The capital stands on the south bank of the Ottawa River in the eastern portion of southern Ontario. The 2011 census reported a population of 883,391 making it the fourth-largest city in Canada.

It was founded in 1826 and called Bytown. Later in 1855, the name of the city was changed to "Ottawa", the city has evolved into a political and technological centre of Canada. The city name "Ottawa" was chosen in reference to the Ottawa River nearby, which is a word derived from the Algonquin word Odawa, meaning "to trade". By the way, the city is home to a number of post-secondary, research, and cultural institutions, including the National Arts Centre and the National Gallery.
