A 2025 public opinion poll conducted by Innovative Research Group for the Ontario Waterpower Association shows strong and consistent support for waterpower across the province. Eighty-one percent of Ontarians back the use of waterpower for electricity generation, with support levels steady across all regions, ranging from 77% in Central Ontario to 86% in the South. Among respondents familiar with the technology, support rises to 91%, suggesting that increased awareness correlates with stronger approval.
The survey indicates that reliability and local investment are key priorities for Ontarians. Most respondents said they would accept higher electricity bills - up to five percent annually - if it meant using sources that improve system reliability. A majority also preferred projects that keep more investment and jobs within Ontario, even if such projects come with higher construction costs.
Long-term value was another major theme. Eighty-five percent of respondents agreed that government investment decisions should consider total lifecycle costs, not just initial expenses. Similarly, 84% said that additional public benefits provided by waterpower - such as flood control, recreation, and local economic activity - should factor into project assessments.
