More than 200,000 still without power in the Ottawa-Gatineau area

Tens of thousands of customers remain without power in the National Capital Region Thursday after what Hydro Ottawa described as the worst ice storm in the area since 1998.

• 53,000 Hydro Ottawa customers don't have power.

• 114,000 Hydro Quebec customers in the Outaouais don't have power.

• 88,000 Hydro One customers in eastern Ontario don't have power.

Overall, about 270,000 Hydro Ottawa customers were affected in some way by Wednesday's freezing rain, said Joseph Muglia, Hydro Ottawa's director of system operations and grid automation, at a 10 a.m. news conference Thursday.

About 53,000 of them remained without power as of 3 p.m.

The company expects its 20 worst outages — affecting about 45,000 customers — to be resolved by noon, Muglia said.

Smaller outages will take an unknown number of days to get to, and Hydro Ottawa is working with the city to get people in those areas what they need.

"This is a multi-day event, I want to stress that. ... It's slow-moving, it's very organic," Muglia told reporters.

"Yesterday, we experienced one of the most devastating ice storms since 1998. We've had ice storms since then, as recent as 2017-2018, but nothing, nowhere near what we saw yesterday."

Still working on major storm resiliency, preparedness

Repair efforts were slowed down by lightning and falling trees and branches that made conditions too unsafe for crews, Muglia said.

As of Thursday, a full complement of workers is on the ground, supplemented by contractors and staff from other jurisdictions.

The ice storm comes not quite a year after the powerful May 2022 derecho wind storm, which caused the worst damage Hydro Ottawa had seen across the city in decades. Since then the utility has been working on its storm preparedness and resiliency, and Muglia said that will continue to be a big focus throughout 2023.

"We're all seeing that these major events, that are supposed to be like 100-year storms, are happening a month apart or three months apart. And so it's been a very quick learning curve for us to make sure that we've got our resilience in place, our people are able to be refreshed and get ready for the next storm.

"So we're working on that. We're working on our infrastructure, we're working on our storm hardening."

Meanwhile, across Quebec, more than one million Hydro Quebec customers were without power early Thursday, including 121,000 in the Outaouais.

MRC des Collines police said that 95 per cent of residents there are still without electricity.

In Hydro One's east Ontario region, about 88,000 customers had no power Thursday, according to its online outage map. The Arnprior, Perth and Winchester areas were particularly affected.
