Is Onex Corporation publicly traded?

Despite being publicly traded, Onex operates as a private equity firm, generating revenue primarily through management fees and carried interest from its investment funds.

Who founded Onex Corporation?
Onex Corporation was founded in 1984 by Gerald W. Schwartz, a Canadian businessman who previously worked at Bear Stearns in New York. Schwartz established Onex as one of Canada's first private equity firms and continues to serve as Founder and Non-Independent Chairman. Robert Le Blanc currently serves as CEO.

What companies does Onex own?
Onex's current portfolio includes WestJet (Canada's second-largest airline), Convex (specialty insurance), AirSprint (fractional jet ownership), and a significant minority stake in OneDigital (insurance brokerage and financial services), among other investments. The portfolio changes as Onex acquires new platform companies and exits existing investments through sales or public offerings.

How much did Onex pay for WestJet?
Onex Corporation acquired WestJet in December 2019 for approximately CAD $5 billion through its Onex Partners platform. The deal priced WestJet shares at $31 each, a 67 percent premium over the closing price before the offer. It was the largest private equity deal in aviation history at the time. In October 2025, Onex sold a 25 percent minority stake to Delta Air Lines, Korean Air, and Air France-KLM for approximately US $550 million, recouping its equity investment while retaining 75 percent control.

Did Onex try to buy Air Canada?
Yes. In 1999, Onex launched a hostile takeover bid for Air Canada, proposing to merge it with Canadian Airlines. A Quebec Superior Court ruled the bid illegal because Canadian law prohibited any single shareholder from controlling more than 10 percent of Air Canada. Onex withdrew its offer. Air Canada subsequently merged with Canadian Airlines without Onex's involvement. This experience gave Onex deep familiarity with Canadian aviation regulations, which proved valuable in the 2019 WestJet acquisition.

What is Onex's assets under management?
Onex Corporation has approximately $55.8 billion in assets under management as of 2026. Of this total, approximately $9.4 billion represents Onex's own investing capital. The Onex Partners platform alone manages approximately $17 billion. The firm's investors include public and private pension plans, sovereign wealth funds, insurance companies, family offices, and high-net-worth individuals globally.
