Simon Stevenson

It was growing up in the English gardens of his youth that Simon first developed his love of  all things gardening.


He founded Leaside Landscaping in 1982, while studying in Ryerson's Landscape Architectural Technology program. Since then, he’s taken the company from a 3-man crew in an old jeep to a professional outfit with qualified specialists in design, horticulture, carpentry, stone masonry and sustainable landscaping. During the summer months his fleet of forest green trucks are a familiar site around Leaside and surrounding neighbourhoods. He is a long-term Leaside resident and a proud supporter of the community.
