Patrick Simmons joined the firm, then known as Rieder, Hymmen & Lobban Architects, in 1992, becoming a partner in 1994. Patrick’s work has been guided by an ethic shaped by his diverse experiences, including eight years competing with Canada’s National Water Polo Team, practicing architecture with Griffiths Rankin Cook Architects in Ottawa, and earning a Master of Architecture in Urban Design from Harvard University. After 33 years with the firm, Patrick retired in March 2025.
“When someone walks into a building, it should be very clear how they’re supposed to live, work, or visit within it. That comes from working through the details over and over again and revealing those details honestly, so people can understand how the building is constructed and how it works. That’s how you create a sense of transparency and authenticity that reveals the essence of the architecture.”
Some of Patrick’s most notable projects that have defined the architectural identity of the Kitchener-Waterloo Region include Economical Insurance, A Grander View, OpenText, BlackBerry Northfield Campus, 560 Westmount, and Blacksmith Lofts. Most recently, Patrick helped lead the highly successful Gaslight District and Tapestry Hall, along with the soon-to-be iconic Cambridge Mill Hotel and Residences. These accomplishments, among many others, have set a standard of excellence that has defined our firm’s growth and success over the last 30+ years.
“The process of design really intrigued me. You start with a sketch, then you revise it, talk to people, and work until it makes sense and works well. Thinking that you can draw things that will actually get built was very exciting.”
Residing in Cambridge, Ontario, Patrick has made a lasting mark on the region both architecturally and socially. His involvement with the School of Architecture at the University of Waterloo, the Cambridge Memorial Hospital's Capital Projects Sub-Committee, and the Cambridge BIA reflects his passion for service and for nurturing the next generation of architects. The MSS team is looking forward to watching how he will continue to use his talents for the good of our region.
“There’s a reason I have maintained a 25 year relationship with Patrick and his team. Whether it's redeveloping historic properties, residential development, or office campuses, MartinSimmons can meet aggressive deadlines, oversee the contractor and subconsultants, and provide a product we’re proud of.”
Notable Projects
“Since this [560 Westmount] project was a speculative space without a tenant, we were almost given carte blanche to imagine how the project could look and function. We came up with a very sculptural design that could accommodate a variety of functions and fit the challenging site, which was long and very narrow. We used great materials and form to create the impression that this is a building and organization of international importance. Inside, the overall concept was an Italian piazza. As you’re sitting in the atrium cafe, you can catch glimpses of the conservation area out one side of the building, the city on the other, and meeting rooms, labs, or offices around you the way you would in an old Italian town.”
