The town of Terrace Bay will remain under a boil water advisory for most of this week after a lightning strike cut power to the northwestern Ontario town's water treatment plant on the weekend. Terrace Bay Mayor Jody Davis said the strike occurred during a storm on Sunday night. And while there were no injuries, some of the plant's equipment was damaged. "A breaker was hit," Davis said Monday. "One of the transformers, which is for the water treatment generator, emergency generator, it got fried."
