Who We Are








The Ontario Land Trust Alliance(OLTA) represents the network of land trusts across Ontario. Land trusts are community based, non-profit organizations primarily focused on protecting significant natural landscapes for future generations. They also provide protection to important agricultural lands and cultural heritage features. More than 85,000 acres of significant natural lands and sensitive wildlife habitat has been protected through the actions of Ontario’s land trusts.

OLTA promotes excellence in land conservation throughout its land trust member network by providing professional support and assistance, securing funding, promoting organizational excellence and representing the collective voice of the land trusts.

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


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

These land trusts are non-profit organizations with charitable status established to preserve lands of significance in the communities they serve. Ranging from regional groups in the Rainy River, Thunder Bay and Sault Ste. Marie areas, to the Georgian Bay, Muskoka, London, Oak Ridges Moraine, Kawartha, Rideau and Thousand Islands regions, these organizations are at work throughout the Province. OLTA also includes well-known provincial and national organizations such as Ontario Nature and the Nature Conservancy of Canada.
