TORONTO – Superstorm Sandy is starting to peter out in southern Ontario and Quebec, though the rain is expected to stick around for a few more days.

The post-tropical storm lashed central Canada with rain and very high winds overnight and is bringing heavy rainfall to parts of the Maritimes today.

The wind warnings have all been cancelled except for the Sarnia area of southern Ontario, where winds of up to 100 kilometres per hour will continue through the morning.

Sandy left in its wake 150,000 customers without power in Ontario, about 50,000 in Quebec, and one Toronto woman dead after she was hit by a falling sign.

Geoff Coulson with Environment Canada says remnants of the storm will continue to bring storm surges to the St. Lawrence River and rain to central and eastern Canada, turning into snow and ice pellets in northern Ontario.

The U.S. East Coast was hardest hit by the storm, which left at least 18 people dead and millions without power or mass transit.
