The centerpiece of the new flag is the stylized O design, sometimes referred to as a toilet flush. It is meant to be simple, but look festive. When flying, the feeling of vibrant motion is apparent.
The design uses the blue and green colours chosen to represent the new City of Ottawa. The blue is symbolic of rivers and waterways that are part of the Ottawa region. The large green areas speak to the large green space and quality of life in the area.
The flag of Ottawa is highlighted by a stylised O design, sometimes referred to as a 'toilet' flush.
The stylised O is meant to represent both a maple leaf (symbolising Canada) and the Peace Tower and Centre Block of the parliament buildings (symbolising Ottawa).
This flag was adopted by the city in 1901 and when it was replaced it was the oldest municipal flag in Canada.
