Our granting principles The Ontario Trillium Foundation observes the following granting principles: The voluntary sector plays a critical role in building healthy and vibrant communities. OTF will work to achieve its mission by supporting the work and enhancing the long-term capacity of organizations in the sector. OTF grants will support organizations in the arts and culture, environment, human and social services and sports and recreation sectors. In small communities with a limited voluntary sector, OTF may support the work of municipalities or libraries in order to achieve its mission, specifically in the arts and culture and the sports and recreation sectors. Respect for diversity, inclusion and volunteerism are fundamental to the work of OTF. OTF offers three types of time-limited grants: operating, project and capital.
