About The Position

ADI Development Group is one of Canada’s leading and most innovative real estate development, construction management, and investment companies. With over 4,000 units and $3 billion of built value under development across the GTHA, we are on an insurgent mission to reinvent the customer experience—delivering homes faster, better, and more cost-effectively than anyone in the market.
Successful Adians care deeply about their craft, work with a bias toward action, and commit to continuously learning and growing. They challenge each other’s thinking through respectful debate, align behind decisions, and move forward together. We face adversity together. We learn together. We win together.
We are seeking an experienced Preconstruction Estimator to join our growing Preconstruction team. In this role, you will own the full estimating lifecycle from early feasibility through construction document stages—playing a critical role in shaping how ADI’s projects are conceived, designed, and priced. You will collaborate closely with internal development, design, and construction teams as well as external consultants to ensure our projects are economically viable, competitively bid, and built with precision.
This is a high-impact role for an estimator who thrives in a fast-paced, entrepreneurial environment and wants to influence real decisions at the front end of major high-rise and mixed-use projects.
