Powerful lightning strikes took out power to about 10 homes in the town of Inuvik, N.W.T., Sunday night.
It also caused problems for television and radio, including CBC North’s radio signal.
The lightning storm happened during an unusually heavy rain in the town of about 3,500 people.
"The crews are out this morning making repairs, we expect that it was transformers or fuses that were hit by lightning strikes," said Bob Kelly, spokesperson for the Northwest Territories Power Corporation.
CBC has a technician in Inuvik who is working to restore radio broadcasting.
This is the second lightning storm in only a few days. Last Thursday, lightning hit and cut power to about 70 homes for about 10 hours.
