In 2004, rival airline Air Canada accused WestJet of industrial espionage and filed a civil suit against WestJet in Ontario Superior Court. Air Canada accused WestJet of accessing Air Canada confidential information via a private website in order to gain a business advantage. On May 29, 2006, WestJet admitted to the charges leveled by Air Canada and agreed to pay C$5.5 million in legal and investigation fees to Air Canada and donate C$10 million to various children's charities in the names of Air Canada and WestJet.
