On Wednesday, September 9, 2026, between 9 a.m. and 2 p.m., Hydro Westmount will carry out work on its electrical network. This work will result in a temporary power outage in the area bounded by Upper Lansdowne, Sunnyside and Roslyn avenues.
In the event of a cancellation, particularly due to weather conditions, the work will be postponed to the next business day. If the work cannot be completed within 48 hours of the scheduled date, affected residents will be notified in writing of a new date.
