About 4,500 Montreal-area addresses were still without power by 11 a.m. Sunday, down considerably from the 20,000 homes affected by Hydro-Québec outages Saturday as a result of severe weather.
Thunderstorms and rainfall of between 100 and 150 mm across the city meant that service was interrupted by the utility in a number of municipalities, including Pierrefonds and Dollard-des-Ormeaux.
