The document examines the devastation of Lytton in 2021 and proposes a reconstruction framework based on 'physiological foundations' to ensure climate resilience. It highlights the Kanaka Bar Indian Band's proactive investments in site-specific weather monitoring, gravity-fed water systems, controlled-environment agriculture, and passive housing design as scalable models for 62,000 other high-risk Canadian communities.

The document examines the 2021 extreme heat emergency's impact on five First Nations in British Columbia, categorised as urban (Tsleil-Waututh), rural (Kanaka Bar, Adams Lake, and Líl̓wat), and remote (Haíɫzaqv). It highlights how colonial housing policies created systemic vulnerabilities, while Indigenous kinship and cultural values provided protective resilience. Key findings include the severe disruption of food sovereignty, the failure of traditional water-based cooling due to rising temperatures, and the success of fuel-switching to heat pumps in remote areas. The report argues for trauma-informed, site-specific heat planning that moves beyond hazard-specific silos and integrates Indigenous knowledge.
