We believe in the power of collaboration to champion the transition towards 100% sustainable energy.

For over fifteen years, the Ontario Sustainability Energy Association (OSEA) has been championing a more sustainable energy economy in the province and has led the charge for sector transformation, garnering support from diverse areas of the energy industry.

An Ontario powered, heated, cooled and transported by a portfolio of sustainable energy – that is what OSEA envisions for our current and future communities, and we are advocating for policy and regulatory change to ensure this vision comes to fruition. 

With our track record, we have the proof, the courage, and the drive to create a more sustainable Ontario and we know that together we are powering Ontario’s prosperity, creating good jobs, fortifying resilient communities, and enabling healthy environments.


To cultivate a sustainable future in Ontario through environmental stewardship, economic development, and social reform.


The Ontario Sustainable Energy Association (OSEA) advocates for its members and the public to provide education and promote sustainable initiatives through policy development, B2B collaboration and public awareness campaigns.
