"Her firm is a rare example in a roster of emerging Toronto practices that has loosened the iron grip on the Toronto market that large, established corporate firms have enjoyed for a long period of time. Modest budgets, simple material palettes, industrial design, defensible space, historic preservation as well as the experience of outdoor civic and interpretative spaces can be used to define future agendas of this young practice." Editor, Canadian Architect

"Not a week goes by and we don't think what a beautiful home we have. Such enduring beauty and function."

"I would like to congratulate you on your outstanding achievement of Award of Merit from ARIDO (the Association of Registered Interior Designers of Ontario).  R.H. McGregor was my grandfather. I am sure he would be so proud of your design. I love that you chose the name 'The Commons' as that was where he spent most of his time being in Parliament. I personally am very proud of your work that bears my family name. My sincere thanks for a spectacular, fabulous design." Roxanne McGregor, The Commons
