UPDATE: Air Canada outage resolved at Pearson
All systems are back up an running, but a computer system outage caused lengthy delays at airports across the country on Monday.
Angry passengers took to Twitter to complain about long lines and flight delays during the March break travel rush.
The airline tweeted that it was ``experiencing an interruption'' at its contact centres and website and is working to restore service as soon as possible.
That service was restored around 1:30 on Monday afternoon.
The disruption comes two weeks after the airline had a computer issue that disrupted web and mobile check-ins and call centre operations and temporarily delayed boarding on some flights.
