List of tallest buildings in Ottawa–Gatineau


This is a list of the tallest buildings in Ottawa–Gatineau over 90 m tall. Until 1965, buildings in downtown Ottawa were limited to 45.5 metres so that the Peace Tower, part of the parliament buildings, could dominate the skyline. The National Capital Region has a complicated system of protected views that is governed by the National Capital Commission and adhered to by the City of Ottawa. Protected view planes limit the height of buildings in certain areas of the downtown core of Ottawa to ensure clear sight of the Parliament Buildings.
The tallest building in the national capital region is the 45-storey, tall Claridge Icon, which is located in Ottawa's Little Italy.
The tallest development in the national capital region is the 65-storey Trinity Station 1 of the 900 Albert development by Trinity Group. Upon its completion, Tower 1 will be tall and become the tallest building in Ottawa-Gatineau.
