The National Capital
A long-standing design commitment
DTAH has worked for over 40 years on a series of landscape and urban design projects in Canada’s National Capital, many of which have received national and international design award recognition. Focused largely in the Capital's core, these projects seek to protect the National Symbols and create a coherent, captivating, and livable public realm. Key projects include the Ceremonial Routes urban design plan, and the 15 years of design and construction to realize Confederation Boulevard including Wellington Street; the long-range development plan for the Parliamentary Precinct; “views protection” studies that establish downtown built-form controls required to protect the visual integrity of the Parliament buildings and other National Symbols, and a series of pedestrian and multi-modal bridges over the Rideau Canal, such as the Corktown Footbridge and Laurier Bridge.
Other National Capital projects include the urban design component of the National Capital Core Area Concept Plan, the urban structure plan for the LeBreton Flats area of the Canadian War Museum, and the Capital Core Visual Landscape Assessment Guidelines. Given the significant and overarching impact these projects have had on Ottawa's built and cultural landscape, DTAH's contributions have been documented and referenced in a number of publications, including Ron William's 2014 book Landscape Architecture in Canada and David Gordon's 2015 book Town and Crown.

Our continuous dedication to design excellence in Ottawa has resulted in a cohesive urban fabric that accommodates the needs of an evolving city while conserving the cultural landscape of the Nation’s capital.
More recently, DTAH has guided studies for new commemorations in the National Capital, site rehabilitation strategies for a central sector of the Parliamentary Precinct, and the landscape design and implementation surrounding the Government Conference Centre, temporary home of the Canadian Senate in the historic Ottawa Union Station. We have also completed the Bank of Canada Head Office Renewal, World Exchange Plaza, Vimy Memorial Bridge, and Flora Footbridge.
“The Capital of Canada would not be what it is today without the sophisticated insight and professional counsel that DTAH have provided. ”Linda Dicaire
