For over 40 years, Tumber & Associates has had the privilege of working with landscape design and build projects in the Greater Toronto Area.

There are no shortcuts to success. Good things grow and mature with time — we’ve invested the necessary time in learning and perfecting our craft.

Each member of the Tumber team brings an unparalleled passion and enthusiasm to the job site, which is evident in the quality of our work. At the same time, we’re friendly, down-to-earth, and eager to help take your ideas and transform it into a beautiful and functional outdoor space.

Over the decades, our work hasn’t gone unnoticed — Tumber is one of the most awarded companies in the landscape industry. Our dedication from the start to the finish of every project, and the experience we’ve learned along the way, is what truly sets us above the rest.

Everything we’ve learned has led us to today and we’re excited to continue to build on our legacy by working together with you to build something truly unique and remarkable.
