The Ledger / Peter Gilgan
Peter Gilgan
◼ Origin
Founded Mattamy Homes in Burlington, Ontario, in 1978, building it from a small local home construction company into Canada's largest privately owned homebuilder; Mattamy constructs 7,000–9,000 homes annually across Ontario, Alberta, British Columbia, and major US markets in the Carolinas, Florida, Arizona, and Colorado. Gilgan has maintained Mattamy's private ownership structure rather than pursuing a public listing, and the company has no institutional investors or outside shareholders.
◼ Self-Made Verdict — YES
Founded Mattamy Homes from scratch in 1978 without an inherited construction or real estate business; built Canada's largest private homebuilder through original operational execution and capital accumulation over 45 years.
◼ Documented marks
01
Founder of Mattamy Homes, Canada's largest privately owned homebuilder; Mattamy constructs 7,000–9,000 homes annually across Ontario, Alberta, British Columbia, and US markets (North Carolina, South Carolina, Florida, Arizona, Colorado), making Gilgan one of the most influential private actors in North American residential real estate development.
02
Mattamy Homes has been among the homebuilders most active in Canada's contested greenbelt and urban growth boundary debates; the company holds significant land banks in Ontario's protected greenbelt and exurban areas, and has advocated for land-use regulation changes that would allow development of those holdings — intersecting with political controversies around Ontario's 2022–2023 greenbelt land swaps.
03
Gilgan donated $50M to the Hospital for Sick Children (SickKids) in Toronto — one of the largest individual donations in Canadian hospital history — and Mattamy has been a significant donor to Canadian political parties across the spectrum; the combination of development advocacy and philanthropy illustrates how private homebuilders use both policy lobbying and community investment to maintain political relationships.
