Québec public service companies require bill payment 12 to 30 days from the billing date. Hydro-Québec is therefore about average, with a due date 21 days after the billing date.
The 21-day deadline has remained unchanged since 1987. With the creation of the Régie de l’énergie in 1996, Hydro-Québec indicated that it wished to maintain this bill payment deadline, which the Régie approved. It is still in effect and is presented in section 11.6 of the current Conditions of Electricity Service.
