Principal Architect, OAA, MRAIC

Trevor is the principal of TMA and is a licensed Architect registered with the Ontario Association of Architects and a Member of the Royal Architecture Institute of Canada and a member of the Toronto Society of Architects.

My sensibilities for the environment and strong connection to the Canadian landscape were informed during a lifetime of family cottaging and camping in Algonquin Park and experiencing natural beauty from coast to coast. Like many of us I find this the perfect counterpoint to the vibrancy of living and travelling in our dense urban Cities. I attended the University of Waterloo School of Architecture during which time I spent numerous work terms working on construction sites learning the realities of the building industry. In 1998 I graduated, completing my thesis work on sustainable design. In 1998 I established Altius Design and later Altius Architecture with three classmates and remained as Principal until establishing Trevor McIvor Architect in 2016. Having completed over fifty unique buildings across Ontario over the last twenty years the goal with our new studio is to build on this experience, push our ideas and continue working in this beautiful and varied landscape, both the urban and the unknown, collaborating with unique people to create buildings that harmonize them with their surroundings.
