Eligibility for a credit | Hydro‑Québec

You may receive a cheque in the mail. If the bills were addressed to more than one person in 2018 or 2019, but you and the people in question are no longer jointly responsible for a Hydro-Québec account, or you or your company has become solely responsible for the account, you are entitled to a credit by cheque.
