The Ontario Energy Board says upcoming hydro rate cuts mean the average bill will go down about 41 dollars to about 121 dollars per month.
The bills are set to drop July 1st as the remainder of cuts promised by the Liberal government come into effect.
An eight per cent cut happened at the beginning of the year and more cuts came into effect May 1st, but as of next month, officials say bills will be 25 per cent lower than last year.
Ontario's budget watchdog says the government will spend 45 billion dollars over the life of its hydro plan to save people 24 billion dollars on their bills over the next 30 years or so.
