Kilmer Group (Tanenbaum Family Office)
Kilmer Group was established in 1954 when the Tanenbaum family acquired and scaled Kilmer Van Nostrand, a civil engineering and construction firm. The office remains headquartered in Toronto and continues to operate as a multi-generational holding company focused on business development and investment. The firm allocates across private equity, infrastructure, real estate, and sports and media. Investment types include direct co-investments, SPVs, buyouts, and growth equity. Confirmed positions encompass Canary District, the former Pan/Parapan American Athletes' Village in Toronto, and Reunion Crossing, a mixed-use project at 1808 St Clair Ave W. Additional holdings include industrial sites in Mississauga and Markham. Geographic reach covers North America and Europe. OMERS acquired a 20 percent stake in Kilmer Sports Inc. in a prior transaction. The office maintains no disclosed headcount or AUM figure. Adjacent vehicles include the Larry and Judy Tanenbaum Family Foundation and The Carol Sharyn Tanenbaum Family Foundation. Larry Tanenbaum serves on the NBA Board of Governors. Ivan Gazidis acts as President of Kilmer Sports Ventures. No operational events from the last 24 months appear in available records. The family office structure embeds operating expertise from the original construction business into investment selection and governance. This produces direct ownership of sports franchises and real-estate developments alongside traditional private-equity and infrastructure mandates.
