Flag of Ottawa

The flag of Ottawa is blue on the left and green on the right with a stylized white "O" design in the middle. It was adopted following the amalgamation of municipalities in the Regional Municipality of Ottawa–Carleton into Ottawa in 2001. The blue symbolizes the waterways of the region, and the green represents its green spaces. The "O" represents "the vibrancy and forward movement of the new City." The meeting of the bands at a common point symbolizes unity towards a common goal. The shape of the bands of the "O" abstractly hints at the maple leaf, which is a national symbol of Canada, and the Canadian Parliament Buildings, which are located in Ottawa.
