Ottawa is the capital city of Canada. It is in the southern part of Ontario, where the Ottawa River and Rideau River meet. Ottawa is right next to Gatineau, Quebec, and together they form the heart of the National Capital Region.
As of 2021, Ottawa had a population of over 1 million people. This makes it the fourth-largest city in Canada. When you include the nearby metropolitan area, the population is almost 1.5 million.
Ottawa is Canada's political hub. It is home to the main offices of the federal government. You can find many foreign embassies here. Important government buildings like the Parliament of Canada and the Supreme Court are also in Ottawa. The official residence of Canada's viceroy, Rideau Hall, is also located here.
The city was first started in 1826 as Bytown. It officially became the City of Ottawa in 1855. Its borders have grown over time. In 2001, many smaller towns nearby joined to form the larger City of Ottawa we know today. The city's government is run by an elected city council and a mayor.
Ottawa has many people who have gone to university. It is home to several colleges and universities. These include the University of Ottawa and Carleton University. The city also has many museums, monuments, and historic sites. Over 11 million people visit Ottawa every year, making it one of Canada's most popular cities for tourists.

What Does Ottawa Mean?
The name Ottawa was chosen in 1855. It comes from the Ottawa River. The river's name comes from the Algonquin word adawe. This word means "to trade." In modern Algonquin, the city is called Odàwàg.
Ottawa's Story
Early Times

The Ottawa Valley became a good place to live about 10,000 years ago. This was after the Champlain Sea naturally drained away. Scientists have found old arrowheads, tools, and pottery here. These show that Indigenous people first lived in the area about 6,500 years ago. They hunted, fished, gathered food, and traded.
Three big rivers meet in Ottawa. This made it an important place for trade and travel for thousands of years. The Algonquin people are a large Indigenous group. They are related to the Odawa and Ojibwe peoples. This early period ended when European settlers arrived in North America.
European Explorers and Early Growth
In 1610, Étienne Brûlé was the first European to travel on the Ottawa River. He passed by the area that would become Ottawa. Three years later, Samuel de Champlain wrote about the waterfalls and meeting the Algonquin people.
The first non-Indigenous settlement was started by Philemon Wright. He was from New England. On March 7, 1800, Wright started a lumber town. It was on the north side of the river, where Hull is today. He also started a farming community called Wright's Town. Wright was a pioneer in the Ottawa River timber trade. This trade became very important. He transported timber down the Ottawa River to Quebec City.
In 1826, the British military planned to build the Rideau Canal. This news led people to buy land and start a community on the south side of the Ottawa River. The next year, the town was named Bytown. It was named after Colonel John By. He was a British military engineer in charge of building the Rideau Waterway.

The Rideau Canal created a safe route between Montreal and Kingston. This route avoided a dangerous part of the St. Lawrence River. That area was close to New York and could be attacked during the War of 1812.
Colonel By built military barracks where Parliament Hill is now. He also planned the streets of the town. He created two different areas: "Upper Town" west of the canal and "Lower Town" east of the canal. "Upper Town" was mostly English-speaking and Protestant. "Lower Town" was mostly French, Irish, and Catholic.
Bytown's population grew to 1,000 people by 1832, when the Rideau Canal was finished. In 1855, Bytown was renamed Ottawa and became a city. William Pittman Lett was the first city clerk. He helped guide Ottawa's growth for 36 years.
Why Ottawa Became the Capital
Choosing Ottawa as Canada's capital was a big deal. It happened before Canada became a country. The parliament of the Province of Canada voted over 200 times to decide where the capital should be.
In 1841, Kingston was chosen as the capital. But people from bigger cities like Toronto, Montreal, and Quebec City were not happy. In 1842, a vote rejected Kingston. Bytown was considered, but it was not as popular as Toronto or Montreal. In 1844, the capital moved to Montreal.
In 1849, after some violence in Montreal, more votes were held. Kingston and Bytown were again considered. The idea of two cities sharing the capital role was tried. Quebec City and Toronto would take turns hosting the legislature. But this was difficult to manage.
Finally, the Queen was asked to decide. Queen Victoria listened to her governor general, Edmund Walker Head. He looked at proposals from different cities. He chose Ottawa. The Queen sent a letter choosing Ottawa as the capital, effective December 31, 1857. Parliament agreed with her choice in 1859. The move started in 1865, and the first Parliament session in the new buildings was in 1866.

Ottawa was chosen for two main reasons. First, it was in an isolated location. It was surrounded by thick forests and on a cliff. This made it easier to defend from attacks. Second, Ottawa was about halfway between Toronto and Kingston (in Canada West) and Montreal and Quebec City (in Canada East). This made it a good compromise for everyone.
Other reasons included its water transportation access. It could reach Montreal by the Ottawa River and Kingston by the Rideau Waterway. By 1854, it also had a modern railway. This railway connected Ottawa to Prescott on the Saint Lawrence River. Ottawa's small size was also seen as a good thing. It was thought to be less likely to have political violence, which had happened in previous capitals. Also, the government already owned the land that became Parliament Hill. They thought it was a perfect spot for the Parliament buildings.
The first Parliament buildings were built between 1859 and 1866. They were designed in the Gothic Revival style. This was the biggest construction project in North America at the time. The Library of Parliament and the landscaping on Parliament Hill were finished in 1876.
After Canada Became a Country

In the 1850s, business owners called "lumber barons" built huge sawmills. These became some of the biggest mills in the world. Rail lines built in 1854 connected Ottawa to other areas. By 1885, Ottawa was the only city in Canada with downtown streetlights powered entirely by electricity. Public transportation started in 1870 with horse-drawn streetcars. These were replaced by electric streetcars in the 1890s.
The 1900 Hull–Ottawa fire destroyed two-thirds of Hull. It also destroyed about one-fifth of Ottawa's buildings. The fire started in Hull and spread quickly because of the wind. It caused about $300 million in damage (in today's money). About 14% of Ottawa's people lost their homes.
On June 1, 1912, the Château Laurier hotel and the downtown Union Station opened. On February 3, 1916, the Centre Block of the Parliament buildings was destroyed by a fire. Parliament moved to the Victoria Memorial Museum (now the Canadian Museum of Nature) until the new Centre Block was finished in 1922. The new Parliament Buildings feature the tall Peace Tower.
The area that is now Confederation Square was redeveloped in 1938. It became a ceremonial center. The National War Memorial was placed there in 1939.
After World War II


Ottawa's look changed a lot after the 1950 Greber Plan. Prime Minister Mackenzie King hired a French architect, Jacques Greber. He designed a plan to make the National Capital Region more beautiful. Greber's plan included creating the National Capital Greenbelt. It also suggested moving some government offices and removing old buildings downtown.
In 1958, the National Capital Commission (NCC) was created. Its job was to carry out the Greber Plan. The NCC helps manage the capital region.
From the 1960s to the 1980s, a lot of construction happened. Then, in the 1990s and 2000s, the high-tech industry grew a lot. Ottawa became one of Canada's biggest high-tech cities. It was even called "Silicon Valley North." Many big tech companies like Nortel, Corel, and Shopify started here.
In 1991, the governments started talking with the Algonquins of Ontario. This was about their land claim for the land Ottawa is on. These talks are still happening.
Ottawa's city limits have grown over time. On January 1, 2001, many nearby towns joined to form one big city. Bob Chiarelli became the new city's first mayor. The city's growth led to changes in public transportation. In 2001, a diesel-powered light rail transit (LRT) line was started. It was called the O-Train. It connected downtown Ottawa to the southern suburbs. Later, plans were made to expand the O-Train and make it electric.
In 2012, the City Council approved the Lansdowne Park plan. This plan included a new stadium and more green space. In December 2012, the City Council voted to build the Confederation Line. This is a 12.5 km (7.8 mi) light rail line. It opened on September 14, 2019.
Where is Ottawa?
Neighborhoods
Today, Ottawa includes the old main city area. It also has other urban, suburban, and rural areas that joined the city later.
Old Ottawa
"Old Ottawa" refers to the city before it expanded. It includes the former city of Vanier. This area is densely populated and has many French-speaking residents. It also includes Rockcliffe Park, a wealthy neighborhood. The old city has the downtown core and older neighborhoods to the east, west, and south. These areas include busy places like Old Ottawa South and Centretown. There are also tree-lined neighborhoods like The Glebe and New Edinburgh.
Suburbs and Nearby Communities
Modern Ottawa is made up of eleven historic townships. Ten are from Carleton County and one from Russell County. Ottawa's borders are next to other counties in Ontario and Quebec.
The main suburban areas stretch far to the east, west, and south of the city center. These areas include the former cities of Cumberland, Gloucester, Kanata, and Nepean. The towns of Stittsville and Richmond are to the southwest. Barrhaven is also a suburb.
Many rural communities are part of the Ottawa municipality. These include villages and hamlets like Burritts Rapids and Carp. Some towns are in the National Capital Region but outside Ottawa's city limits. These include Almonte and Rockland.
Buildings and Design

Many of Ottawa's buildings are formal and practical. This is because of the many government buildings. But you can also see romantic and picturesque styles, like the Gothic Revival architecture of the Parliament Buildings. Ottawa has single-family homes, semi-detached houses, and apartment buildings. Many older homes in Centretown are made of red brick.
The city has rules about building height. These rules were made to keep Parliament Hill and the Peace Tower visible. The Peace Tower is 92.2 meters (302 feet) tall. Today, some buildings are slightly taller. The tallest is the Claridge Icon at 143 meters (469 feet).
The National Capital Commission (NCC) manages most federal land in the region. The NCC has a lot of power over how the city develops. This is because it controls much undeveloped land.
Weather in Ottawa
Ottawa has four distinct seasons. Summers are usually warm and humid. On average, there are 11 days in June, July, and August where temperatures go above 30°C (86°F). Hot weather often comes with high humidity.
Snow and ice are common in winter. Almost every day in January, February, and March has more than 5 cm (2 inches) of snow on the ground. About 12 days a year see 5 cm (2 inches) or more of snowfall. About 17 days a year have temperatures below -20°C (-4°F).
Spring and fall weather can change a lot. For example, in May, it might freeze at night every other year. But it can also reach over 30°C (86°F) during the day.
Ottawa gets about 750 mm (30 inches) of rain each year. Total precipitation is about 938 mm (37 inches). May through November are the wettest months. February is the driest month.
Ottawa gets about 2,080 hours of sunshine each year. This is about 45% of the possible sunshine. Winds usually come from the west. Winter winds are stronger, often coming from the north during cold spells.

Physical Features
Ottawa is on the south bank of the Ottawa River. The Rideau River and Rideau Canal also flow into it here. The Rideau Canal opened in 1832. It is 202 km (126 mi) long. It connects the Saint Lawrence River to the Ottawa River. The canal has 47 water transport locks.
Ottawa is in a low-lying area. It sits on top of old rock layers. The city has been shaped by glaciers and ancient seas. Ottawa is in an area where earthquakes sometimes happen, but it is usually quiet.
City Design
In winter, the Ottawa section of the canal becomes the world's largest skating rink. It is 7.8 km (4.8 mi) long. People use it for fun and to travel downtown. In 2007, the Rideau Canal became a UNESCO World Heritage Site.
The older part of the city is called Lower Town. It is between the canal and the rivers. Across the canal to the west are Centretown and Downtown Ottawa. These areas have busy streets like Elgin and Bank.
Centretown is next to downtown. It has many government buildings. The legislature works in buildings on Parliament Hill and downtown. Important buildings for the executive branch are also here. The Supreme Court of Canada building is in this area too.
Across the Ottawa River is Gatineau. Ottawa and Gatineau are separate cities in different provinces. But they form the National Capital Region. This is seen as one big metropolitan area. The National Capital Commission (NCC) owns a lot of land in both cities. The NCC helps plan how the city develops. Around the main urban area is a large greenbelt. The NCC manages it for nature and recreation.
