Utility outages, which have already taken place in Chatham-Kent Saturday as the weather system moves across, may occur.
Unfortunately, this might be due to a slow-moving, low-pressure system approaching the area, says Environment Canada.
The weather has left roads slippery, at a time of year when many people have already removed their winter tires.
"However, freezing rain will likely become widespread again".
It's hard to know exactly which areas will be affected, but areas closer to Lake Ontario and near the Highway 401 corridor may remain just above the freezing mark (meaning less-if any-ice buildup).
"We're ready to respond 24/7", Hydro One said in a tweet.
Residents from the GTA and beyond are sharing their photos and videos from across the region as the storm passes through their neighbourhoods.
