In 2022, the British Columbia Technical Working Group on Missing Children and Unmarked Burials began developing one-page summaries of key technical issues in an accessible format to help those involved in ground searches for missing children. This work was expanded in 2025 by the Reconciliation Network Project.
Ground searches for ancestors are complex. If you need support, please contact the National Residential School Crisis Line (1-866-925-4419). Links to additional supports can be found on the CAA Working Groups' information page.
The Institute of Prairie and Indigenous Archaeology at the University of Alberta has a reference page of resources that provide important guidance for ground searches Community Resources | Institute of Prairie and Indigenous Archaeology (ualberta.ca). These include detailed guidance on technical methods: Planning and Research Guides | Institute of Prairie and Indigenous Archaeology (ualberta.ca).
The National Advisory Committee on Residential School Missing Children and Unmarked Burials has compiled useful resources for all facets of IRS searches.
