Hydro sends more teams to help restore the power of Vancouver Island and the southern bays of the islands, as more than 24,000 customers still do not have electricity.
The administration says there are 800 people working around the clock, but in spite of that, some people will still be powerless for days.
"Unfortunately, we will have some customers in the hardest hit areas through Christmas," said Tania Rish, a spokeswoman for BC Hydro.
Several hundred users still have no electricity in the areas of Nadezh and Pemberton, but were expected to return to the network later on Monday.
While noon PT Monday, BC Hidro said that the following communities are likely to be without the power of Christmas:
- Bamfield / West Bamfield / Nitinate
- The island of Tethys / Penelucut
- Isle of Protection
- Parker Island
Teams from other parts of the province, as well as Alberta and the east coast, were also entered.
In the midst of a massive storm on Thursday, nearly 400,000 users were powerless.
One of the challenges for Hydro teams is the number of trees that have been knocked down and block roads and side streets, which makes access to some of the neighborhoods more difficult.
Public Security Minister Mike Farnworth said it was too early to say what the clean-up and response would cost, but the repair of the damage would be expensive.
"What's incredible is that you have men and women who give up Christmas holidays," Farnworth said. "They work around the clock and they work in challenging, often dangerous conditions."
