Progressive Conservatives are calling for the firing of Hydro One's chief executive officer.
MPP Jeff Yurek says it's prompted by complaints the party's received over billing problems.
Yurek cites one business in his London-area riding receiving a bill for $233-thousand when it bill normally runs at about $4,500 a month.
Yurek says if Hydro One was any other business, the people responsible would be fired and a new team put in place.
