Flights Tuesday morning have been cancelled at Windsor Airport due to the freezing rain.
The ice pellets and freezing rain overnight has left a blanket of ice over the region.
The next arrival is Sunwing scheduled for 2:20 p.m.
The next departure is Porter at 2:15 p.m.
Travellers are asked to call ahead to check on their flights.
The mix of snow, ice pellets and freezing rain also forced the cancellation of school buses across Windsor-Essex and Chatham-Kent on Tuesday.
