About DiamondCorp

Building on a Legacy

Founded in 2008 by Stephen Diamond, DiamondCorp was built on the legacy of development excellence established by his father, the late Ephraim Diamond, almost 70 years ago. Committed to the future growth of the Greater Toronto Area, DiamondCorp brings forward a history of dedication and experience to develop innovative, high-quality, award-winning communities.

We recognize the potential of under-utilized sites and apply practical solutions to planning policies and objectives.

By partnering with private and public sector organizations and working with councillors, municipal staff, and community groups, DiamondCorp has built a reputation as a creative developer with real-world solutions to complex challenges.
