About 200 flights in and out of Toronto have been cancelled as the forecast for Tuesday evening calls for whiteout conditions, gusty winds, and up to 30 centimetres of snow in parts of southern Ontario.
Bad weather is not the only reason for the cancellations, but many of the flights were supposed to travel through areas in the path of a much-hyped snowstorm expected to hit later today and Wednesday, said Greater Toronto Airports Authority spokesperson Trish Krale.
Flights have been cancelled to many U.S. cities, such as Cincinnati, Dallas, Pittsburgh,
Detroit, Boston and Chicago.

On the ground, Environment Canada is urging motorists to exercise caution on the slick roads.
“Travellers should be prepared to adjust plans accordingly as this is likely going to be a large and potentially dangerous winter storm,” said the weather authority, in a statement.
Touted as possibly the worst snowstorm in recent memory by Environment Canada, 20 to 30 centimetres of snow are expected to start falling this afternoon in the Greater Toronto Area.
The storm will ease into the area with scattered flurries and pick up by Tuesday night. It is expected to taper off by Wednesday afternoon. Temperatures will see a high of -6C, but it will feel much colder with the wind chill.
Gusty winds are expected to hit up to 60 km/h, Environment Canada said.
The winter storm warning also includes Barrie, Peterborough, Cornwall, Parry Sound, Ottawa and Kingston.
The storm is also wreaking havoc south of the border with snow, rain, tornadoes, and ice. Kansas City, St. Louis and Milwaukee are bracing for what may be one of the biggest snowstorms.
Environment Canada senior climatologist Dave Phillips said the storm will affect 100 million people in North America.
