At Alterra, we define urban living with our exceptionally high standards of construction, masterfully crafting buildings that go on to define the neighbourhood.

Because in order to define a neighbourhood, you must first understand it.

We go this extra mile because we profoundly understand the complex relationship between people and places, and our success emerges from this understanding. From concept to completion, it is the guiding force behind every decision we make.

Inspired by our past and committed to the future growth of the Greater Toronto Area, DiamondCorp is dedicated to developing innovative, high-quality and award-winning residential, mixed-use, and master-planned developments.

DiamondCorp’s exceptional reputation in planning and development stems from our expertise in achieving municipal approvals for complicated sites that translate into outstanding communities. Collaborating with local Councillors, City Staff, and community groups, DiamondCorp’s ability to create developments that are integrated into existing neighbourhoods while still achieving ambitious city building objectives is unparalleled.

Since its founding in 2008, DiamondCorp has invested in 24 development projects across the GTA, totalling 21+ million square feet of development density.

DiamondCorp is the manager of the five Whitecastle New Urban Funds which represent approximately $930 million in capital.
