The hamlet of Tuktoyaktuk avoided structural damage during a Beaufort Sea storm surge due to a $54 million shoreline revetment project completed in July 2025 using the federal Disaster Mitigation and Adaptation Fund (DMAF). While existing boulder defenses protected the harbour, disappearing sea ice and warming ocean temperatures continue to accelerate coastal erosion and permafrost thaw. To secure long-term protection for critical infrastructure like the airport and fresh water reservoir, the Inuvialuit Regional Corporation submitted a joint funding application for Tuktoyaktuk, Sachs Harbour, Paulatuk, and Ulukhaktok under review as of spring 2026. The community ultimately plans to relocate to safer ground on Inuvialuit lands while exploring nature-based shoreline reinforcement in the interim.
