As Air Canada had employed a scorched earth policy to prevent the Onex proposed acquisition as one of its lines of defence, it had burdened itself with onerous contracts with almost all of its suppliers. As a result, on 1 April 2003, Air Canada filed for protection under the Companies' Creditors Arrangement Act; it emerged from this protection on 30 September 2004, 18 months later. During the period of bankruptcy protection, the company was subject to two competing bids from Cerberus Capital Management and Victor Li. The Cerberus bid would have seen former Prime Minister Brian Mulroney installed as chairman, being recruited by Cerberus' international advisory board chair Dan Quayle, the former Vice-President of the United States. Cerberus was rejected because it had a reputation of changing existing employee pension agreements, a move strongly opposed by the CAW. At first, Air Canada selected Victor Li's Trinity Time Investments, which initially asked for a board veto and the chairmanship in return for investing $650 million in the airline. Li, who holds dual citizenship from Canada and Hong Kong, later demanded changes to the pension plan (which was not in his original takeover bid), but since the unions refused to budge, the bid was withdrawn.
