The Ontario Pumped Storage Project Initial Project Description – Plain Language Summary presents an incomplete, proponent-favourable characterization of a project with potentially severe, long-duration, and in some cases irreversible environmental consequences. The most critical gaps are the absence of a cumulative effects assessment, the inadequate treatment of fish entrainment and contaminant mobilization risks, the incomplete Species at Risk inventory, the absence of OCCIA 2023 considerations, and the lack of a genuine alternatives analysis.
