Ontario is transforming its electricity system to ensure a reliable, modern and sustainable power supply for the people of Ontario now and well into the future. Doing so requires significant, prudently managed investment in Ontario’s electricity system.

Working with Ontario’s energy agencies, local distribution companies and stakeholders, the OPA is playing an important role in this transformation by advising the government on electricity integrated plans, helping Ontarians to conserve energy and contracting for the various sources of supply.

This section provides information on electricity costs and how they are reflected in your electricity bill.
