Porter Airlines says its flights have resumed service, just over two hours after the Toronto-based airline announced that service was suspended due to a widespread system outage.
A spokesperson told Global News that five flights were cancelled as a result, affecting 400 passengers.
All affected passengers will be given the option of traveling today if they so choose, or can travel tomorrow or get a full refund.
“We will be reviewing the circumstances to determine specifically what caused the issue,” the spokesperson said.
The airline had previously issued a tweet at around 4:30 p.m. ET saying that all arriving and departing flights were grounded.
Porter operates flights out of Toronto’s island airport to and from cities across Canada, and seven locations in the U.S.
