The Foundation has supported Tides Canada for a variety of projects relevant to its conservation work, because Tides Canada has a successful history of working with Canadian, US, and international foundations, providing a valuable source of on-the-ground knowledge of charitable opportunities in Canada. This has been particularly helpful for US foundations that wish to support Canadian charities. Tides Canada is able to provide funds to Canadian charities, many of which are not registered under US tax law. Tides Canada also works with institutional funders who want to pool their resources toward particular goals. These mechanisms are similar to what are provided by United Way of Canada. 

In 2006, the Foundation worked with other foundations, First Nations, federal and provincial governments, and local NGO partners to create the $120 million fund to support a new ecosystem approach to logging in the Great Bear Rainforest and support associated economic development and conservation management in First Nations communities. $60 million of this fund came from the federal and provincial governments, with $5 million from the Foundation.  

The resulting Great Bear Rainforest agreement included protected areas designations, ecosystem-based management commitments, and funding for conservation management and economic development. It also set off negotiations around revenue-sharing arrangements for economic activities consistent with those land use plans.
