Assumptions and method
Commodity prices are the Regulated Price Plan prices effective November 1, 2026. Time-of-Use assumes 64% off-peak, 18% mid-peak and 18% on-peak use. Usage is multiplied by a typical 1.035 line-loss factor.
Delivery and regulatory charges are representative estimates for each density class, not any specific utility's tariff. Regulatory charges are modelled at about 0.62¢/kWh plus a $0.25 administration charge.
The Ontario Electricity Rebate (15.7%) is applied to the pre-tax subtotal, and HST (13%) is calculated on the subtotal. Customers on the Ontario Electricity Support Program receive an additional monthly credit.
