Quinn Design Associates
Landscape Architects


Quinn Design Associates Inc. was established in Toronto, Ontario in 1987 by John Quinn, a landscape architect with a background in horticulture and a passion for urban design. Thirty years later, John continues to develop and nurture the firm.

Located for the past decade in Toronto’s Yorkville neighbourhood, Quinn Design Associates is a collaborative design firm with dedicated staff trained in landscape architecture, urban design, architecture, and technology. John and Greg work with our talented team to offer clients expertise in the design of urban and public spaces.

Our portfolio of work, located throughout Ontario and internationally, includes a range of project types: from University and civic buildings to hospitals, retail centres, and multi-unit residential projects. Notable recent work includes the Humber River Hospital, Quinte Consolidated Courthouse, and the Humber College Learning Resource Commons. Among our current projects are: Rodeo Drive Condominium in Don Mills, the 160 Front Street West office tower, Peel Memorial Centre, and Seneca College's Centre for Innovation, Technology, and Entrepreneurship.


Quinn Design Associates is committed to design excellence on every project. Our firm strives to address and balance complex design, social, and environmental issues through an innovative yet pragmatic approach. We approach each project with an interest in addressing the architecture of the site and the larger urban context to create a contemporary and dynamic design. We are enthusiastic collaborators within our firm, with the project team, and with our clients. We pride ourselves on providing our clients with rigorous and responsive services that respect schedules and budgets.

Our diverse portfolio of successfully built projects for both private and public clients in Canada and internationally demonstrates our dedication to sound design principles and seeing projects through to completion. We are as committed to ensuring that our clients achieve their objectives as we are to environmental sustainability, and to creating places that delight and inspire.
