Marianne McKenna, OC, FRAIC, OAA, OAQ, AIA, RIBA (born September 25, 1950) is a Canadian architect and a founding partner of KPMB Architects, a Toronto-based practice established in 1987. She is an invested Officer of The Order of Canada "for her contributions as an architect, designing structures that enrich the public realm".
McKenna has led a wide range of projects across the cultural, educational, business, hospitality, and science sectors in Canada and the United States. They include the renovation and expansion of The Royal Conservatory TELUS Centre for Performance and Learning and Koerner Hall (2010 Governor General's Medal), a renovation and expansion of the historic Massey Hall in Toronto, the design of the Kellogg School of Management at Northwestern University, and a vertical campus building for The Brearley School, an independent all-girls school in New York City.
Her current projects include the Dramatics Art Building at Yale University, the Werklund Centre Transformation (formerly Arts Commons) in Calgary, 300 Bloor Street West in Toronto, the redevelopment of St. Monica's Parish in Toronto, and a series of purpose-built rental housing communities with developer Kindred Works in locations across Canada.
McKenna is a recipient of the King Charles III Coronation Medal and the Royal Architectural Institute of Canada's Gold Medal . In 2023, she received an honorary Doctorate of Arts degree from Swarthmore College. She was the first woman to receive a Lifetime Achievement Award from the Design Futures Council.
In 2010, McKenna was named one of CanadaâÂÂs Top 100 Most Powerful Women. She has also been named one of TorontoâÂÂs top 50 Powerful People by MacLeanâÂÂs Magazine, one of the 50 Most Influential Torontonians by Toronto Life, and one of 30 Essential Women in Architecture and Design by Azure Magazine.
McKenna was born in Montreal, Quebec in 1950. She graduated from The Study, a Canadian private education all-girls school in Westmount, Quebec in 1968 and was honoured by The Study in 2008 with the Judy Elder Alumna Award. To the students of The Study, she explained her choice to pursue architecture as follows: "I originally saw the profession as a balance between creative and business skills. I found out quite early that it is much more than that. It is a creative profession but requires the leadership skills of innovator, arbitrator, negotiator, communicator, along with strong design talent and business acumen. The pleasure of architecture is in the range of challenges that only increase from day to day."
McKenna is an alumnus of Swarthmore College (B.A. 1972) and has a Master of Architecture from Yale University (M.A., 1976), where she studied under architects Harry Cobb of Pei Cobb Freed & Partners and Charles Moore. At Yale University, she also met and became lifelong friends with then aspiring actress Meryl Streep. Streep shared insights on MarianneâÂÂs career as an architect in the 2014 documentary "Making Space: 5 Women Changing the Face of Architecture" and in the May 2025 issue of Canadian Architect magazine.
Upon graduation from Yale, McKenna worked for Bobrow & Fieldman, Architects in Montreal from 1976 to 1978 and Denys, Lasdun, Redhouse & Softely in London from 1978 to 1979. In 1980 she joined Barton Myers Associates (BMA) in Toronto and was made an associate the following year. At BMA she met her future partners, also associates of Myers: Bruce Kuwabara, Thomas Payne and Shirley Blumberg. Notable projects she worked on in this period include the Hasbro Inc. New York showrooms and 35 East Wacker Drive in Chicago.
When Barton Myers relocated his office to Los Angeles in 1987, McKenna formed Kuwabara Payne McKenna Blumberg Architects (KPMB Architects) with Bruce Kuwabara, Thomas Payne and Shirley Blumberg. Early in the practice, the editorial director of Progressive Architecture, Thomas R. Fisher, wrote: "...KPMB is particularly noteworthy because it has developed a more open, hybrid form of architecture and has taken the much more unusual step of structuring its practice along the same lines. The partnership, for example, is a mix of people of different genders, religious beliefs, ethnic backgrounds and political inclinations...theirs, in other words, is neither the autonomous individualism of the âÂÂstarâ design firm nor the rather anonymous specialization of corporate-type firms, but a more diverse and less structured hybridization of those older models."
With her partners, McKenna developed an approach where each of the four partners is either in charge of their respective projects or collaborates strategically to combine strengths in leadership and design on large-scale, complex initiatives, leading teams through all phases from design concept to delivery. Simultaneous to the project work, the partnership shares responsibility for directing the strategy and management of all four core areas of practice: business development, design, finance, marketing and administration. In 2012, the name of the partnership changed to KPMB Architects. KPMB Architects is today recognized as a leading Canadian practice.
The architecture of concert halls is one of McKennaâÂÂs areas of focus. McKenna is responsible for the transformation and expansion of The Royal Conservatory into a Toronto cultural destination. Her work began with the 1990 Master Plan, continued for over a decade with phased and various projects including Ettore Mazzoleni Concert Hall and culminated with the TELUS Performance and Learning Centre (2008) and Koerner Hall (2009), which has been referred to by media as the âÂÂjewel in the crown of TorontoâÂÂs cultural renaissanceâÂÂ. The design achieved numerous awards, including the Governor GeneralâÂÂs Medal in 2012. For her outstanding contribution and commitment, Marianne was made an Honorary Fellow of the Royal Conservatory in 2011.
Reflecting on her work at the Conservatory, McKenna says, "The wonderful part of this project is the opportunity to overlay so many aspects of music, from the teaching and practicing of the students, to the performance of faculty and musicians from across the city and around the world. The buildings, both the historic stone fabric and the more contemporary fabric stretched across the site, become a crucible for amazing musical variations."
McKenna also led the renewal of Orchestra Hall in Minneapolis (2017 Architectural Record, âÂÂGood Design is Good Business AwardâÂÂ), the expansion of the Jenny Belzberg Theatre at the Banff Centre for Arts and Creativity in Banff, Alberta, and the multi-phase renovation and expansion of the iconic Massey Hall and Allied Music Centre in Toronto.
McKennaâÂÂs educational projects for science, engineering, business, and liberal arts programs include the Kellogg School of Management at Northwestern University, the Rotman School of Management at the University of Toronto (2014 Governor GeneralâÂÂs Medal, Architectural Record "Good Design is Good Business Award"), the Mike and Ophelia Lazaridis Quantum-Nano Centre at the University of Waterloo, the McGill University and Génome Québec Innovation Centre in Montreal, and Le Quartier Concordia, an integrated vertical campus for Concordia University in downtown Montreal.
As partner-in-charge, McKenna has directed many of KPMBâÂÂs projects including the Rotman School of Management at the University of Toronto (2014 Governor GeneralâÂÂs Award and Architectural Record "Good Design is Good Business Award"); the Jackson-Triggs Niagara Estate Winery in Niagara-on-the-Lake (CanadaâÂÂs selection at the 2002 Green Building Challenge in Oslo, Norway); the Master Plan for Ryerson University (2010 American Institute of Architects Honor Award); the Grand Valley Institution for Women (1997 Governor's General Medal); the restoration and expansion of Park Hyatt Toronto; an office and event space for The Globe and Mail; and offices for Torys LLP, Woodbridge Co. Ltd., and Gluskin Sheff .
McKenna also developed and implemented the professional practice course at the University of TorontoâÂÂs John H. Daniels Faculty of Architecture, Landscape and Design. In the fall of 2016, she was the Lord Norman R. Foster Visiting Professor at Yale University. She previously served on the Advisory Board for the McEwen School of Architecture at Laurentian University, which awarded McKenna an Honorary Doctorate of Laws (honoris causa) degree in June 2017. In 2025, she served on the design jury for the Holcim Foundation Awards.
