About Us

Empowering Architecture

We are Architects. We bring our experience, design skills and technical expertise to create spaces that delight and transform learning, living, working, care and hospitality facilities. Our carefully crafted, signature environments support the needs of individuals and transform their lives. We create inspired, iconic architectural visions by clearly identifying our clients’ needs and aspirations, as well as their cultural and market values. At Kearns Mancini, passion motivates our work. We seek out and drive the innate transformative qualities of architecture in a way that will inspire and empower our clients and their communities.


We are driven to truly understand and define the soul of a project, and never rest until we have found the ideal solution - one that allows the end-users of our buildings to naturally become a part of their new space while being liberated by it. Our principles promote the transformation of the human environment in a thoughtful way and we believe the key to that success is based on these key qualities:

We empower and enable you throughout our design process. It's how we intimately extract the true essence and needs of a project.

Calm and In Control
We are calm and in control, always approachable and reassuring. While we are friendly and accommodating. We bring an incredible work ethic and dedication to your project.

Humble and Passionate - We Love What We Do.
We put our egos in check to really drill down to your needs and deliver democratic results. Our team is always having fun and leading with a sense of humour. Reducing your stress makes the process enjoyable for everyone.



We are honoured to have received numerous awards that recognize our commitment to create spaces that will empower our clients. Here are a few...

We're living in a time of incredible consumption, and everything's about economics and everything's about cash flow, and I think Jonathan Kearns has an ability to stand away from that stuff and feel something that motivates him. He's motivated to do his work in a way that I think a lot of architects and a lot of designers aren't. What I'm saying is that he's got a depth of emotion and feeling, and it comes out.
Bruce Kuwabara
Chair of the Board of Trustees, Canadian Centre for Architecture
The Canadian Canoe Museum defers to the landscape and the need to integrate with it, as opposed to standing out like a Bilbao. It’s not architecture as an object, but rather architecture linked to experience. The most significant thing beyond the integration in the landscape is the experience from within, and how the museum frames the view to the outside. It’s a very soft and generous approach to building.
