Ontario's budget watchdog says the Liberal government will spend $45 billion over the life of its hydro plan to save people $24 billion on their electricity bills.
A report from the financial accountability officer says this means there will be a net cost of $21 billion to Ontarians over the approximately 30 years of the plan.
The $45 billion is mostly the cost of funding an eight-per-cent rebate that took effect on bills in January, but that assumes balanced budgets for the next 30 years.
