Harold Douma has been helping clients successfully buy and sell real estate across Eastern Ontario since 2011, earning a strong reputation for guiding both sellers and buyers through a smooth, well-managed process. Based in Cornwall, Harold services a wide area along the Highway 401 corridor—from Lancaster to Brockville—as well as inland communities including Winchester, Chesterville, Morewood, Finch, and surrounding rural and agricultural regions.

Known for his practical approach and steady guidance, Harold works closely with sellers to ensure their property is positioned effectively in today’s market, while also helping buyers make confident, informed decisions. From understanding true property value to preparing a home or farm for sale—or identifying the right opportunity to purchase—he focuses on the details that make a meaningful difference in achieving the best possible outcome.

With over 30 years of farming experience, Harold offers a level of insight that is especially valuable when working with rural and agricultural properties. His knowledge of zoning, land use, and soil composition helps sellers present their property with clarity and confidence, while giving buyers a deeper understanding of what they are purchasing. Combined with his background as a former Home Inspector and Landlord, he brings a well-rounded perspective to residential and multi-family properties—often identifying opportunities and considerations before they become obstacles.

Harold’s consistent results have earned him Top Producing Awards at EXIT Realty Seaway, along with Bronze Awards from EXIT International. His business is built on trust, straightforward communication, and a commitment to doing things properly from start to finish—whether guiding a seller through the listing process or supporting a buyer from first showing to closing.

He is also known for supporting others in the industry, offering guidance to those considering a career in real estate and mentoring REALTORS® who are looking to grow within a supportive, team-oriented environment at EXIT Realty Seaway.

A dedicated family man, Harold has been married to his wife Mary for 50 years. Together, they have three children and ten grandchildren, and they enjoy spending time together camping during the summer months. In his spare time, Harold enjoys golfing, cycling, and restoring antique tractors, and remains actively involved in his community through School Board and Church Council service.

For those considering a move—whether selling, buying, or both—Harold offers a thoughtful, experienced approach and a clear understanding of what it takes to navigate today’s market with confidence.
