The Ontario Sustainable Energy Association (OSEA) is Ontario’s lead advocate, facilitator and catalyst for sector transformation and the transition to a more sustainable energy economy. We are championing policy and regulatory change for a more sustainable society powered, heated, cooled and transported by a portfolio of sustainable energy. Who does OSEA represent? OSEA serves as an advocate for individuals, manufacturers, installers, developers, municipalities, First Nations, unions, farmers, co-operatives and other community organizations, NGO's and other associations supportive of, and engaged in, the full portfolio of sustainable energy solutions. Who does OSEA work with? Our partners include likely and unlikely allies who want to be part of OSEA's collaborative efforts to grow the pie for all Ontarians creating a more sustainable province and who want to help tackle the root causes of social friction during the energy transition to a portfolio of 100% sustainable energy.
