Alberta Association of Architects
Architectural Institute of British Columbia
Ontario Association of Architects Councillor



After graduating from Carleton University School of Architecture in 1981, David served his internship in architectural firms that focused on housing, shopping centres and heavy industrial projects. The emphasis on design, budget and management from these experiences became the bedrock of his holistic approach to architectural practice.

Since the establishment of David Sin Architect in 1987, he has been credited for a wide range of projects such as social housing, community buildings, heavy industrial complexes, shopping centres and institutional buildings.  His multicultural perspective has taken his practice as far as cities in Southern China and Shanghai.

Although he practices a diverse range of building designs, social/community-oriented projects have always been his cause both personally and professionally. Over the years, he has been instrumental in helping a number of non-profit groups organize and successfully build projects for their communities. In addition to his full involvement in the architectural practice, David has for many years been an active contributor to numerous non-profit organizations in Toronto.  He currently serves as a director on the Board of FCCP Non-Profit Housing Corporation. He is also the Vice President of the Federation of Chinese Canadian Professionals (Ont.) Education Foundation.

Building on a wide portfolio of projects over the past 25 years, he now focuses on the practice of Mission Critical design and the management of project delivery.
