Mattamy Asset Management

Mattamy Asset Management

Peter Gilgan established Mattamy Asset Management in 2018 as the dedicated investment vehicle for the wealth generated by Mattamy Homes, the residential construction giant he founded in 1978. Gilgan grew the homebuilder from a single house in Burlington, Ontario into the largest privately owned homebuilder in North America, with operations spanning the Greater Toronto Area, Calgary, Ottawa, and numerous US markets including Florida, Arizona, and the Carolinas. The family office represents a formal separation of the Gilgan family's operating business wealth from its diversified investment activities. Mattamy Asset Management deploys capital across a broad mandate that includes real estate equity and debt, private equity, venture capital, and public market securities. The firm pursues direct investments, fund commitments, and co-investments alongside external managers. Its real estate exposure extends beyond Mattamy Homes into income-producing properties and development projects in Canada and the United States. The venture portfolio targets early and growth-stage companies, with public records indicating positions in technology and healthcare startups (per public record). Public equities and fixed income round out the allocation, managed through a combination of internal expertise and external manager relationships. The firm operates from Toronto with a lean team structure characteristic of single-family offices managing concentrated wealth. Gilgan's philanthropic activities are conducted through the Peter Gilgan Foundation, a separate entity that has committed over $200 million to healthcare, education, and community organizations, including a $100 million donation to the Hospital for Sick Children in Toronto in 2019 (per public record). The foundation's scale and independence from the asset manager represent a governance distinction common among institutional-grade family offices. No additional office locations beyond Toronto are publicly confirmed for the asset management entity. Mattamy Asset Management's structural distinction lies in its relationship to an operating company that remains privately held and actively managed. Unlike family offices formed after a liquidity event or public listing, the Gilgan structure must manage concurrent capital allocation to the core homebuilding business and the diversified portfolio. This creates an ongoing tension between reinvestment in the founder's legacy company and deployment into unrelated strategies — a dynamic that shapes the office's pacing, liquidity management, and long-term asset allocation more than a typical post-exit family office.
