The snowfall in Toronto caused major transportation delays across the city on Wednesday as motorists manoeuvred the slippery and icy road conditions.
Global News meteorologist Anthony Farnell said between three and four centimetres of snow accumulated by mid-morning with another couple of centimetres to fall by mid-afternoon.
The Toronto area is expected to receive a total of five to 10 centimetres when the weather system finally tapers off.

A number of school buses across the Greater Toronto Area were also cancelled due to the snowy conditions. However, schools remained open.
