Claude initiated his career in the private sector and then Parks Canada but for the most part worked for the National Capital Commission in Ottawa, where he contributed to many significant projects in a range of portfolios, mainly the official residences, urban parks / open space corridors and Gatineau Park.
In the latter part of his 28-year career with the NCC, he was Chief of the landscape architecture / urban design section and also was given responsibility for the industrial design group. He strived always to reinforce recognition of landscape architecture within the NCC and amongst its collaborators. He retired from the public service in 2015.
With regards to time devoted to the professional association, Claude was a member of the AAPQ Council for 6 years, on the CSLA Board of Directors (2008 - 2014), and CSLA President (2013). He has been involved in many initiatives in service to the CSLA: as judge in various editions of the CSLA Design Awards and the National Urban Design Award, helping to set up and organize annual congresses (Cuba 2007, Mexico 2015), and participating in the accreditation review of the M.L.A. program at the Université de Montréal (2015). One of his key achievements was coordinating a national agreement, ratified in 2015, which clarifies roles and responsibilities of the CSLA and its 9 component associations across Canada.
