Progressive Conservatives are calling for the firing of the 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 received a bill for 233-thousand dollars when it bill normally runs at about 45-hundred a month.
Yurek says if Hydro One were any other business, the people responsible would be fired and a new team put in place.
