Rethink 150: Indigenous Truth is collaborative project led by members of the Okanagan Syilx First Nation that encourages people to rethink the celebration of Canada 150 by drawing attention to the settler colonial context of the Okanagan and the long history of Indigenous peoples on their lands. Rethink 150: Indigenous Truth uses artistic interventions in multiple media, scales, and locations to tell truths about Syilx generosity to early settlers, residential schools, stolen lands and damaged ecosystems, and ongoing Syilx vitality. We are working to open public space for these truths, to generate cross-cultural listening and learning, to envision new ways of living together, and to leave a lasting, material legacy that can help transform landscapes and communities in the Okanagan.
