To opt out of having a next-generation meter installed, you must be the person responsible for the electricity account at that address. If the electricity account is in your tenant’s name, the decision of whether to opt out is up to them.
As the Régie de l’énergie [Québec energy board] concluded in its decision, “the conditions of service cannot govern the contractual relations between a landlord and tenants or between co-owners. The solution to this problem is to be found in private law, not the conditions of service.”
