Senior Preconstruction Estimator

ADI Development Group ranks among Canada's most forward-thinking real estate development, construction management, and investment firms. With more than 4,000 units and $3 billion in built value across the GTHA, we're on a bold mission to transform the home buying experience—delivering better-quality homes faster and more efficiently than anyone else in the market.

The people who thrive at ADI are passionate about their work, decisive by nature, and genuinely committed to growth. We push each other to think differently through honest, respectful dialogue—and when a decision is made, we align and execute as one team. Shared challenge. Shared learning. Shared wins.

We are looking for a seasoned Preconstruction Estimator to join our expanding team. You will take ownership of the full estimating process—from initial feasibility through construction documentation—serving as a key voice in how ADI's projects are structured, designed, and financially positioned. Working alongside internal development, design, and construction teams as well as outside consultants, you'll help ensure every project is economically sound, competitively priced, and set up for precise execution.

If you're an estimator who does your best work in a high-energy, entrepreneurial setting and wants a real seat at the table on major high-rise and mixed-use projects, this is the role for you.
