Ottawa (/ˈɒtəwə/ ^ⓘ, /ˈɒtəwɑː/; Canadian French: [ɔtawɑ]) is the capital city of Canada. It is located in the southern 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).^[13] 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.^[14][15]

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 Office of the Prime Minister.^[16]

Founded in 1826 as Bytown, and incorporated as Ottawa in 1855,^[17] 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.

Ottawa has the highest proportion of university-educated residents among Canadian cities^[18] and is home to several colleges and universities, research and cultural institutions, including the University of Ottawa, Carleton University, Algonquin College, Collège La Cité, the National Arts Centre, the National Gallery of Canada; and numerous national museums, monuments, and historic sites.^[19] It is one of the most visited cities in Canada, with over 11 million visitors annually contributing more than $2.2B to the city's economy.^[20][21]

The city name Ottawa was chosen in 1855 in reference to the Ottawa River, whose name is itself derived from the Algonquin adawe, meaning "to trade."^[22][23] In modern Algonquin, the city is known as Odàwàg.^[24]

The Ottawa Valley became habitable around 10,000 years ago, following the natural draining of the Champlain Sea.^[25][26] Archaeological findings of arrowheads, tools and pottery indicate that Indigenous populations first settled in the area about 6,500 years ago.^[27][28] These findings suggest that these Algonquin people were engaged in foraging, hunting and fishing, but also trade and travel. Three major rivers meet within Ottawa, making it an important trade and travel area for thousands of years.^[27] The Algonquins are a broad Indigenous people who are closely related to the Odawa and Ojibwe peoples.^[29][30] This period ended with the arrival of settlers and colonization of North America by Europeans during and after the 15th century.^[31]

In 1610, Étienne Brûlé became the first documented European to navigate the Ottawa River, passing what would become Ottawa on his way to the Great Lakes.^[32] Three years later, Samuel de Champlain wrote about the waterfalls in the area and about his encounters with the Algonquin people.^[33]

The first non-Indigenous settlement in the area was created by Philemon Wright, a New Englander. Wright founded a lumber town in the area on 7 March 1800 on the north side of the river, across from the present-day city of Ottawa in Hull.^[34][35] He, with five other families and twenty-five labourers, also created an agricultural community, which was named Wright's Town.^[36][37] Wright pioneered the Ottawa Valley timber trade (soon to be the area's most significant economic activity) by transporting timber by river from the Ottawa Valley to Quebec City.^[38]

In 1826, news of the British military's impending construction of the Rideau Canal led to land speculators founding a community on the south side of the Ottawa River.^[39] The following year, the town was named after British military engineer Colonel John By who was responsible for the entire Rideau Waterway construction project.^[40] The Rideau canal provided a secure route between Montreal and Kingston on Lake Ontario. It bypassed a vulnerable stretch of the St. Lawrence River bordering the state of New York that had left re-supply ships bound for southwestern Ontario easily exposed to enemy fire during the War of 1812.^[41]

Colonel By set up military barracks on the site of today's Parliament Hill. He also laid out the streets of the town and created two distinct neighbourhoods named "Upper Town" west of the canal and "Lower Town" east of the canal. Similar to its Upper Canada and Lower Canada namesakes, historically, "Upper Town" was predominantly English-speaking and Protestant, whereas "Lower Town" was mostly French, Irish and Catholic.^[42]

Bytown's population grew to 1,000 as the Rideau Canal was completed in 1832.^[43][44] Bytown's early pioneer period saw Irish labour unrest during the Shiners' War from 1835 to 1845^[45] and political dissension that was evident in the 1849 Stony Monday Riot.^[46] In 1855, Bytown was renamed Ottawa and incorporated as a city.^[23] William Pittman Lett was installed as the first city clerk, serving from 1844 to 1891, guiding Ottawa through 36 years of development, leading the hiring of key municipal roles, founding civic organizations, and proposing a set of by-laws for the city.^[47][48][49]

The selection of Ottawa as the capital of Canada predates the Confederation of Canada. The choice was contentious and not straightforward, with the parliament of the United Province of Canada holding more than 200 votes over several decades to attempt to settle on a legislative solution to the location of the capital.^[50]

The governor-general of the province had designated Kingston as the capital in 1841. However, the major population centres of Toronto and Montreal, as well as the former capital of Lower Canada, Quebec City, all had legislators dissatisfied with Kingston. Anglophone merchants in Quebec were the leading group supportive of the Kingston arrangement.^[51] In 1842, a vote rejected Kingston as the capital,^[52] and study of potential candidates included the then-named Bytown, but that option proved less popular than Toronto or Montreal.^[53] In 1843, a report of the Executive Council recommended Montreal as the capital as a more fortifiable location and commercial centre; however, the governor-general refused to execute a move without a parliamentary vote.^[54] In 1844, the Queen's acceptance of a parliamentary vote moved the capital to Montreal.^[55]

In 1849, after violence in Montreal, a series of votes was held, with Kingston and Bytown again considered potential capitals. However, the successful proposal was for two cities to share capital status and the legislature to alternate sitting in each: Quebec City and Toronto, in a policy known as perambulation.^[56][57] Logistical difficulties made this an unpopular arrangement,^[58] and although an 1856 vote passed for the lower house of parliament to relocate permanently to Quebec City, the upper house refused to approve funding.^[59]

The funding impasse led to the ending of the legislature's role in determining the seat of government. The legislature requested the Queen determine the seat of government. The Queen then acted on the advice of her governor general Edmund Head,^[60] who, after reviewing proposals from various cities, selected the recently renamed Ottawa. The Queen sent a letter to colonial authorities selecting Ottawa as the capital, effective 31 December 1857. George Brown, briefly a co-premier of the Province of Canada, attempted to reverse this decision but was unsuccessful. The Parliament ratified the Queen's choice in 1859, with Quebec serving as interim capital from 1859 to 1865.^[50][61] The relocation process began in 1865, with the first session of Parliament held in the new buildings in 1866. The buildings were generally well received by legislators.^[62]

Ottawa was chosen as the capital for two primary reasons.^[63] First, Ottawa's isolated location, surrounded by dense forest far from the Canada–US border and situated on a cliff face, would make it more defensible from attack.^[64][65] Second, Ottawa was approximately midway between Toronto and Kingston (in Canada West) and Montreal and Quebec City (in Canada East), making the selection an important political compromise.^[66][67]

Other minor considerations included that despite Ottawa's regional isolation, there was water transportation access from spring to fall, both to Montreal via the Ottawa River, and to Kingston via the Rideau Waterway.^[68] Additionally, by 1854 it also had a modern all-season railway (the Bytown and Prescott Railway) that carried passengers, lumber and supplies the 82 kilometres (50 miles) to Prescott on the Saint Lawrence River and beyond.^[36][64] Ottawa's small size was also thought to be less prone to politically motivated mob violence, as had happened in the previous Canadian capitals.^[69] Finally, the government already owned the land that eventually became Parliament Hill, which it thought would be an ideal location for the Parliament buildings.^[66]

The original Parliament buildings, which included the Centre, East and West Blocks, were constructed between 1859 and 1866 in the Gothic Revival style.^[70] At the time, this was the largest North American construction project ever attempted and Public Works Canada and its architects were not initially well prepared for the relatively shallow-lying bedrock and had to redesign architectural drawings, leading to delays. The Library of Parliament and Parliament Hill landscaping were completed in 1876.^[71]

Starting in the 1850s, entrepreneurs known as lumber barons began to build large sawmills, which became some of the largest mills in the world.^[72] Rail lines built in 1854 connected Ottawa to areas south and, from 1886 to the transcontinental rail network via Hull and Lachute, Quebec.^[73] By 1885 Ottawa was the only city in Canada whose downtown street-lights were powered entirely by electricity.^[74] In 1889, the Government developed and distributed 60 "water leases" (still in use) to mainly local industrialists which gave them permission to generate electricity and operate hydroelectric generators at Chaudière Falls.^[75] Public transportation began in 1870 with a horsecar system,^[76] overtaken in the 1890s by a vast electric streetcar system that operated until 1959.^[77]

The Hull–Ottawa fire of 1900 destroyed two-thirds of Hull, including 40 percent of its residential buildings and most of the buildings of its largest employers along the waterfront.^[78] It began as a chimney fire in Hull on the north side of the river, but due to wind, spread rapidly throughout the widespread wooden buildings. In Ottawa, it destroyed about one-fifth of the buildings from the Lebreton Flats south to Booth Street and down to Dow's Lake.^[79][80] The fire had a disproportionate effect on west-end lower-income neighbourhoods. It had also spread among many lumber yards, a major part of Ottawa's economy. The fire destroyed approximately 3200 buildings and caused an estimated $300 million in damage (in 2020 Canadian dollars).^[81] An estimated 14% of Ottawans were left homeless.^[82]

On 1 June 1912, the Grand Trunk Railway opened both the Château Laurier hotel and its neighbouring downtown Union Station.^[83][84] On 3 February 1916, the Centre Block of the Parliament buildings was destroyed by a fire.^[85] The House of Commons and Senate was temporarily relocated to the recently constructed Victoria Memorial Museum, now the Canadian Museum of Nature^[86] until the completion of the new Centre Block in 1922. The centrepiece of the new Parliament Buildings is a dominant Gothic Revival-styled structure known as the Peace Tower.^[87]

The location of what is now Confederation Square was a former commercial district centrally located in a triangular area downtown surrounded by historically significant heritage buildings, including the Parliament buildings. It was redeveloped as a ceremonial centre in 1938 as part of the City Beautiful Movement. It became the site of the National War Memorial in 1939 and was designated a National Historic Site in 1984.^[88] A new Central Post Office (now the Privy Council of Canada) was constructed in 1939 beside the War Memorial because the original post office building on the proposed Confederation Square grounds had to be demolished.^[89]

Ottawa's former industrial appearance was vastly altered by the 1950 Greber Plan.^[90] Prime Minister Mackenzie King hired French architect-planner Jacques Greber to design an urban plan for managing development in the National Capital Region, to make it more aesthetically pleasing and a location more befitting for Canada's political centre.^[91][92] Greber's plan included the creation of the National Capital Greenbelt, the Kichi Zibi Mikan and the Queensway highway system. His plan also called for changes in institutions such as moving downtown Union Station (now the Senate of Canada Building) to the suburbs, the removal of the street car system, the decentralization of selected government offices, the relocation of industries and removal of substandard housing from the downtown. The plan also recommended the creation of the Rideau Canal and Ottawa River pathways.^[91][93][94]

In 1958, the National Capital Commission was established as a Crown Corporation through the National Capital Act. The commission's original mission was to implement the Greber Plan recommendations conducted during the 1960s and 1970s.^[95] This marked the creation of a permanent political infrastructure for managing the capital region. Prior attempts to do so in the previous 50 years had been temporary. These included plans from the 1899 Ottawa Improvement Commission (OIC), the Todd Plan in 1903, the Holt Report in 1915 and the Federal District Commission (FDC) established in 1927 with a 16-year mandate.^[96][97]

From 1931 to 1958, City Hall had been at the Transportation Building adjacent to Union Station (now part of the Rideau Centre). In 1958, a new City Hall opened on Green Island near Rideau Falls, where urban renewal had recently transformed this industrial location into a green space.^[98] In 2001, Ottawa City Hall returned downtown to a 1990 building on 110 Laurier Avenue West, the home of the now-defunct Regional Municipality of Ottawa-Carleton. This new location was close to Ottawa's first (1849–1877) and second (1877–1931) City Halls.^[99] This new city hall complex also contained an adjacent 19th-century restored heritage building formerly known as the Ottawa Normal School.^[98]

From the 1960s to the 1980s, there was a large increase in construction in the National Capital Region,^[100] which was followed by large growth in the high-tech industry during the 1990s and 2000s.^[101] Ottawa became one of Canada's largest high-tech cities and was nicknamed Silicon Valley North. By the 1980s, Bell Northern Research (later Nortel) employed thousands, and large federally assisted research facilities such as the National Research Council contributed to an eventual technology boom. The early companies led to newer firms such as Newbridge Networks, Mitel and Corel.^[102][103]

In 1991, provincial and federal governments responded to a land claim submitted by the Algonquins of Ontario regarding the unceded status of the land on which Ottawa is situated.^[104] Negotiations have been ongoing, with an eventual goal to sign a treaty that would release Canada from claims for misuse of land under Algonquin title, affirm rights of the Algonquins, and negotiate conditions of the title transfer.^[105]

Ottawa's city limits have expanded over time, including a large expansion effective 1 January 2001, when the province of Ontario amalgamated all the constituent municipalities of the Regional Municipality of Ottawa–Carleton into a single city.^[106] Regional Chair Bob Chiarelli was elected as the new city's first mayor in the 2000 municipal election, defeating Gloucester mayor Claudette Cain.^[107] The city's growth led to strains on the public transit system and road bridges. On 15 October 2001, a diesel-powered light rail transit (LRT) line was introduced on an experimental basis. Known today as the Trillium Line, it was dubbed the O-Train and connected downtown Ottawa to the southern suburbs via Carleton University. The decision to extend the O-Train, and to replace it with an electric light rail system, was a major issue in the 2006 municipal elections, where Chiarelli was defeated by businessman Larry O'Brien.^[108] After O'Brien's election, transit plans were changed to establish a series of light rail stations from the east side of the city into downtown, and for using a tunnel through the downtown core.^[109] Jim Watson, the last mayor of Ottawa before amalgamation, was re-elected in the 2010 election.^[110]

In October 2012, the City Council approved the final Lansdowne Park plan, an agreement with the Ottawa Sports and Entertainment Group that saw a new stadium, increased green space and housing and retail added to the site.^[111][112] In December 2012, City Council voted unanimously to move forward with the Confederation Line, a 12.5 km (7.8 mi) light rail transit line, which was opened on 14 September 2019.^[113]

The present-day city of Ottawa consists of the historic main urban area, as well as other urban, suburban and rural areas within the city's post-amalgamation limits.^[114]

Old Ottawa refers to the former pre-amalgamation city, as well as the former city of Vanier, a densely populated, historically francophone, working class enclave, and the former village of Rockcliffe Park, a wealthy residential neighbourhood adjacent to the Prime Minister's official residence at 24 Sussex and the Governor General's residence.^[115][116] The old city includes the downtown core and older neighbourhoods to the east, west, and south. These vibrant neighbourhoods include the bustling commercial and cultural areas of Old Ottawa South, Centretown, Lower Town, and Sandy Hill, the affluent tree-lined neighbourhoods of The Glebe, Westboro, and New Edinburgh, and the historically blue-collar communities of Hintonburg, Mechanicsville, Carlington, and LeBreton Flats, with a mixture of housing types, artist lofts, and industrial uses. The old city also includes the ethnic enclaves of Chinatown and Little Italy.

Modern Ottawa is made up of eleven historic townships, ten of which are from the former Carleton County and one from the former Russell County.^[117] Ottawa city limits are bounded on the east by the United Counties of Prescott and Russell; by Renfrew County and Lanark County in the west; on the south by the United Counties of Leeds and Grenville and the United Counties of Stormont, Dundas and Glengarry; and on the north by the Regional County Municipality of Les Collines-de-l'Outaouais and the City of Gatineau.^[118][119]

The main suburban areas extend a considerable distance to the east, west and south of the inner-city.^[120][121] These areas also include the former cities of Cumberland, Gloucester, Kanata and Nepean.^[122] The towns of Stittsville and Richmond within the former Goulbourn Township are to the southwest.^[115][123] Nepean as a suburb also includes Barrhaven.^[115][124] The communities of Manotick and Riverside South are on the other side of the Rideau River, and Greely, southeast of Riverside South.^[115]

A number of rural communities (villages and hamlets) are administratively part of the Ottawa municipality.^[120] Some of these communities are Burritts Rapids; Ashton; Fallowfield; Kars; Fitzroy Harbour; Munster; Carp; North Gower; Metcalfe; Constance Bay and Osgoode.^[115] Several towns are within the federally defined National Capital Region but outside the city of Ottawa municipal boundaries;^[120] these include communities of Almonte, Carleton Place, Embrun, Kemptville, Rockland, and Russell.^[115]

Influenced by government structures, much of the city's architecture tends to be formal and functional; the city is also marked by Romantic and Picturesque styles of architecture such as the Parliament Buildings' gothic revival architecture.^[125] Ottawa's domestic architecture contains single-family homes, but also includes smaller numbers of semi-detached houses, rowhouses, and apartment buildings.^[126] Many domestic buildings in Centretown are clad in red brick, with trim in wood, stone, or metal; variations are common, depending on the cultural heritage of the neighbourhoods and the time they were built.^[127]

The skyline has been controlled by building height restrictions originally implemented to keep Parliament Hill and the Peace Tower at 92.2 m (302 ft) visible from most parts of the city.^[128] Today, several buildings are slightly taller than the Peace Tower, with the tallest being the Claridge Icon at 143 metres (469 ft).^[129] Many federal buildings in the National Capital Region are managed by Public Works Canada, which leads to heritage conservation in its renovations and management of buildings, such as the renovation of the Senate Building.^[130][131] Most of the federal land in the region is managed by the National Capital Commission; its control of much undeveloped land and appropriations powers gives the NCC a great deal of influence over the city's development.^{[132][133][134]}

Ottawa has a warm-summer humid continental climate (Köppen: Dfb)^[135] with four distinct seasons and is between Zones 5a and 5b on the Canadian Plant Hardiness Scale.^[136] The average July maximum temperature is 26.7 °C (80 °F). The average January minimum temperature is −14.0 °C (6.8 °F).^[137] The highest temperature ever recorded in Ottawa was 37.8 °C (100 °F) on 4 July 1913, 1 August 1917 and 11 August 1944.^[138][139]

Summers are generally warm and humid in Ottawa. On average, there are 11 days across the three summer months of June, July and August that have temperatures exceeding 30 °C (86 °F). Periods of hotter weather are normally accompanied by high humidity levels^[140]

Snow and ice are dominant during the winter season. On average, almost every day of January, February and March has more than 5 cm of snowpack (29, 28, and 22 days, respectively), and on average, approximately 12 days a year see 5 cm or more of snowfall, with 4 of those having over 10 cm.^[140]

An average of 17 days of the year experience temperatures below −20 °C (−4 °F).^[140] Spring and fall are variable, prone to extreme changes in temperature and conditions. The month of May, for example, on average gets a day below freezing at night every other year, conversely a day surpassing 30 °C ^[140]

Annual rainfall averages around 750mm per year, total precipitation 938mm^[140] spread throughout the year, with some variation. May through November are the months more likely to see significant precipitation events, with each month having an average of 3 days of over 1 cm of precipitation, with December through April seeing on average 1–2 days. May through November have, on average, over 8 cm of rainfall per month, with peaks of approximately 9 cm in June and September. December through April have less than 8 cm, with February being the driest month at an average of 5 cm of precipitation.^[140]

Ottawa experiences about 2,080 hours of average sunshine annually (45% of possible).^[140] Predominate wind direction in Ottawa is from the West, Easterly air flow is more common during periods of wet weather as well as localized river/lake-effect cells on summer afternoons.^[141] Windspeed is on average higher during the winter, with northerly winds predominating during cold waves.^[138][141]

Ottawa is situated on the south bank of the Ottawa River and contains the mouths of the Rideau River and Rideau Canal.^[158] The Rideau Canal (Rideau Waterway) first opened in 1832 and is 202 km (126 mi) long.^[159] It connects the Saint Lawrence River on Lake Ontario at Kingston to the Ottawa River near Parliament Hill. It was able to bypass the unnavigable sections of the Cataraqui and Rideau rivers and various small lakes along the waterway due to flooding techniques and the construction of 47 water transport locks.

Ottawa is situated in a lowland on top of Paleozoic carbonate and shale and is surrounded by more craggy Precambrian igneous and metamorphic formations. Ottawa has had fluvial deposition of till and sands, leading to the widespread formation of eskers. There are limited distinct features arising from glacial deposits, but Ottawa was affected by the Late Wisconsian advance. Before the draining of the Champlain Sea, the area had high salinity. After the draining of the sea, the area had pine-dominated forests.^[160] Ottawa is located within the Western Quebec Seismic Zone, and while relatively inactive, the city does occasionally experience earthquakes.^{[161][162][163][164][165]}

During part of the winter season the Ottawa section of the canal forms the world's largest skating rink, thereby providing both a recreational venue and a 7.8 km (4.8 mi) transportation path to downtown for ice skaters (from Carleton University and Dow's Lake to the Rideau Centre and National Arts Centre).^[166] On 29 June 2007, the Rideau Canal was recognized as a UNESCO World Heritage Site.^[167]

The older part of the city (including what remains of Bytown) is known as Lower Town,^[168] and occupies an area between the canal and the rivers. Across the canal to the west lie both Centretown and Downtown Ottawa, which share a border along Gloucester Street.^[169] These core neighbourhoods contain streets such as Elgin and Bank, which fill the role of commercial main streets in the region.^[170]

Centretown is next to downtown, which includes a substantial economic and architectural government presence across multiple branches of government. The legislature's work takes place in the parliamentary precinct, which includes buildings on Parliament Hill and others downtown, such as the Senate of Canada Building.^[171] Important buildings in the executive branch include the Office of the Prime Minister and Privy Council as well as many civil service buildings.^[172][173] The Supreme Court of Canada building can also be found in this area.^[174]

Across the Ottawa River, which forms the border between Ontario and Quebec, lies the city of Gatineau, itself the result of amalgamation of the former Quebec cities of Hull and Aylmer.^[175] Although formally and administratively separate cities in two different provinces, Ottawa and Gatineau (along with several nearby municipalities) collectively constitute the National Capital Region, which is considered a single metropolitan area.^[176] One federal Crown corporation, the National Capital Commission, or NCC, has significant land holdings in both cities, including sites of historical and touristic importance.^[176] The NCC, through its responsibility for planning and development of these lands, has a crucial role in shaping the development of the city.^[177] Around the main urban area is an extensive greenbelt, administered by the NCC for conservation and leisure, and comprising mostly forest, farmland and marshland.^[178]

In the 2021 Census of Population conducted by Statistics Canada, Ottawa had a population of 1,017,449 living in 407,252 of its 427,113 total private dwellings, a change of 8.9% from its 2016 population of 934,243. With a land area of 2,788.2 km² (1,076.5 sq mi), it had a population density of 364.9/km² (945.1/sq mi) in 2021.^[186]

As of 2021 the Ottawa-Gatineau census metropolitan area (CMA) had a population of 1,488,307 living in 604,721 of its 638,013 total private dwellings, a change of 8.5% from its 2016 population of 1,371,576. With a land area of 8,046.99 km² (3,106.96 sq mi), it had a population density of 185.0/km² (479.0/sq mi) in 2021.^[187]

Ottawa's median age of 40.1 is below the provincial and national averages as of 2016. Youths under 15 constituted 16.7% of the total population in 2016, while those of retirement age (65 years and older) made up 15.4%.^[188]

The 2021 census reported that immigrants (individuals born outside Canada) comprise 259,215 persons or 25.9% of the total population of Ottawa. Of the total immigrant population, the top countries of origin were China (20,320 persons or 7.8%), India (16,200 persons or 6.2%), United Kingdom (14,760 persons or 5.7%), Lebanon (11,900 persons or 4.6%), Philippines (10,505 persons or 4.1%), United States of America (8,795 persons or 3.4%), Haiti (6,710 persons or 2.6%), Syria (6,370 persons or 2.5%), Vietnam (6,155 persons or 2.4%), and Iran (6,000 persons or 2.3%).^[189]

As of 2021, approximately 64.9% of Ottawa's population was white or European, while 2.6% were Indigenous, and 32.5% were visible minorities (higher than the national percentage of 26.5%).^[190]

Ottawa already has the largest rural economy among Canada's major cities.^[221] In Ottawa, the rural economy contributes over $1 billion to the GDP. Agriculture alone accounts for $400 million, $136.7 million of which is farm-gate sales.^[222] Rural economic activity includes agriculture, retail sales, construction, forestry and mining (aggregates), tourism, manufacturing, personal and business services, and transportation, to name a few.

Along with being the capital of Canada, Ottawa is politically diverse in local politics. Most of the city has traditionally supported the Liberal Party in federal elections.^[293][294] The safest areas for the Liberals are the ones dominated by Francophones, especially in Vanier and central Gloucester.^[293] Central Ottawa is usually more left-leaning, and the New Democratic Party have won ridings there.^[295] Some of Ottawa's suburbs are swing areas, such as central Nepean. Another example of a swing area is Orleans, despite its often Liberal Party-aligned francophone population.^[293] Ridings further outside the city centre, such as those including Kanata, Barrhaven and rural areas, tend to be more conservative, fiscally and socially.^[293] This is especially true in the former Townships of West Carleton, Goulbourn, Rideau and Osgoode, which are more in line with the conservative areas in the surrounding counties.^[293] Rural parts of the former township of Cumberland, with a large number of Francophones, traditionally support the Liberal Party, though their support has recently weakened.^[293]

  • Line 1, (Confederation Line) is an east–west line which operates medium-capacity light rail vehicles and travels under the city's downtown core.^[298]
  • Line 2, (Trillium Line), is a north–south rail transit corridor which utilizes a mix of Stadler FLIRTs and Alstom Coradia LINTs connecting the south end of Ottawa to Line 1 at Bayview station.^[299][300]
  • Line 3, is an under construction mass-transit line that will run mostly in parallel to Line 1, splitting at Lincoln Fields station and continuing west.^[301]
  • Line 4, is an under-construction 4 km (2.5 mi) airport link connecting the Trillium Line to the Ottawa Macdonald–Cartier International Airport
• A vast bus rapid transit (BRT) system that uses a series of dedicated bus-only roadways named the Transitway and reserved lanes on city streets and highways. The Transitway has long distances between stops and full station amenities (including platforms, walkways, fare gates, ticket booths, elevators and convenience stores). It connects Ottawa's suburbs to the inner city. The Rapid bus service network operates all day, seven days a week, reaching the suburban communities of Kanata to the West, Barrhaven to the South-West, Orléans to the East, and South Keys to the South.^[302]
• Over 190 local bus routes are served by a fleet of ordinary, articulated and double-decker buses.^[302] Both OC Transpo and the Quebec-based Société de transport de l'Outaouais (STO) operate bus transit services between Ottawa and Gatineau. OC Transpo also operates a door-to-door bus service for disabled individuals known as ParaTranspo.^[297] There is a proposed LRT system that could link Ottawa with Gatineau.^[303]

Intercity bus services are currently provided by several carriers at various stops throughout the city, following the closure of the former Ottawa Central Station bus terminal on 1 June 2021. Major carriers include: Megabus, Ontario Northland, Autobus Gatineau,^{[308][309][310]} and Orléans Express.^[311]

The City of Ottawa has over 12,200 km (7,600 mi) lane-kilometres of road and a series of freeways. The primary freeways are the east–west provincial Highway 417 (designated as the Queensway and part of the Trans-Canada Highway), Ottawa-Carleton Highway 174 (formerly Provincial Highway 17), Highway 7, and the north–south provincial Highway 416 (designated as Veterans' Memorial Highway), which connects to other 400-Series highways via the 401.^[312][313] From downtown there are also freeway connections to Autoroute 5 and Autoroute 50, in neighbouring Gatineau.^[314]

Numerous paved multi-use trails, mostly operated by the National Capital Commission and the city, wind their way through much of the capital, including along the Ottawa River, Rideau River, and Rideau Canal. These pathways are used for transportation, tourism, and recreation. Because many streets either have wide curb lanes or bicycle lanes, cycling is a mode of transportation used by up to 2.5% of citizens, including in winter. This is the largest percentage of any major Canadian city.^{[316][317][318]} As of 31 December 2015, over 900 km (560 mi) of cycling facilities are found in Ottawa, including 435 km (270 mi) of multi-use pathways, 8 km (5.0 mi) of cycle tracks, 200 km (120 mi) of on-road bicycle lanes, and 257 km (160 mi) of paved shoulders.^[319] 204 km (127 mi) of new cycling facilities were added between 2011 and 2014.^[319]

Numerous downtown streets are restricted to pedestrians only. The entire length of Sparks Street was turned into a pedestrian mall in 1966.^[320] Since 1960, additional avenues, streets, and parkways, are reserved for pedestrian and bicycle use only on Saturdays, Sundays and on selected holidays and events.^[321] In 2021 city council unanimously approved the Byward Market Public Realm Plan to make the market area more car-free and pedestrian friendly.^[322] From 2009 to 2015 the NCC introduced the Capital Bixi bicycle-sharing system. This continued until the company VeloGo took over the program from 2015 to 2018 when the partnership ceased.^[323][324] Scooter-sharing systems have since been introduced in the downtown and inner-city areas.^[when?]
