government, especially as opposed to provincial or municipal authorities.

History

In the years following the War of 1812, in addition to settling some military regiment families, the government began sponsored immigration schemes which brought over Irish Catholics and Protestants to settle the Ottawa area, which began a steady stream of Irish immigration there in the next few decades. Along with French Canadians who crossed over from Quebec, these two groups provided the bulk of labourers involved in the Rideau Canal project and the booming timber trade, both instrumental in putting Ottawa on the map.

The region's population grew significantly when the canal was completed by Colonel John By in 1832. It was intended to provide a secure route between Montreal and Kingston on Lake Ontario, by-passing the stretch of the St. Lawrence River bordering New York State (the U.S invasions of Canada in the War of 1812 being a recent memory). Construction of the canal began at the northern end, where Colonel By set up a military barracks on what later became Parliament Hill, and laid out a townsite that soon became known as Bytown. Original city leaders of Bytown include a number of Wright's sons,most notably Ruggles Wright. Nicholas Sparks, Braddish Billings and Abraham Dow were the first to settle on the Ontario side of the Ottawa river.

The west side of the canal became known as "Uppertown" where the Parliament buildings are located, while the east side of the canal (wedged between the canal and Rideau River) was known as the "Lowertown". At that time, Lowertown was a crowded, boisterous shanty town, frequently receiving the worst of disease epidemics, such as the Cholera outbreak in 1832, and typhus in 1847.
