The EO sector has seen an exponential increase in data acquisition, analytics systems, and delivery systems which has been simultaneously matched by open-access policies, cost reductions, and user-driven data demands. However, consultation efforts with EIA practitioners have shown that the increased uptake expected from these improvements has not been realized. This indicates persistent barriers, including: (1)-EO science awareness; (2)-data availability/usability; and (3)-technological uptake capacity. The Earth Observation for Cumulative Effects – Phase 2 (EO4CE-2) research program, led by Natural Resources Canada’s Canada Centre for Mapping and Earth Observation (CCMEO), was initiated in 2024/25 and aims to improve the availability and application of EO-derived environmental status and trends data to support regional assessments and impact assessments. Leveraging decadal records of satellite imagery and advanced methodologies such as AI and machine learning, the EO4CE-2 program has developed a library of EO-based data products, facilitating more comprehensive analysis of land use, water resources, lake and river ice, vegetation and terrain stability. Looking forward, challenges remain in integrating EO within the impact assessment framework including supporting major project development proposals, enhancing monitoring of active projects, and assessing post-operation reclamation requirements. Addressing these challenges requires continued collaboration across government, industry, consultants and Indigenous communities, as well as sustained investment in EO-based functions. This presentation will discuss EO4CE-2’s progress, its impact on the impact assessment landscape, and the path forward for embedding EO into Canada’s regulatory and decision-making processes.
