Who We Are

Quality Professionals, Quality Practice

Planners are skilled professionals who work to improve the quality and livability of Ontario communities. Watch the video below to find out how the Institute is the voice of the planning profession in Ontario and the role that planning plays in shaping communities across this province.


As the recognized voice of Ontario's planning profession, the Ontario Professional Planners Institute (OPPI) has the Mandate to grant the RPP designation, govern the rights and responsibilities of its members, and set academic, experience and examination requirements for membership. The OPPI Professional Code of Practice and Standards of Practice set the benchmark for quality practice among quality planning professionals.

OPPI shares information, data and ideas through the Knowledge Centre and provides leadership and Advocacy on planning issues that matter most to the people of Ontario.

OPPI represents over 4,000 professional planners and over 500 student members. Members work for government, private industry, community agencies and academic institutions in a variety of specialties across the province. OPPI is the Ontario affiliate of the Canadian Institute of Planners.

OPPI derives its mandate from the Ontario Professional Planners Institute Act and is led by a volunteer Council elected by the membership. Online nominations to participate as a member of Council are accepted annually between February 1 and April 1. Council is supported by Standing Committees, District Teams, Program Committees and Strategy Groups.

OPPI is currently pursuing legislative change to enable regulation of the planning profession. The Institute has a mandatory program of Continuous Professional Learning as a requirement of membership to ensure RPPs remain current with contemporary practice and effective in the dynamic environment facing planners today.

A not-for-profit Ontario Corporation, OPPI is funded entirely by membership fees, program and activity revenues. These may include advertisements in the Ontario Planning Journal and Naming and Sponsorship Opportunities.

Volunteer Leadership is at the heart of OPPI. Members participation is sought through District Teams, Program Committees and Strategy Groups. Members also contribute to events, oversee exams, mentor new planners, and so much more.

The Ontario Professional Planners Institute Act came into force December 9, 1994. Some key provisions include OPPI's Mandate, Protected Title and RPP Designation, Penalty for Misuse, Professional Code of Practice and Right to Practice.
