crews from Ottawa, Windsor, Manitoba and Michigan were helping local teams with their efforts.
Elsewhere in Ontario, more than 52,000 customers were still without power on Tuesday. In Quebec, 31,700 customers remained without power as of Tuesday morning. In New Brunswick, more than 40,000 customers were still in the dark, and about 2,000 were without power in Nova Scotia.
Canadian utility officials warned that some customers could be without power until Saturday.
Some U.S. states kept emergency shelters open for people without power.
The number of customers in Maine without power spiked to more than 100,000 on Tuesday, even as Central Maine Power Co. sent more than 1,000 workers to help restore power throughout the state.
That was the case, too, in Michigan, where Jackson-based Consumers Energy - the state's largest utility - said it hadn't had this many outages during any Christmas week since its founding 126 years ago. Close to 17 percent of its 1.8 million electric customers lost power during the storm that hit late Saturday; roughly 152,000 remained without it Tuesday.
At their home outside Flint, Michigan, John Potbury and his family of four lost electricity at 6 a.m. Sunday and since then they have been living in a single bedroom warmed by generator-powered space heaters.
Lights on the Christmas tree were dark, of course, but there was no power to the freezer, either. ''Even though the house is freezing cold, the freezer items were starting to thaw out,'' Potbury said.
That wasn't the greatest concern, however, for his kids, 8-year-old Jacob and 5-year-old Jackson. Potbury said he told them Tuesday, ''Santa runs on reindeer power, not electricity, so he should be OK.''
