Thousands face no power after ice storm in North America
Snow and ice are causing severe disruption to parts of Canada and the US
Hundreds of thousands of households in Canada and the northern US are facing a Christmas without electricity after a severe ice storm hit on Sunday.
About 400,000 in eastern Canada and 280,000 in the US state of Michigan were without power as of Monday.
In Toronto, a power firm has said power will be restored for most residents by Thursday, but that some may not have electricity until the weekend.
The city has opened several warming centres across the city.
Temperatures as low as -15C (5F) are expected southern Canada over the next few days.
At least 11 deaths have been blamed on the storm system in North America, five of them in accidents on ice-covered Canadian roads.
'Truly catastrophic'
An estimated 10-30 mm of ice built up on trees and other surfaces in the greater Toronto area during the storm.
Sheets of ice fell from buildings and off moving vehicles, Canadian TV channel CBC said.
Via Rail warned customers travelling between Toronto and Montreal, Ottawa and New York to expect delays on Monday.
Toronto Mayor Rob Ford resisted declaring a state of emergency, but said getting electricity to hospitals and community housing should be a priority.
Efforts to reconnect power continued through the night and Toronto Hydro said it was able to restore electricity to about 85,000 customers in the Toronto area.
Another 100,000 customers were without power in wider Ontario as well as about 50,000 in Quebec and some 6,000 more in New Brunswick.
Earlier, Toronto Hydro's chief executive officer Anthony Haines said it was "truly a catastrophic ice storm that we have had here, probably one of the worst we've ever had".
Officials warned high winds on Monday could lead to falling branches and more felled power lines.
'Challenging week'
Flights were delayed or cancelled due to the storm in the US and Canada, at one of the busiest travel periods of the year.
In New York's St Lawrence County, almost two inches (51mm) of ice had accumulated on Sunday.
Tree damage during the storm has been described as extensive
Freezing rain fell over the weekend, causing icicles to form
Although the storm has moved on, temperatures continue to be very low
Vehicles had to drive round the ice covered branches on Toronto streets
Crews are working to restore power to tens of thousands of homes in Toronto
More than 400,000 people were also left without power in the northern US after the storm.
About 280,000 were still without power in Michigan, including 80,000 in Detroit.
A spokesman for one of the Michigan electricity firms told the Detroit Free Press it could be the end of the week before power is restored.
The US National Weather Service warned "another round of snow and ice" was expected for New England on Monday.
Parts of Maine are expected to see as much as half an inch of ice.
