Yvan Breton

Yvan Breton is a senior partner at Mercer, the investment and benefits consulting arm of Marsh McLennan, where he has led the firm's investment-consulting and outsourced-CIO (OCIO) businesses. Public records describe him as Partner and Business Leader for Mercer's Investment Consulting business across Canada and Latin America, and as Partner and Head of OCIO / Fiduciary Management Services at Mercer Canada. He has also been referenced as Head of Fiduciary Management and Business Leader for Latin America during his tenure. In these roles he oversees the design and delegated management of institutional portfolios — pension plans, insurers, and other asset owners — rather than early-stage venture capital.

His investment career predates Mercer. He spent roughly five years with Dimensional Fund Advisors in Vancouver and about ten years as a senior investment consultant with Towers Perrin in Calgary, and has been described as having earlier been a Principal at Aon on the consulting side. This trajectory — asset management at Dimensional, then long-horizon investment consulting at Towers Perrin and Aon, then leadership of Mercer's delegated-investment platform — is that of an institutional investment professional and fiduciary-management specialist.

Breton holds a Bachelor of Science and a degree in Actuarial Science (Actuariat) from Université Laval in Quebec, giving him a quantitative, actuarial foundation well suited to liability-driven and pension-oriented investing.

Accuracy note: The known stub data tagged Mr. Breton as an "Angel Investor" investing in "Seed Rounds." Extensive searching found no evidence supporting that — every credible source ties him to Mercer's institutional investment-consulting and OCIO business. This profile therefore reflects his verifiable role and flags the "angel/seed" label as likely mistaken aggregator data rather than repeating it as fact.

• Focus is on outcomes for institutional clients — Breton has framed Mercer's investment leadership around driving "better outcomes for our clients, for people and for society."
• Emphasis on portfolio construction, manager selection, and fiduciary management across Canada and Latin America, drawing on an actuarial background suited to liability-aware and pension investing.
• No public record of a personal angel/seed check-writing thesis, check size, or target startup profile — these are omitted rather than fabricated.

No public record of personal startup or angel-stage portfolio companies attributable to Yvan Breton was found. His investment activity is institutional and delegated (managed on behalf of Mercer's clients through OCIO mandates), so individual "deals" are not publicly disclosed. This section is intentionally left without fabricated entries.
