Who We Are

Ontario Land Trust Alliance (OLTA) empowers and supports highly effective, well-governed land trusts that engage their communities in land conservation.

OLTA builds capacity through training and educational programs; connecting land trusts to each other, resources and their communities; leading and supporting on-the-ground conservation work; sharing knowledge and best practices, reducing financial barriers to land conservation, promoting organizational excellence, providing access to current research and acting as a voice for land trusts among the public, governments and other stakeholders. Our impact is Ontario-wide through at least 50 connected charities and communities.

OLTA’s local land trust members and associate conservation organizations collectively own and steward over 108,000 acres across Ontario, engaging the support of thousands of volunteers and supporters annually.

Ontario Land Trust Alliance currently requires all of its Land Trust Members to adopt the Canadian Land Trust Standards and Practices.

OLTA is a registered charity – 869437517RR0001.


To strengthen land conservation in Ontario by building and supporting a strong land trust movement.


OLTA works to advance overall excellence in community land conservation in Ontario as a nonpartisan and independent organization that promotes best practices and organizational excellence. It aggregates and shares land trust data and partners in research and education to contribute conservation planning expertise. It also continues to operate and expand as a trusted funding program administrator to support the sector.


OLTA was established in 1997 as a committee of the Federation of Ontario Naturalists known as the Ontario Nature Trust Alliance with 14 founding members. In July 2002, with a membership of 23 land trusts, it was decided to incorporate as a new independent organization named the Ontario Land Trust Alliance. This change better reflected the activities of all its members, which now included recreational, agricultural and built heritage as well as natural heritage properties.
