Équiterre's offices are located on Indigenous lands that have not been ceded by treaty, which we now call Montreal and Quebec City, where different Indigenous peoples have interacted with each other. We recognize that Indigenous peoples have been protecting their territories since immemorial times and have been using their traditional knowledge to guard the lands and waters. We are grateful to live on these lands and are committed to continuing our efforts to protect them. As an organization concerned with environmental and social justice, Équiterre respects the important links between the past, the present and the future. We recognize the road ahead in implementing our mission, while building relationships with Indigenous peoples in humility, respect and dialogue.
