Peter Gilgan founded Mattamy Homes in 1978 and built it into North America's largest privately owned homebuilder by rethinking how suburbs are designed. Beyond real estate, he is one of Canada's most active philanthropists, donating hundreds of millions to healthcare, education, and community infrastructure. This profile explores his strategies for navigating market cycles, his push toward modular housing, and his philosophy on using capital to drive systemic change.
