Cornerstone Association of REALTORS® Names Chair-Elect and CEO

June 3, 2024 — The Amalgamation Task Force (ATF) for the Cornerstone Association of REALTORS® (Cornerstone) is pleased to announce it has elected Drew Hemsley as Chair-Elect, and selected Bill Duce as the Chief Executive Officer.

Cornerstone formally launches on July 1, 2024, and unites REALTORS® from the Hamilton-Burlington, Mississauga, Simcoe, and Waterloo Region real estate associations. With close to 9,000 members, Cornerstone forms Ontario’s second-largest and Canada’s fourth-largest real estate board. On April 29, 2024, Julie Sergi was elected as the inaugural Chair of Cornerstone for its 2024/2025 Board of Directors. At the ATF meeting held on May 31, 2024, Drew Hemsley was elected to serve alongside Sergi as Chair-Elect.

Drew Hemsley - Chair-Elect, Cornerstone Association of REALTORS®

A REALTOR® since 2008, Hemsley has served as a Director on the Simcoe and District Real Estate Board (SDREB) since 2022. He is a sales representative with Royal LePage Trius Realty in Port Dover and currently serves as president of SDREB.

Hemsley’s background as the Director of Operations of a large logistics company for almost two decades and as the owner and operator of a successful renovation company provides diverse skills to support Cornerstone, especially during these early years. 

“There will be significant developments in organized real estate within the next decade,” says Hemsley. “I firmly believe that Cornerstone is exceptionally positioned to lead these changes, and I look forward to supporting our Board Chair, Julie Sergi, and our recently hired CEO as we navigate these exciting changes together with our Board of Directors for the benefit of our members.”

Bill Duce - CEO, Cornerstone Association of REALTORS®

Bill Duce has been a leader within the Canadian real estate MLS® and association network for over two decades, most recently as current CEO of the Waterloo Region Association of REALTORS® (WRAR). During his tenure, he participated in the creation of the Ontario Regional Technology & Information Systems (ORTIS) regional initiative, and in 2018, he was one of the project leads for the Information Technology Systems of Ontario (ITSO) regional initiative, which combined the seventeen boards that made up ORTIS and the Ontario Collective groups into one singular regional MLS® System. As CEO of the Kitchener-Waterloo Association of REALTORS®, he led the association through an amalgamation with the Cambridge Association of REALTORS® which formed WRAR in 2022.

“Duce’s extensive experience in leading regional initiatives and association amalgamations will be invaluable in supporting Cornerstone’s overall vision,” says Julie Sergi, Cornerstone’s Chair. “He brings a unique perspective and his record demonstrates he is a visionary and successful at collaborating with diverse stakeholders and streamlining operations.”

“I am a builder at heart, and I look forward to aligning four exceptional associations to create something greater than the sum of its parts,” says Duce. “Organized real estate is overdue for a reset, and Cornerstone has the potential to be on the vanguard of this change while keeping our REALTOR® members central to all we do.”
