Large-scale development projects in Canada have transformed landscapes in ways that often escape public view, with many sites deliberately shielded from visibility. This project examines how environmental change becomes visible and politically meaningful through a mixed-method approach. Using the Site C Dam in British Columbia as a case study, we develop a convolutional neural network (CNN) trained on satellite imagery to identify and visualize environmental degradation, linking those results to the institutional and policy factors that may have caused it. We combine computational image analysis with document review of environmental assessments, consultation records, and policy reports to explore how accountability and oversight operate within Canada’s system of environmental governance. Building on Rufat et al.’s (2015) social vulnerability framework, the analysis considers how environmental change and governance decisions produce unequal impacts, particularly for Indigenous and low-income communities. The project integrates machine learning with policy analysis to evaluate how visibility, accountability, and institutional design interact in Canadian environmental decision-making.
