The Indigenous Cultural Rights and Interests Toolkit (“ICRIT”, or the “Toolkit”) represents a series of integrated policy and technical guidance (“Tools”) for characterizing and exploring compensation for project-specific and cumulative effects on Indigenous cultural rights, in support of consent-based decision making on major projects and the protection and promotion of Indigenous cultural rights. Recognizing the existing gap surrounding cultural rights assessment in Environmental Assessment (EA) policy and law, the Toolkit is designed to provide support to Indigenous Groups that are engaging with project proponents and the Crown in discussions about offsetting residual cumulative effects affecting cultural rights and values within their territories. As a technical support, the Toolkit will be particularly useful in situations where a proposed project poses serious, long-term, or irreversible, impacts to an Indigenous Group’s cultural rights. By providing a framework for evaluating and responding to adverse effects, this Toolkit seeks to empower Indigenous Groups in the assessment of potential impacts to their way of life. The Toolkit may also benefit Proponents seeking greater clarity and certainty around what Indigenous cultural rights are and how they can be assessed and mitigated in collaboration with impacted First Nations, and governments that are charged with the task of appropriately assessing the cumulative risks and impacts of major projects on First Nations. While collaborative implementation with Proponents/Government and Indigenous groups, coupled with capacity support, is an option to help foster relationships, this Toolkit should not be unilaterally applied by Industry or Government. This Toolkit is first and foremost an Indigenous-led process, grounded in a community’s principles and leadership.
