Strong winds cut electricity to hundreds of thousands of Quebec homes

Published: 

Strong winds caused trees to fall, damaging cars and property in Montreal and across Quebec.

Stormy weather overnight, including strong winds, has cut power to homes in almost every region of the province Tuesday morning. The strong winds are knocking over hydro poles and trees, causing damage throughout the province.

High winds knock out power, cause damage across Quebec Strong winds up to 120 km/h toppled trees and power lines across Quebec, leaving nearly 100,000 without power and causing widespread damage.

8 p.m.

About 90,000 households remain without power across the province. The region most affected is Montérégie with 25,806 outages, followed by Lanaudière with 21,992 outages and the Laurentides with 11,718.

4 p.m.

At about 4 p.m., approximately 175,000 Hydro-Québec customers were without power, dropping from a high of about 320,000 at noon.

“What makes this event unique is that many regions are affected at the same time,” Pascal Poinlane, a spokesperson for Hydro-Québec, told The Canadian Press.

Urgences Sante says it didn’t see a rise in calls related to the weather, despite many trees and hydro poles falling, causing damage to cars and property.

Environment Canada says the yellow level wind warning has ended for the Montreal, Laval and Vaudreuil areas, meaning damaging winds are no longer expected.

Power outages have now dropped to fewer than 200,000 addresses across Quebec, for a total of 193,540 clients still in the dark.

A yellow wind warning remains in effect for the Montreal, Laval and Vaudreuil areas, according to Environment Canada.

Southwesterly winds gusting nearly 90 kilometres per hour are expected early Tuesday afternoon, but are expected to gradually decrease.

12:15 p.m.

Hydro-Quebec published a series of social media posts updating Quebecers on the power outage situation.

In the posts, the Crown corporation confirmed that most of the electricity failures were caused by vegetation collapsing onto the distribution network.

It added that there are some significant breaks caused by gusts exceeding 90 km/h, including a series of seven broken poles on a country road in Verchères, in the Montérégie region.

The hardest-hit regions, the public utility company notes, are the Montérégie, Lanaudière, the Laurentians, Montreal, Quebec City, Laval, Outaouais, Mauricie and Chaudières-Appalaches.

Winds are expected to continue throughout the day and could cause further power outages.

Gusts of up to 120 km/h are expected in eastern Quebec, said Hydro-Quebec.

“Given the scale of the event, and therefore the number of locations requiring service, it is unfortunately not possible to provide a specific restoration timeframe for each location,” the corporation said. “However, it is clear that we will not be able to restore service to all affected customers today.”

“The fact that high winds are continuing throughout the day will also slow down our work, as this complicates travel and sometimes prevents us from responding for safety reasons.”

Hydro-Quebec says there are more than 1,500 people on the ground working to restore service, and the company has called on private contractors to join its teams to speed up the restoration process.

At this time, there are 255,394 blackouts remaining.

Avoid touching power lines

Hydro-Québec is urging residents to avoid touching power lines lying on the ground.

“You must stay at least 10 metres away from power lines because they may still be live,” and you should not attempt to move them, either directly or indirectly—for example, using tree branches.

Wind warning

Environment and Climate Change Canada (ECCC) has also issued a wind warning for the Greater Montreal area.

“Damage to roofs, fences, branches or soft shelters is possible,” the agency notes. “There is a risk of injury due to flying or falling debris.”

Winds are expected to gradually decrease at midday.
