ACE Aviation Holdings

ACE Aviation Holdings Inc. was a Canadian holding company that was the former parent company of Air Canada. It was headquartered in Montreal. In 2012, the company signified its intent to dissolve, and was dissolved in 2024.

History
ACE Aviation Holdings was created as Air Canada emerged from bankruptcy in 2004; By the end of 2005, ACE completed restructuring and achieved reduced costs through outsourcing, automation and process simplification. One of the more significant changes was the merging of its six small airlines into Air Canada and Air Canada Jazz. ACE was not only a solution to Air Canada's bankruptcy, but also a strategic move by Robert Milton to create a portfolio of independent air transportation services companies out of what was Air Canada.

Among the companies in addition to Air Canada which was taken public after formation of ACE was the frequent flyer program Aeroplan. Aeroplan's initial public offering valued the company at US$2 billion, which was several times the valuation of the airline itself.

In 2005, ACE contributed US$75 million in equity investment to the merger of America West Holdings and US Airways Group, which resulted in US Airways emerging from its second bankruptcy.

In 2008, ACE completed its divestment of Aeroplan and Air Canada's regional airline affiliate, Jazz. After these divestments, ACE retained a 75% stake in Air Canada and a 23% stake in Air Canada Technical Services.

On May 9, 2012, the company received a certificate of intent to dissolve, marking the end of any future activities by the company.

The company planned a wind up and distribution of its assets back to its shareholders by no earlier than mid-2013. While all of the core aviation assets have been disposed of, the corporate website continues to operate until all assets are fully disposed of. The company no longer has a board and executives, with all liquidation being managed by outside party Ernst & Young. , filings state that ACE Aviation Holdings consisted of only cash and cash equivalents amounting to a total of CA$6,7 million.

On March 15, 2024, the company was dissolved.
