It appears the bad weather isn't ready to take a break. US National Weather Service said more snow is forecast to roll into the Great Lakes and Midwest by Wednesday morning. In Canada, five people were reported dead from apparent carbon monoxide poisoning. Police said two people in Ontario died after using a gas generator to heat their blacked-out home northeast of Toronto.

Police in Quebec said carbon monoxide poisoning was believed to be the cause of three deaths in a chalet on the province's North Shore. Earlier, five people were killed in Eastern Canada in highway crashes blamed on severe weather conditions.

In US, the nationwide death toll from the storm reached at least 14 on Tuesday, when a 50-year-old man in Knox, Maine, was overcome by carbon monoxide fumes from a generator. It was the second reported death attributed to fumes from a generator during the storm. Police in Michigan also attributed two deaths in a traffic collision that happened on Monday to the storm.

As temperatures plunged into the low single digits (below minus 15 Celsius) in Toronto where some 90,000 customers remained without power on Tuesday authorities reported a dramatic jump in calls for suspected carbon monoxide poisoning, responding to 110 calls in a 24-hour period.

Officials said they typically see 20 such calls a day. "We're looking at approximately six times as many calls," Toronto Mayor Rob Ford said as the city issued an extreme cold weather alert. "I understand they want to keep warm but you cannot do this. This is deadly."

Fire officials warned residents not to use any appliance that burns inside a home, and even cautioned against using a lot of candles. In Toronto, where 300,000 customers lost power at the height of the storm, crews from Ottawa, Windsor, Manitoba and Michigan were helping local teams with their efforts.
