Hydro-Québec spokeswoman Marie-Hélène Deveault said the number of outages peaked at around midnight, with 47,000 clients across the province in the dark.
By late this morning, more than 17,000 homes were still without electricity.
“We had a lot of damage on the grid,” Deveault said.
She said winds of up to 90 kilometres an hour knocked down trees and large branches. That, coupled with the torrential rain, thunder and lightning were responsible for the damage.
A number of homes in the Laurentians, Montérégie, Laval and downtown Montreal are still experiencing outages.
A weekend of rain has left some parts of the province flooded, particularly after two rivers in Quebec City overflowed Friday night.
Deveault said Hydro-Québec clients who still don't have their power should call 1-800-790-2424.Suggest a correction
