Some are calling it the worst ice storm ever to hit Ontario. Fallen trees and ice damaged cars and homes and knocked out power for thousands of people in southern Ontario.

Greater Sudbury Hydro has sent two crews, a total of five workers, to help Hydro One get the power back on.

The crew left Sudbury Sunday afternoon.

“From time to time, we’re called on to lend a hand when the scale of damage in an area exceeds the local utilities’ ability to get things back up in a reasonable amount of time,” Frances Caldarelli, chair of the Greater Sudbury Hydro board of directors said.

“Hydro One has to repair massive damage affecting an enormous number of people in a huge geographic area, and they need more trucks and people to get it done as quickly as possible.”

Greater Sudbury Hydro said crews are in the Guelph area to assist.

“We’re happy to be in a position to help,” Caldarelli said.

“You never know when it might be us putting out a call for assistance.”

The ice storm in southern Ontario is affecting flights in several airports, including flights to and from the Sudbury airport.

Airline carriers ask you phone ahead or check online before heading out to the airport.
