Who we are

Started in 1973, Landscape Ontario Horticultural Trades Association (LOHTA) is a vibrant association representing over 2000 horticultural professionals. Our members include landscape, maintenance and snow management contractors, landscape designers, lawn care operators, garden centre owners, arborists, nursery growers, interior landscapers, and irrigation and landscape lighting contractors.

LOHTA members have a commitment to maintain confidence and trust in the profession of horticulture and to encourage and support education and research within the horticultural field. LOHTA also helps fulfill its pledge to elevate the green industry and enhance our environment through various public events like Canada Blooms, and participation in local home shows and community events. Members of LOHTA's nine regional chapters donated time and materials worth over $500,000 last year through projects to green their communities.

LOHTA is governed by an elected Provincial Board of Directors, which volunteers its time and effort to oversee the many programs and functions of the association. Landscape Ontario membership is organized by a local Chapter system. The opportunity for professionals to network in order to share ideas and brainstorm potential solutions to problems is one of the founding principles of the association.

Landscape Ontario also has various sector groups to address the specific needs of the various industry sectors. These groups of volunteers meet regularly to deal with sector-specific issues and initiate solutions.

Landscape Ontario members are proud of their world-class association and realize it would not be possible without the thousands of hours its hundreds of volunteers contribute on an annual basis to promote the benefits of the industry and the joy and beauty of outdoor living.

Landscape Ontario has also formed numerous relationships with other organizations, associations, municipalities and educational institutions who share the common goal to promote the benefits of landscaping and horticulture. Many of these organizations can be found in the links section of our website.
