Rivers could see even more. Canada: Unusually cold Toronto Mayor Rob Ford described the winter weather Sunday as one of the worst storms in the city's history. He said he hopes that power will be restored to the more than 250,000 customers currently without it by Christmas Day. Toronto Police Sgt. Jeff Zammit said it has been colder than normal during December, and that freezing rain and fallen trees have brought down many power lines. It truly is a catastrophic ice storm that we 've had here, probably one of the worst we 've ever had, Toronto Hydro CEO Anthony Haines told CTV Network. For customers with service, the company asked that they share the power and consider asking neighbors inside. The city has also opened warming stations.
