Shannon Wiley



Shannon joined Montgomery Sisam in 2011, becoming a Principal in 2021. She is a highly accomplished architect, with a strong design sensibility and extensive technical knowledge that have led to the success of several award-winning projects.

Shannon is a proponent of clear communication and close collaboration within the project team. She works diligently to foster a constructive dialogue between client representatives, stakeholder groups and consultants to develop and deliver the design vision within the constraints of cost and construction. Her managerial acumen and clear, detailed-oriented, hands-on approach to design produces buildings of the highest caliber – sustainable buildings that contribute to a more equitable, inclusive and resilient built environment. And with a strong emphasis on the quality of the human experience, this is work that enhances a sense of place and belonging for all users.

Shannon has helped grow Montgomery Sisam’s experience and expertise in both education and public infrastructure projects. Her notable works include the internationally recognized Myhal Centre for Engineering Innovation and Entrepreneurship, the heritage-designated St. John Henry Newman Secondary School expansion and the newly accessible and community-building West Toronto Railpath Extension. Shannon’s practice is informed by a personal interest in the roles of memory and cultural sensitivity in architecture. She believes understanding and responding to project needs within a historical and culturally specific framework is integral to creating thoughtful, lasting design. Each of these projects demonstrates a careful blend of research, innovation and best-practice that is foundational to Shannon’s approach as an architect, project manager and principal-in-charge.

Shannon has been integral to Montgomery Sisam’s initiative to better support, retain and advance women in our workforce, helping develop and implement several policies and practices to ensure equal opportunity for working mothers. She continues in these efforts, using what she’s learned to champion other equity seeking groups within and outside the office.
