About the OCAA

Our Roots

The Ontario Commercial Arborists Association (OCAA) was founded by a passionate group of commercial arborists committed to advancing the arboriculture profession in Ontario. Since its inception, the OCAA has worked to elevate industry standards, support arborists in their careers, and ensure the safety and health of both workers and the public.

    Creating opportunities for commercial arborists to collaborate, share ideas, and build a stronger voice for the sector.

Our Industry Network

OCAA works in collaboration with key organizations to strengthen the industry and expand training and safety awareness:

  • The Board of Directors is the governing body of the Ontario Commercial Arborists Association (OCAA). It is responsible for overseeing the strategic direction, financial stewardship, and overall governance of the organization. Directors are elected by the membership and serve to represent the collective interests of members across the arboriculture industry. The Board ensures compliance with the Association’s mission and bylaws, approves major policies, and provides guidance to the Executive Manager. Regular board meetings are held to review operations, plan initiatives, and make decisions that support the growth and integrity of the Association.

  • OCAA Committees are formed by the Board of Directors to focus on key areas that support the Association’s mission, events, and ongoing initiatives. Committees may be standing or temporary (ad hoc) and are made up of a mix of board members, association members, and non-members who bring relevant expertise or interest. This inclusive approach encourages broader industry engagement and allows individuals who support the arboriculture profession to contribute meaningfully to the work of the Association. Committees provide input, develop recommendations, and assist with program development and implementation, all under the direction and approval of the Board of Directors.
