Laurence 'Larry' Michael Tanenbaum, O.C., is a Canadian businessman, the self-made billionaire Chairman and CEO of Maple Leaf Sports & Entertainment (MLSE), one of North America's largest sports conglomerates. His wealth is rooted in the essential construction and industrial sectors.

Tanenbaum graduated from Cornell University with a degree in Economics. His career began in the family's construction business, York Marble Tile & Terrazzo Ltd. (founded by his father). His philosophy centers on scale, long-term civic commitment, and vertical integration (controlling the teams, the real estate, and the media rights).

• Maple Leaf Sports & Entertainment (MLSE) (Chairman & CEO): The core private asset, a massive sports conglomerate owning the Toronto Raptors (NBA), Toronto Maple Leafs (NHL), and Toronto FC (MLS).
• Investment Strategy: His success is built on consolidating all major professional sports teams in Toronto under one entity and owning the real estate (Scotiabank Arena).
• Philanthropy: He is a major donor to healthcare and medical research (funding the Larry and Judy Tanenbaum Diabetes Centre at Mount Sinai Hospital).

Larry Tanenbaum's strategic genius was his visionary approach to sports consolidation.

His career is also marked by his leadership of Kilmer Group, a major investment firm focused on construction, infrastructure, and private equity.
