Passengers at Pearson airport in Toronto endure a slew of cancellations on flights to and from U.S. cities including Boston, New York and Philadelphia.

Pearson International Airport reported a flight cancellation rate of 13 per cent as of early Sunday afternoon. A typical rate for air travel is between one and two per cent.
Most flights to and from Boston and New York were cancelled, as were many to or from Atlanta, Baltimore, Philadelphia, Hartford and other destinations in the U.S. Northeast.
A handful of flights to and from Germany were delayed.
An airport employee said the cancellations were due to stormy weather in other cities and not problems in Toronto.
