Gerald Grieve graduated from the University of Toronto with a Bachelor of Landscape Architecture degree in 1980 and is a full member in good standing of the Ontario Association of Landscape Architects and the Canadian Society of Landscape Architects.



Shelley Grieve graduated from the University of Toronto with an Honours Bachelor of Science and the State University of New York with a Graduate Certificate in Education.


Since its incorporation in 1984, Shelley and I have worked together to build Gerald Grieve Landscape Group Limited (GGLG) into an award winning design/build firm.

Starting with one truck and a small team we both spent long days working on the construction sites. Our days did not end there. In the evenings I would design and prepare quotes while Shelley worked on contracts and financials.

While our team has grown significantly over the years, I continue personally to work with our clients throughout the entire design and construction process.


Our philosophy is, and always has been, to provide excellence in design and craftsmanship - regardless of a project’s size or stature.

We provide a complete range of services for our clients, with all the capabilities and expertise of a large firm, yet the hands-on approach and individual care that can only be provided by a family owned and operated business.

When our family name is on your project, you receive the best quality and workmanship. Guaranteed.

"In the hands of Landscape Architect Gerald Grieve and Oakville home owners, imagination was brought to fruition with a truly spectacular outdoor living room."

-   Style at Home, Canada's Decorating Magazine (2007)

"Gerald responded with a design that divides the yard into zones, each with its own character, and a romantic relaxed look inspired by the formal English idea of formal symmetry, but without being too manicured ... the garden truly comes to life."

- Canadian House and Home’s Gardening Life (2005)

"Gerald Grieve is one of the most sought-after LAs in the tony Oakville-Mississauga corridor"
