Leslie Parker


Senior Associate

Leslie joined Montgomery Sisam in 2005 and was appointed to the position of Senior Associate in 2016. With particular expertise in designing long term care, healthcare, seniors’ housing and institutional facilities, Leslie has assumed a leadership role as both Project Architect and Contract Administrator on many of the firm’s care-sector projects.

In her role as Project Architect, Leslie has managed a large and complex addition and renovation at St. Thomas Elgin General Hospital, procured through a build-finance model.  She has been the Project Architect for all of our work with Extendicare Canada since 2010 with projects including Extendicare Sault Ste Marie, Timmins, Kingston and Sudbury among others. Leslie’s broad portfolio includes a series of interior renovations for the Medcan Clinic in Toronto, the Prominence Way Retirement Community in Calgary and the multi-phased renovation of John Noble Home. Leslie is committed, in her work, to ensuring homes have a strong residential character while meeting all the demands of an institutional setting.

Leslie has also collaborated on a number of highly sustainable projects including the Restoration Services Centre for Toronto and Region Conservation Authority, the first LEED Platinum certified project in Eastern Canada.

Offering expedient, practical and cost-effective solutions, she has an exceptionally responsive approach to project management allowing her to work successfully within rigid schedule and budget constraints.
