Onex Corporation is a prominent Canadian investment management firm that operates across private equity, credit, and wealth management sectors.

Founded in 1984 by Gerry Schwartz, Onex Corporation is one of Canada's oldest and largest investment firms. The company went public on the Toronto Stock Exchange in 1987 and has since grown into a multi-strategy manager. It significantly expanded its reach through major acquisitions and the establishment of various private equity and credit platforms.

The firm's historical activity includes high-profile industrial and aerospace deals, such as the acquisition of Allison Transmission from General Motors and the purchase of WestJet. While originally focused on private equity buyouts, Onex has diversified into wealth management through the acquisition of Gluskin Sheff and maintains a robust presence in credit markets. Despite facing challenges like the COVID-19 pandemic, which led to a $1.1 billion loss in early 2020, the firm remains a central player in the global private equity landscape.
