Ontario's Electricity Hub

The Independent Electricity System Operator (IESO) works at the heart of Ontario's power system – ensuring there is enough power to meet the province's energy needs in real time while also planning for and securing energy for the future.

Advisory on solicitations
The former Ontario Power Authority does not call consumers to solicit participation in its programs. No OPA residential programs require door-to-door sales calls or the inspection of any heating and cooling equipment and the OPA does not charge a fee to participate in any of its conservation programs.
