Tower Hill Development Corporation is a family-owned private real estate company with roots dating to the early 1940s and more than 70 years of development experience in the Toronto area. The company was established around a family-led vision for creating residential communities and has since expanded across land development, home building, condominium development, and rental apartments. Its portfolio includes single-family homes, townhomes, luxury condominiums, and rental apartment buildings, with development activity primarily across the Greater Toronto Area. The company’s current leadership is identified as President Robert Marvin Masters, Q.C., with Randolph Masters and Russell Masters serving as Vice-Presidents, reflecting the continuing involvement of the Masters family. Tower Hill emphasizes quality over quantity, detailed project execution, innovative architecture, and long-term care for residents and communities as core elements of its approach. Its home-building philosophy combines traditional family values with contemporary design and community planning, while its stated standards emphasize quality specifications and customer service. Current residential activity includes New Seaton in north Pickering, where Tower Hill is developing townhomes, semis, and single-detached homes within a master-planned community.
