Authorities were warning of the potential for major hydro outages as forecasts warned of an impending ice storm for a large swath of southern Ontario.
As of Friday evening, a freezing rain warning was in place for Waterloo-Wellington, Huron-Perth, Oxford-Brant and Norfolk-Haldimand.
In those areas, Environment Canada said, rain would give way to freezing rain early Saturday morning as temperatures dropped to the freezing mark.
The freezing rain was expected to continue off and on through the day, occasionally falling for hours at a time and potentially with an accompaniment of ice pellets.
In areas north of Highway 7, the precipitation could change to snow by Saturday night.
A second round of freezing rain was expected to arrive late Saturday night and potentially last well into Sunday before temperatures warmed enough for it to become rain.
Forecasts were calling for 10 to 20 mm of ice accumulation by Sunday morning, with more possible in localized areas.
To the north, there was a snowfall warning in place for Grey-Bruce, with Environment Canada forecasting 15 to 20 cm of snowfall mixed with occasional ice pellets.
