WestJet says 16 of its planes have been grounded after a massive hailstorm hit Calgary earlier this week.
The Calgary-based airline says those aircraft — 10 per cent of its fleet — need substantial repairs and inspections before they can fly again.
The carrier also says 84 of its flights were cancelled Wednesday, with 106 cancelled Tuesday and 58 on Monday.
The Calgary International Airport was pummeled by hail on Monday evening, forcing parts of its domestic terminal to close for repairs for an undetermined time.
