TORONTO - Scores of flights at Canadian airports arriving from and heading to the American east coast have been cancelled due to hurricane Irene.

More than 80 Saturday flights at Toronto's Pearson International Airport involving eastern U.S. cities including Washington, Philadelphia, New York, Boston and Raleigh, N.C., are called off.

U.S. flights at airports in Ottawa, Montreal and Halifax are also cancelled.

Air Canada says flights at almost two dozen airports stretching from Newfoundland to North Carolina may be disrupted as the storm races up the east coast.

Hurricane Irene touched down in North Carolina this morning, while more than two million people in east coast states have been ordered evacuated.

The Canadian Hurricane Centre says hurricane Irene will affect eastern Canada beginning Sunday and into early Monday.
