How to tell
Look at your electricity bill: the utility’s name is on it. In Sherbrooke, part of the city is served by Hydro-Sherbrooke, a city service, and the rest by Hydro-Québec. Magog and Coaticook each have their own municipal network. Elsewhere in the Eastern Townships, it’s Hydro-Québec.
What it changes
- A new service entrance, or a 200 A upgrade. The supply request, shutoff and reconnection are done with your utility, according to its technical requirements and timelines. We handle it with you.
- An outage. You have to call the right network. For Hydro-Sherbrooke, the official outage page shows current interruptions and the number to report one (819 821-5728 according to the city’s website).
- Programs. Some Hydro-Québec programs are for its own customers; others accept municipal networks. We check what applies to you before bringing it up.
