Dozens of flights have been cancelled at Toronto's Pearson airport due to fog blanketing the American northeast.
Airport officials say 120 flights have been cancelled over the past 24 hours at Pearson.
An Air Canada spokesperson told CBC that passengers should check to ensure their flights are on schedule.
Flights have also been cancelled at the Billy Bishop Toronto City Airport, where Porter Airlines was advising its customers Tuesday to confirm their flight status before arriving at the airport.
Air Canada warned that its own flights leaving the island airport “may be impacted by forecasted low ceilings, fog and reduced visibility."
