Winter storm causing school closures, transportation disruptions in parts of Ontario

A huge snowstorm continues to blast southern Ontario and parts of Quebec.

The city of Toronto and other centres were brought to a standstill today with major highways having to close for a time.

Environment Canada had issued snowfall or blizzard warnings for a stretch of the province but some of those have since been lifted.

Dozens of flights to and from Toronto's Pearson airport were also delayed or cancelled this morning.

The region was forecast to get as much as 50 centimetres of snow.

Canada Post has issued a red delivery service alert for southern and eastern Ontario as a fierce storm hits the province.

Letter carriers have been pulled off their routes, there are widespread school closures, flight delays and cancellations and highway closures.
