Onex Corporation is a major Canadian investment management firm that operates as a public company traded on the Toronto Stock Exchange.

Founded in 1984 by Gerry Schwartz, Onex Corporation is one of Canada's oldest and most prominent investment firms. The company went public in 1987 and has since grown into a diversified manager of private equity funds, investment vehicles, and credit strategies. It is headquartered in Toronto and maintains a significant presence in the global alternative asset market.

The firm's investment history includes high-profile acquisitions across various sectors, ranging from aerospace and automotive to healthcare and air transportation. Notable milestones include the purchase of Allison Transmission from General Motors and the 2019 acquisition of WestJet, Canada's second-largest airline. Despite facing significant headwinds during the COVID-19 pandemic, the firm remains a major player in the private equity space.

In recent years, Onex has expanded its capabilities through strategic acquisitions like the wealth management firm Gluskin Sheff. The firm underwent a significant leadership transition in 2022 when founder Gerry Schwartz stepped down as CEO, passing the leadership to Bobby Le Blanc. Today, Onex manages tens of billions of dollars for institutional and high-net-worth investors worldwide.
