More than 56.000 hydro customers were without power in eastern Ontario and southwestern Quebec Monday morning after a powerful storm swept through the provinces on Friday.
Hydro crews in Quebec and Ontario are gradually restoring power, but some people might be left in the dark until Tuesday.
The storm, which brought winds up to 100 kilometres an hour in some places, uprooted trees, brought down power lines, and even overturned some cars.
Quebec was particularly hard hit, with 44,000 in the province still without power Monday morning. At the height of the storm, about 560,000 Hydro Québec customers had lost electricity.
Power was restored to over 90 per cent of customers in Montreal but other areas north of the city could take longer, said a spokesman for Hydro-Québec.
Louis-Olivier Batty said workers still need to clear away trees and branches from some power lines.
Trouble spots in Quebec include Laval, the Laurentians, Lanaudière as well as the Outaouais region near Ottawa.
In the Ste-Rose district of Laval, Que., Monique Lefebvre has been without electricity since Friday.
She said she couldn't believe the amount of damage to the old trees on her street.
"Trees take a lot of time to grow," she said through tears.
In Ontario, about 17,700 Hydro One customers had no electricity on Monday morning.
A municipal worker in a Montreal suburb was killed by a falling tree during the storm, while at least 10 others were injured across Quebec.
