What DiamondCorp does

DiamondCorp is a Toronto-based real estate development company founded in 2008 by Stephen Diamond, continuing a multi-generational development legacy that traces back to his father Ephraim Diamond's co-founding of Cadillac Development Corporation (now Cadillac Fairview) in 1953. The company develops residential, mixed-use, and master-planned communities across the Greater Toronto Area (GTA), with a portfolio encompassing 31 projects, 27,000+ residential units, and 25+ million square feet of development footprint. DiamondCorp manages five Whitecastle New Urban Private Equity Real Estate Funds representing approximately $1 billion in committed equity and oversees more than $2 billion in real estate assets in the GTA.

The company's revenue model is based on one-time sales of residential condominiums, townhouses, and mixed-use units, with revenue recognized upon unit closings. Pricing is quote-based and varies by unit type, size, floor level, and community; buyers register on the website or visit presentation centres (such as Q Tower's Presentation Centre) for pricing details. Distribution is direct-to-consumer through presentation centres and model suite showrooms, supplemented by realtor referral partnerships. DiamondCorp executes projects through a mix of wholly-owned developments and strategic joint ventures, most notably Diamond Kilmer Developments (with Kilmer Group) and co-development partnerships with Lifetime Developments, Cadillac Fairview, Alterra, and Daniels Corporation.

The company's core competency is navigating complex municipal approvals and zoning processes in the GTA — an expertise underpinned by Stephen Diamond's 30+ years of municipal law experience and a development team (led by VPs Kate Hatoum and Caitlin Willcocks) collectively responsible for millions of square feet of secured redevelopment approvals. Key projects include Q Tower (60-storey waterfront, groundbreaking January 2026), Brightwater (72-acre master-planned community in Port Credit), Reunion Crossing (Diamond Kilmer JV), Celeste Condominiums (with Alterra), and CF Sherway Gardens master plan (with Cadillac Fairview). The company serves two primary customer segments: individual homebuyers seeking primary residence or homeownership, and real estate investors seeking properties with appreciation and rental income potential.
